Clean energy contributed a record 11.4tn yuan ($1.6tn) to China’s economy in 2023, accounting for all of the growth in investment and a larger share of economic growth than any other sector.
The new sector-by-sector analysis for Carbon Brief, based on official figures, industry data and analyst reports, illustrates the huge surge in investment in Chinese clean energy last year – in particular, the so-called “new three” industries of solar power, electric vehicles (EVs) and batteries.
Solar power, along with manufacturing capacity for solar panels, EVs and batteries, were the main focus of China’s clean-energy investments in 2023, the analysis shows.
(For this analysis, we used a broad definition of “clean energy” sectors, including renewables, nuclear power, electricity grids, energy storage, EVs and railways. These are technologies and infrastructure needed to decarbonise China’s production and use of energy.)
Other key findings of the analysis include:
- Clean-energy investment rose 40% year-on-year to 6.3tn yuan ($890bn), with the growth accounting for all of the investment growth across the Chinese economy in 2023.
- China’s $890bn investment in clean-energy sectors is almost as large as total global investments in fossil fuel supply in 2023 – and similar to the GDP of Switzerland or Turkey.
- Including the value of production, clean-energy sectors contributed 11.4tn yuan ($1.6tn) to the Chinese economy in 2023, up 30% year-on-year.
- Clean-energy sectors, as a result, were the largest driver of China’ economic growth overall, accounting for 40% of the expansion of GDP in 2023.
- Without the growth from clean-energy sectors, China’s GDP would have missed the government’s growth target of “around 5%”, rising by only 3.0% instead of 5.2%.
The surge in clean-energy investment comes as China’s real-estate sector shrank for the second year in a row. This shift positions the clean-energy industry as a key part not only of China’s energy and climate efforts, but also of its broader economic and industrial policy.
However, the spectre of overcapacity means China’s clean-energy investment growth – and its investment-driven economic model, in general – cannot continue indefinitely.
The growing importance of these new industries gives China a significant economic stake in the global transition to clean-energy technologies.
Yet it also poses questions for overseas policymakers attempting to tie their own climate strategies to domestic industrial growth.

Clean energy drives China’s growth in 2023
China’s clean-energy investment boom means the sector accounted for all of the growth in investment across the country’s economy in 2023, with spending in other areas shrinking.
China invested an estimated 6.3tn yuan ($890bn) in clean-energy sectors in 2023, up from 4.6tn yuan in 2022, a 1.7tn yuan (40%) year-on-year increase. In total, clean energy made up 13% of the huge volume of investment in fixed assets in China in 2023, up from 9% a year earlier.
With Chinese investment growing by just 1.5tn yuan in 2023 overall, the analysis shows that clean energy accounted for all of the growth, while investment in sectors such as real estate shrank.
This is shown in the figure below, which also highlights the concentration of clean-energy investment in the so-called “new three” of solar, energy storage and EVs.
Clean energy was also the top contributor to China’s economic growth overall, contributing around 40% of the year-on-year increase in GDP across all sectors.

Including the value of goods and services, the clean-energy sector contributed an estimated 11.4tn yuan ($1.6tn) to China’s economy in 2023, an increase of 30% year-on-year.
This means clean energy accounted for 9.0% of China’s GDP in 2023, up from 7.2% in 2022.
Without the contribution of clean-energy sectors to China’s economic growth in 2023, the country would have seen its GDP rise by just 3.0%, instead of the 5.2% actually recorded.
This would have missed government growth targets at a time of increasing concerns over the nation’s economic prospects, amid the ongoing real-estate crisis and declining population.
The major role that clean energy played in boosting growth in 2023 means the industry is now a key part of China’s wider economic and industrial development.
This is likely to bolster China’s climate and energy policies – as well as its “dual carbon” targets for 2030 and 2060 – by enhancing the economic and political relevance of the sector.
The ‘new three’ dominate clean-energy investment
This analysis is based on a combination of government releases, industry data and analyst reports, with the exact methodology varying sector-by-sector, as set out in the sections that follow.
The table below lists the estimated contributions of each sector to Chinese investment and GDP overall in 2023, as well as the year-on-year growth since 2022.
The analysis includes solar, EVs, energy efficiency, rail, energy storage, electricity grids, wind, nuclear and hydropower within the broad category of “clean-energy sectors”. All of these are technologies and infrastructure needed to decarbonise China’s energy supply and consumption.
The so-called “new three” of solar, storage and EVs are all prominent in the table – and all recorded strong growth.
Our analysis shows that investment in clean power generation and energy storage capacity reached 1.7tn yuan in 2023 (up 48% year-on-year), while investment in manufacturing capacity for solar, EVs and batteries reached 2.5tn yuan (+60%).
Investment in clean-energy infrastructure reached 1.4tn yuan (+9%, comprising grids, EV charging points and railways) and investment in energy efficiency was 600bn yuan (+15%).
Meanwhile, our analysis shows the value of production of goods and services in the clean-technology sectors reached 5.1tn yuan in 2023, increasing 26% year-on-year.
This includes the value of electricity generation, EV sales and solar exports, as well as the transport of passengers and goods via rail.

Solar power
Solar was the largest contributor to growth in China’s clean-technology economy in 2023. It recorded growth worth a combined 1tn yuan of new investment, goods and services, as its value grew from 1.5tn yuan in 2022 to 2.5tn yuan in 2023, an increase of 63% year-on-year.
While China has dominated the manufacturing and installations of solar panels for years, the growth of the industry in 2023 was unprecedented.
On the installation side, two major central government initiatives drove increased volumes, namely the “whole-county distributed solar” and the “clean energy base” programmes.
In addition, in response to the slowdown in the real-estate sector, the central government introduced a new policy at the start of 2023, to encourage the development of solar power industries on unused and existing construction lands.
Meanwhile, during the annual legislative meetings in the spring of 2023, 15 provinces prioritised solar industry development in their government work agendas.
Detailed data on the growth in China’s solar installations in the first 11 months of the year is shown in the figure below. (An estimated 200GW was added across the country during 2023 as a whole, more than doubling from the record of 87GW set in 2022.)

At the same time, China’s solar manufacturing industry recorded even stronger growth in 2023. China added 340 gigawatts (GW) of polysilicon production capacity and 300GW of wafer, cell and module production capacity in 2023, according to the International Energy Agency (IEA).
China experienced a significant increase in solar product exports in 2023. It exported 56GW of solar wafers, 32GW of cells and 178GW of modules in the first 10 months of the year, up 90%, 72% and 34% year-on-year respectively, according to the China Photovoltaic Industry Association. However, due to falling costs, the export value of these solar products only increased by 3%.
Within the overall export growth there were notable increases in China’s solar exports to countries along the “belt and road”, to southeast Asian nations and to several African countries.
For this analysis, the value of investments in new solar manufacturing capacity was estimated from the average capital costs of each step in the supply chain, taken from a compilation of reported project costs. This gave a significantly lower cost level than reported in other literature.
The analysis assumes that local government investment in facilities and infrastructure, as well as direct subsidies, added 30% to the reported private investment.
Investment in solar power was estimated by multiplying the newly added capacity from Bloomberg New Energy Finance by the unit investment costs for rooftop and utility-scale systems from China Photovoltaic Industry Association.
The value of exported solar power equipment was based on China Photovoltaic Industry Association data for 2022 and reported export growth for 2023.
The value of solar power equipment produced for domestic installation was not included in our analysis, to avoid overlap with the already-estimated investment costs for domestic solar projects.
Wind power
China installed 41GW of wind power capacity in the first 11 months of 2023, an increase of 84% year-on-year in new additions. Some 60GW of onshore wind alone was due to be added across 2023, according to China Galaxy Securities, based on trends in previous years.
In addition, offshore wind capacity increased by 6GW across the whole of 2023.
Wind capacity added in the first 11 months of each year is shown in the figure below.

By the end of 2023, the first batch of “clean-energy bases” were expected to have been connected to the grid, contributing to the growth of onshore wind power, particularly in regions such as Inner Mongolia and other northwestern provinces. The second and third batches of clean-energy bases are set to continue driving the growth in onshore wind installations.
The market is also being driven by the “repowering” of older windfarms, supported by central government policies promoting the model of replacing smaller, older turbines with larger ones.
The potential for distributed wind power is also being explored, with initiatives such as the “villages wind utilisation action” being planned for active implementation.
Progress on offshore wind power construction in 2023 got off to a slow start. This is a reflection of a shift from nearshore to deeper offshore projects and from single projects to larger bases.
Offshore wind projects are also facing complex approval processes, involving multiple regulatory aspects, leading to uncertainties and slower-than-expected installations.
However, these issues are being addressed and the fourth quarter of 2023 saw a rebound in offshore wind construction, with 2024 expected to be a significant year for project deliveries.
Since 2021, new wind projects in China no longer receive subsidies from the central government.
Despite technological advancements reducing costs, increases in raw material prices have resulted in lower profit margins compared to the solar industry, leading to a smaller overall investment in wind power relative to solar power.
Electric vehicles
China’s production of electric vehicles grew 36% year-on-year in 2023 to reach 9.6m units, a notable 32% of all vehicles produced in the country.
The vast majority of EVs produced in China are sold domestically, with sales growing strongly despite the phase-out of purchase subsidies announced in 2020 and completed at the end of 2022.
The national purchase subsidy for EVs was a central government finance instrument that had been fostering the EV market for 13 years. Its demise highlights a gradual shift from policy-driven to market-driven demand, making growth more likely to be sustained.
Sales of EVs made in China reached 9.5m units in 2023, a 38% year-on-year increase. Of this total, 8.3m were sold domestically, accounting for one-third of Chinese vehicle sales overall, while 1.2m EVs were exported, a 78% year-on-year increase.
The growth of “new energy vehicle” (NEV, mainly EVs) production and sales is shown in the figure below, which also shows their rising share of all vehicles sold.

China’s EV market is highly competitive, with at least 94 brands offering more than 300 models. Domestic brands account for 81% of the EV market, with BYD, Wuling, Chery, Changan and GAC among the top players.
Sustaining this growth has required major investment in manufacturing capacity.
This analysis estimates investments in EV manufacturing capacity based on a study by China International Association for Promotion of Science and Technology (CIAPST), which put investment in EV manufacturing at 0.7tn yuan in 2021.
The analysis assumes that EVs accounted for all of the growth in investment in vehicle manufacturing capacity reported by China’s national bureau of statistics (NBS) in 2022 and 2023, while investment in conventional vehicles was stable
This implies that investment in EV manufacturing reached CNY 1.2tn yuan in 2023. This is likely to be conservative, because production volumes for combustion engine vehicles are falling, implying a corresponding fall in investment.
This analysis accounts for the expansion of battery manufacturing capacity separately – alongside electricity storage – even though it is being driven by the growth in EV production.
The analysis estimates the value of EV production, including both domestic sales and exports, based on vehicle production volumes from NBS and the reported average EV price.
These EV prices include the value of batteries produced for EVs, so the value of battery production is not included separately.
Meanwhile, EV charging infrastructure is expanding rapidly, enabling the growth of the EV market. In 2022, more than 80% of the downtown areas of “first-tier” cities – megacities such as Beijing, Shanghai and Guangzhou – had installed charging stations, while 65% of the highway service zones nationwide provided charging points.
More than 3m new charging points were put into service during 2023, including 0.93m public and 2.45m private chargers. The accumulated total by November 2023 reached 8.6m charging points.
This analysis puts investment in EV charging infrastructure at 0.1tn yuan in 2023, based on an estimated average cost of 30,000 yuan per charging point.
Energy efficiency
China’s energy intensity reduction targets have put pressure on industries to reduce their energy use per unit of output, spurring investment in more efficient processes.
For this analysis, the size of the market for energy service companies is used as a proxy for investment in energy efficiency in industries and buildings. This market grew to an estimated 0.6tn yuan in 2023, up from 0.5tn yuan in 2022, based on the revenue growth of the top 10 listed energy service companies ranked by market capitalization, for the first two or three quarters of 2023.
Over the past two decades, China’s energy service sector has experienced rapid expansion, growing from 1.8bn yuan in 2003 to 607bn yuan in 2021. Investment in the industrial service sector has been a key driver, accounting for about 60% of the total investment.
However, 2022 saw a significant downturn in the industrial energy service output, influenced by poor industrial growth, even though the building service sector continued expanding.
This analysis puts China’s investment in building energy efficiency at 80bn yuan per year. The country’s 14th five-year plan for energy savings in buildings and development of “green buildings” targets 80m square metres per year of renovated and newly built green buildings.
Compared with the almost 1,000m square metres of building space completed annually, this is a small percentage, and accordingly, the estimated value of total investments is modest.
Electricity storage and hydrogen
China is rapidly scaling up electricity storage capacity. This has the potential to significantly reduce China’s reliance on coal- and gas-fired power plants to meet peaks in electricity demand and to facilitate the integration of larger amounts of variable wind and solar power into the grid.
The construction of pumped hydro storage capacity increased dramatically in the last year, with capacity under construction reaching 167GW, up from 120GW a year earlier.
This growth is illustrated in the figure below, which shows pumped hydro capacity under construction or in earlier stages of development at the end of 2023.

Data from Global Energy Monitor identifies another 250GW in pre-construction stages, indicating that there is potential for the current surge in capacity to continue.
For this analysis, estimated annual investments in pumped storage are assumed to be proportional to the capacity under construction, while the reported construction cost of 6 yuan per watt is spread over three years. This implies that investment in 2023 amounted to 0.3tn yuan.
Construction of new battery manufacturing capacity was another major driver of investments, estimated at 0.3tn. This is based on the added capacity reported by the China Automotive Power Battery Industry Innovation Alliance and estimated average investment costs per unit of production capacity, taken from a compilation of publicly reported project costs.
Investment in electrolysers for “green” hydrogen production almost doubled year-on-year in 2023, reaching approximately 90bn yuan, based on estimates for the first half of the year from SWS Research. Analyst reports and compilations of projects published in news media put far larger numbers on China’s investments in green hydrogen, but these generally include the spending on electricity generation, which in this analysis is accounted for separately.
Investment in “new energy storage technologies” – a classification dominated by batteries – more than doubled in 2023, reaching 75bn yuan. This estimate is based on newly added capacity in 2023 reported by China Energy Storage Alliance and average investment costs calculated from National Energy Administration data.
Railways
China’s ministry of transportation reported that investment in railway construction increased 7% in January–November 2023, implying investment of 0.8tn for the full year. This includes major investments in both passenger and freight transport. Investment in roads fell slightly, while investment in railways overall grew by 22%.
The share of freight volumes transported by rail in China has increased from 7.8% in 2017 to 9.2% in 2021, thanks to the rapid development of the railway network.
In 2022, some 155,000km of rail lines were in operation, of which 42,000km were high-speed. This is up from 146,000km of which 38,000km were high-speed in 2020.
The value of passenger and freight transportation on China’s railways increased by 39% year-on-year in 2023, reaching nearly 1tn yuan.
Nuclear power
In 2023, 10 nuclear power units were approved in China, exceeding the anticipated rate of 6-8 units per year set by the China Nuclear Energy Association in 2020 for the second year in a row.
There are 77 nuclear power units that are currently operating or under construction in China, the second-largest total in the world. The total yearly investment in 2023 was estimated for this analysis at 87bn yuan, an increase of 45% year-on-year, based on data for January–November from the National Energy Administration.
The highest numbers of nuclear projects are located in coastal provinces with large concentrations of heavy industry, such as Guangdong, Fujian and Zhejiang, as the development of inland nuclear power projects remains stalled.
These provinces get around 20% of their electricity from nuclear power and continue to expand the technology as part of their efforts to cut emissions from their power sectors.
Electricity grids
China’s power-sector development plans include a major increase in inter-provincial electricity transmission capacity and numerous long-distance transmission lines from west to east.
State Grid, the government-owned operator that runs the majority of the country’s electricity transmission network, has a target to raise inter-provincial power transmission capacity to 300GW by 2025 and 370GW by 2030, from 230GW in 2021. These plans play a major role in enabling the development of clean energy bases in western China.
China Electricity Council reported investments in electricity transmission at 0.5tn yuan in 2023, up 8% on year – just ahead of the level targeted by State Grid.
Why clean energy took off in 2023
The clean-energy investment boom in 2023 is the outcome of a major pivot in China’s macroeconomic strategy. As this analysis shows, investment flowed from real estate into manufacturing – primarily in the clean-energy sector.
Total investment in the manufacturing industry increased by 9% year-on-year in 2023, while investment in the power and heat sectors climbed 23%. These increases were entirely due to growth in investment in clean energy, with investment in other areas falling. Therefore, China’s pivot into manufacturing was, in reality, a pivot to cleantech manufacturing.
The reason for this pivot was the contraction in the real-estate sector, where investment fell by 10% year-on-year in 2022 and another 9% in 2023. While this drop was in line with the government’s aim to address financial risks and excess leverage in the sector, it left a major hole in aggregate investment demand and in the revenue of China’s local governments.
Local governments were under pressure to attract investment, meaning that they offered generous subsidies and helped arrange financing.
The central government, for its part, eased private-sector access to financial markets and bank loans during the Covid-19 pandemic, facilitating the growth of the clean-energy sector.
Unlike the state-owned firms dominating traditional industries, the low-carbon sector, largely composed of private companies, gained access to previously constrained credit.
The significance of this economic shift is reflected not only in the figures revealed by this analysis but also in the language being used by Chinese media.
The three largest of clean-energy sectors by value, namely solar, storage and EVs, are being referred to as the “new three”, in contrast to the “old three” – clothing, home appliances and furniture.
This pivot was only possible because China’s clean-energy policies and wider industrial policy had built the foundation and scaled up these sectors so that they were primed for rapid growth.
The post-Covid credit “push” for clean energy growth also coincided with a demand “pull”, driven by falling costs and the increased competitiveness of low-carbon technologies against fossil fuels due to technological advancements.
Moreover, the announcement in 2020 of the 2060 carbon neutrality target had raised expectations and provided the political signal for the scale-up.
What clean-energy growth means for China – and the world
Clean technology has been an important part of China’s energy policy, industrial strategy and climate change efforts for a long time. Last year marked the first time that the sector also became a key economic driver for the country. This has important implications.
China’s reliance on the clean-technology sectors to drive growth and achieve key economic targets boosts their economic and political importance. It could also support an accelerated energy transition.
The massive investment in clean technology manufacturing capacity and exports last year means that China has a major stake in the success of clean energy in the rest of the world and in building up export markets.
For example, China’s lead climate negotiator Su Wei recently highlighted that the goal of tripling renewable energy capacity globally, agreed in the COP28 UN climate summit in December, is a major benefit to China’s new energy industry. This will likely also mean that China’s efforts to finance and develop clean energy projects overseas will intensify.
Globally, China’s unprecedented clean-energy manufacturing boom has pushed down prices, with the cost of solar panels falling 42% year-on-year – a dramatic drop even compared to the historical average of around 17% per year, while battery prices fell by an even steeper 50%.
This, in turn, has encouraged much faster take-up of clean-energy technologies.
Projections of solar power deployment, in particular, have been upended. The IEA’s latest World Energy Outlook introduced an additional global energy scenario just to look at the implications, projecting that if global deployment of solar power and grid-connected batteries follows the expansion of manufacturing capacity, then global power-sector coal use and carbon dioxide emissions could be a sizable 15% lower than in the base case by 2030. Most of the additional deployment of solar in the IEA’s revised projections is in China.
Even with the increased deployment, however, there is a limit to how much solar power, batteries and other clean technology can be absorbed, as the manufacturing expansion has already saturated most of the global market.
This means that the expansion will run into overcapacity, if maintained. On the other hand, in order to keep driving growth in investment, clean-technology manufacturing would need to not only absorb as much capital as it did in 2023, but keep increasing investment year after year.
The clean-technology investment boom has provided a new lease of life to China’s investment-led economic model. There are new clean-energy technologies where there is scope for expansion, such as electrolysers.
Eventually, however, entirely new sectors will have to be found for investment – or China’s economic model will have to be transformed once there is nowhere left for investment to flow.
The manufacturing boom also cements China’s dominant position in clean-energy supply chains. Other countries therefore face a choice of whether they want to benefit from the low-cost supply of solar panels, batteries, EVs and other clean-energy technology from China.
The alternative is diversifying their supply and paying the cost of building new supply chains, in the form of subsidies and import tariffs required to enable domestic producers or producers in third countries to compete against Chinese suppliers. Such efforts would further increase supply and push down global prices even further.

DeBriefed 23 January 2026: Trump’s Davos tirade; EU wind and solar milestone; High seas hope
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Trump vs world
TILTING AT ‘WINDMILLS’: At the World Economic Forum meeting in Davos, Switzerland, Donald Trump was quoted by Reuters as saying – falsely – that China makes almost all of the world’s “windmills”, but he had not “been able to find any windfarms in China”, calling China’s buyers “stupid”. The newswire added that China “defended its wind power development” at Davos, with spokesperson Guo Jiakun saying the country’s efforts to tackle climate change and promote renewable energy in the world are “obvious to all”.
SPEECH FACTCHECKED: The Guardian factchecked Trump’s speech, noting China has more wind capacity than any other country, with 40% of global wind generation in 2024 in China. See Carbon Brief’s chart on this topic, posted on BlueSky by Dr Simon Evans.
GREENLAND GRAB: Trump “abruptly stepped back” from threats to seize Greenland with the use of force or leveraging tariffs, downplaying the dispute as a “small ask” for a “piece of ice”, reported Reuters. The Washington Post noted that, while Trump calls climate change “a hoax”, Greenland’s described value is partly due to Arctic environmental shifts opening up new sea routes. French president Macron slammed the White House’s “new colonial approach”, emphasising that climate and energy security remain European “top priorities”, according to BusinessGreen.
Around the world
- EU MILESTONE: For the first time, wind and solar generated more electricity than fossil fuels in the EU last year, reported Reuters. Wind and solar generated 30% of the EU’s electricity in 2025, just above 29% from plants running on coal, gas and oil, according to data from the thinktank Ember covered by the newswire.
- WARM HOMES: The UK government announced a £15bn plan for rolling out low-carbon technology in homes, such as rooftop solar and heat pumps. Carbon Brief’s newly published analysis has all the details.
- BIG THAW: Braving weather delays that nearly “derail[ed] their mission”, scientists finally set up camp on Antarctica’s thawing Thwaites glacier, reported the New York Times. Over the next few weeks, they will deploy equipment to understand “how this gargantuan glacier is being corroded” by warming ocean waters.
- EVS WELCOME: Germany re-introduced electric vehicle subsidies, open to all manufacturers, including those in China, reported the Financial Times. Tesla and Volvo could be the first to benefit from Canada’s “move to slash import tariffs on made-in-China” EVs, said Bloomberg.
- SOUTHERN AFRICA FLOODS: The death toll from floods in Mozambique went up to 112, reported the African Press Agency on Thursday. Officials cited the “scale of rainfall” – 250mm in 24 hours – as a key driver, it added. Frontline quoted South African president Cyril Ramaphosa, who linked the crisis to climate change.

Captured

For the first time since monitoring began 15 years ago, there were more UK newspaper editorials published in 2025 opposing climate action than those supporting it, Carbon Brief analysis found. The chart shows the number of editorials arguing for more (blue) and less (red) climate action between 2011-2025. Editorials that took a “balanced” view are not represented in the chart. All 98 editorials opposing climate action were in right-leaning outlets, while nearly all 46 in support were in left-leaning and centrist publications. The trend reveals the scale of the net-zero backlash in the UK’s right-leaning press, highlighting the rapid shift away from a political consensus.
Spotlight
Do the oceans hold hope for international law?
This week, Carbon Brief unpacks what a landmark oceans treaty “entering into force” means and, at a time of backtracking and breach, speaks to experts on the future of international law.
As the world tries to digest the US retreat from international environmental law, historic new protections for the ocean were quietly passed without the US on Saturday.
With little fanfare besides a video message from UN chief Antonio Guterres, a binding UN treaty to protect biodiversity in two-thirds of the Earth’s oceans “entered into force”.
What does the treaty mean and do?
The High Seas Treaty – formally known as the “biodiversity beyond national jurisdiction”, or “BBNJ” agreement – obliges countries to act in the “common heritage of humankind”, setting aside self-interest to protect biodiversity in international waters. (See Carbon Brief’s in-depth explainer on what the treaty means for climate change).
Agreed in 2023, it requires states to undertake rigorous impact assessments to rein in pollution and share benefits from marine genetic resources with coastal communities and countries. States can also propose marine protected areas to help the ocean – and life within it – become more resilient to “stressors”, such as climate change and ocean acidification.
“It’s a beacon of hope in a very dark place,” Dr Siva Thambisetty, an intellectual property expert at the London School of Economics and an adviser to developing countries at UN environmental negotiations, told Carbon Brief.
Who has signed the agreement?
Buoyed by a wave of commitments at last year’s UN Oceans conference in France, the High Seas treaty has been signed by 145 states, with 84 nations ratifying it into domestic law.
“The speed at which [BBNJ] went from treaty adoption to entering into force is remarkable for an agreement of its scope and impact,” said Nichola Clark, from the NGO Pew Trusts, when ratification crossed the 60-country threshold for it to enter into force last September.
For a legally binding treaty, two years to enter into force is quick. The 1997 Kyoto Protocol – which the US rejected in 2001 – took eight years.
While many operative parts of the BBNJ underline respect for “national sovereignty”, experts say it applies to an area outside national borders, giving territorial states a reason to get on board, even if it has implications for the rest of the oceans.
What is US involvement with the treaty?
The US is not a party to the BBNJ’s parent Law of the Sea, or a member of the International Seabed Authority (ISA) overseeing deep-sea mining.
This has meant that it cannot bid for permits to scour the ocean floor for critical minerals. China and Russia still lead the world in the number of deep-sea exploration contracts. (See Carbon Brief’s explainer on deep-sea mining).
In April 2025, the Biden administration issued an executive order to “unleash America’s offshore critical minerals and resources”, drawing a warning from the ISA.
This Tuesday, the Trump administration published a new rule to “fast-track deep-sea mining” outside its territorial waters without “environmental oversight”, reported Agence France-Presse.
Prof Lavanya Rajamani, an expert in international environmental law at the University of Oxford, told Carbon Brief that, while dealing with US unilateralism and “self-interest” is not new to the environmental movement, the way “in which they’re pursuing that self-interest – this time on their own, without any legal justification” has changed. She continued:
“We have to see this not as a remaking of international law, but as a flagrant breach of international law.”
While this is a “testing moment”, Rajamani believes that other states contending with a “powerful, idiosyncratic and unpredictable actor” are not “giving up on decades of multilateralism…they just asking how they might address this moment without fundamentally destabilising” the international legal order.
What next for the treaty?
Last Friday, China announced its bid to host the BBNJ treaty’s secretariat in Xiamen – “a coastal hub that sits on the Taiwan Strait”, reported the South China Morning Post.
China and Brussels currently vie as the strongest contenders for the seat of global ocean governance, given that Chile made its hosting offer days before the country elected a far-right president.
To Thambisetty, preparatory BBNJ meetings in March can serve as an important “pocket of sanity” in a turbulent world. She concluded:
“The rest of us have to find a way to navigate the international order. We have to work towards better times.”

Q&A: What UK’s ‘warm homes plan’ means for climate change and energy bills
The UK government has released its long-awaited “warm homes plan”, detailing support to help people install electric heat pumps, rooftop solar panels and insulation in their homes.
It says up to 5m households could benefit from £15bn of grants and loans earmarked by the government for these upgrades by 2030.
Electrified heating and energy-efficient homes are vital for the UK’s net-zero goals, but the plan also stresses that these measures will cut people’s bills by “hundreds of pounds” a year.
The plan shifts efforts to tackle fuel poverty away from a “fabric-first” approach that starts with insulation, towards the use of electric technologies to lower bills and emissions.
Much of the funding will support people buying heat pumps, but the government has still significantly scaled back its expectations for heat-pump installations in the coming years.
Beyond new funding, there are also new efficiency standards for landlords that could result in nearly 3m rental properties being upgraded over the next four years.
In addition, the government has set out its ambition for scaling up “heat networks”, where many homes and offices are served by communal heating systems.
Carbon Brief has identified the key policies laid out in the warm homes plan, as well as what they mean for the UK’s climate targets and energy bills.

Why do homes matter for UK climate goals?
Buildings are the second-largest source of emissions in the UK, after transport. This is largely due to the gas boilers that keep around 85% of UK homes warm.
Residential buildings produced 52.8m tonnes of carbon dioxide equivalent (MtCO2e) in 2024, around 14% of the nation’s total, according to the latest government figures.
Fossil-fuel heating is by far the largest contributor to building emissions. There are roughly 24m gas boilers and 1.4m oil boilers on the island of Great Britain, according to the National Energy System Operator (NESO).
This has left the UK particularly exposed – along with its gas-reliant power system – to the impact of the global energy crisis, which caused gas prices – and energy bills – to soar.
At the same time, the UK’s old housing stock is often described as among the least energy efficient in Europe. A third of UK households live in “poorly insulated homes” and cannot afford to make improvements, according to University College London research.
This situation leads to more energy being wasted, meaning higher bills and more emissions.
Given their contribution to UK emissions, buildings are “expected to be central” in the nation’s near-term climate goals, delivering 20% of the cuts required to achieve the UK’s 2030 target, according to government adviser the Climate Change Committee (CCC).
(Residential buildings account for roughly 70% of the emissions in the buildings sector, with the rest coming from commercial and public-sector buildings.)
Over recent years, Conservative and Labour governments have announced various measures to cut emissions from homes, including schemes to support people buying electric heat pumps and retrofitting their homes.
However, implementation has been slow. While heat-pump installations have increased, they are not on track to meet the target set by the previous government of 600,000 a year by 2028.
Meanwhile, successive schemes to help households install loft and wall insulation have been launched and then abandoned, meaning installation rates have been slow.
At the same time, the main government-backed scheme designed to lift homes out of fuel poverty, the “energy company obligation” (ECO), has been mired in controversy over low standards, botched installations and – according to a parliamentary inquiry – even fraud.
(The government announced at the latest budget that it was scrapping ECO.)
The CCC noted in its most recent progress report to parliament that “falling behind on buildings decarbonisation will have severe implications for longer-term decarbonisation”.
What is the warm homes plan?
The warm homes plan was part of the Labour party’s election-winning manifesto in 2024, sold at the time as a way to “cut bills for families” through insulation, solar and heat pumps, while creating “tens of thousands of good jobs” and lifting “millions out of fuel poverty”.
It replaces ECO, introduces new support for clean technologies and wraps together various other ongoing policies, such as the “boiler upgrade scheme” (BUS) grants for heat pumps.
The warm homes plan was officially announced by the government in November 2024, stating that up to 300,000 households would benefit from home upgrades in the coming year. However, the plan itself was repeatedly delayed.
In the spending review in June 2025, the government confirmed the £13.2bn in funding for the scheme pledged in the Labour manifesto, covering spending between 2025-26 and 2029-30.
The government said this investment would help cut bills by up to £600 per household through efficiency measures and clean technologies such as heat pumps, solar panels and batteries.
After scrapping ECO at the 2025 budget, the treasury earmarked an extra £1.5bn of funding for the warm homes plan over five years. This is less than the £1bn annual budget for ECO, which was funded via energy bills, but is expected to have lower administrative overheads.
In the foreword to the new plan, secretary of state Ed Miliband says that it will deliver the “biggest public investment in home upgrades in British history”. He adds:
“The warm homes plan [will]…cut bills, tackle fuel poverty, create good jobs and get us off the rollercoaster of international fossil fuel markets.”
Miliband argues in his foreword that the plan will “spread the benefits” of technologies such as solar to households that would otherwise be unable to afford them. He writes: “This historic investment will help millions seize the benefits of electrification.” Miliband concludes:
“This is a landmark plan to make the British people better off, secure our energy independence and tackle the climate crisis.”
What is included in the warm homes plan?
The warm homes plan sets out £15bn of investment over the course of the current parliament to drive uptake of low-carbon technologies and upgrade “up to” 5m homes.
A key focus of the plan is energy security and cost savings for UK households.
The government says its plan will “prioritise” investment in electrification measures, such as heat pumps, solar panels and battery storage. This is where most of the funding is targeted.
However, it also includes new energy-efficiency standards to encourage landlords to improve conditions for renters.
Some policies were notable due to their absence, such as the lack of a target to end gas boiler sales. The plan also states that, while it will consult on the use of hydrogen in heating homes, this is “not yet a proven technology” and therefore any future role would be “limited”.
New funding
Technologies such as heat pumps and rooftop solar panels are essential for the UK to achieve its net-zero goals, but they carry significant up-front costs for households. Plans for expanding their uptake therefore rely on government support.
Following the end of ECO in March, the warm homes plan will help fill the gap in funding for energy-efficiency measures that it is expected to leave.
As the chart below shows, a range of new measures under the warm homes plan – including a mix of grants and loans – as well as more funding for existing schemes, leads to an increase in support out to 2030.

One third of the total funding – £5bn in total – is aimed at low-income households, including social housing tenants. This money will be delivered in the form of grants that could cover the full cost of upgrades.
The plan highlights solar panels, batteries and “cost-effective insulation” for the least energy-efficient homes as priority measures for this funding, with a view to lowering bills.
There is also £2.7bn for the existing boiler upgrade scheme, which will see its annual allocation increase gradually from £295m in 2025-26 to £709m in 2029-30.
This is the government’s measure to encourage better-off “able to pay” households to buy heat pumps, with grants of £7,500 towards the cost of replacing a gas or oil-fired boiler. For the first time, there will also be new £2,500 grants from the scheme for air-to-air heat pumps (See: Heat pumps.)
A key new measure in the plan is £2bn for low- and zero-interest consumer loans, to help with the cost of various home upgrades, including solar panels, batteries and heat pumps.
Previous efforts to support home upgrades with loans have not been successful. However, innovation agency Nesta says the government’s new scheme could play a central role, with the potential for households buying heat pumps to save hundreds of pounds a year, compared to purchases made using regular loans.
The remaining funding over the next four years includes money assigned to heat networks and devolved administrations in Scotland, Wales and Northern Ireland, which are responsible for their own plans to tackle fuel poverty and household emissions.
Heat pumps
Heat pumps are described in the plan as the “best and cheapest form of electrified heating for the majority of our homes”.
The government’s goal is for heat pumps to “increasingly become the desirable and natural choice” for those replacing old boilers. At the same time, it says that new home standards will ensure that new-build homes have low-carbon heating systems installed by default.
Despite this, the warm homes plan scales back the previous government’s target for heat-pump installations in the coming years, reflecting the relatively slow increase in heat-pump sales. It also does not include a set date to end the sale of gas boilers.
The plan’s central target is for 450,000 heat pumps to be installed annually by 2030, including 200,000 in new-build homes and 250,000 in existing homes.
This is significantly lower than the previous target – originally set in 2021 under Boris Johnson’s Conservative government – to install 600,000 heat pumps annually by 2028.
Meeting that target would have meant installations increasing seven-fold in just four years, between 2024 and 2028. Now, installations only need to increase five-fold in six years.
As the chart below shows, the new target is also considerably lower than the heat-pump installation rate set out in the CCC’s central net-zero pathway. That involved 450,000 installations in existing homes alone by 2030 – excluding new-build properties.

Some experts and campaigners questioned how the UK would remain on track for its legally binding climate goals given this scaled-back rate of heat-pump installations.
Additionally, Adam Bell, policy director at the thinktank Stonehaven, writes on LinkedIn that the “headline numbers for heat pump installs do not stack up”.
Heat pumps in existing homes are set to be supported primarily via the boiler upgrade scheme and – according to Bell – there is not enough funding for the 250,000 installations that are planned, despite an increased budget.
The government’s plan relies in part on the up-front costs of heat pump installation “fall[ing] significantly”. According to Bell, it may be that the government will reduce the size of boiler upgrade scheme grants in the future, hoping that costs will fall sufficiently.
Alternatively, the government may rely on driving uptake through its planned low-cost loans and the clean heat market mechanism, which requires heating-system suppliers to sell a growing share of heat pumps.
Rooftop solar
Rooftop solar panels are highlighted in the plan as “central to cutting energy bills”, by allowing households to generate their own electricity to power their homes and sell it back to the grid.
At the same time, rooftop solar is expected to make a “significant contribution” to the government’s target of hitting 45-47 gigawatts (GW) of solar capacity by 2030.
As it stands, there is roughly 5.2GW of solar capacity on residential rooftops.
Taken together, the government says the grants and loans set out in the warm homes plan could triple the number of homes with rooftop solar from 1.6m to 4.6m by 2030.
It says that this is “in addition” to homes that decide to install rooftop solar independently.
Efficiency standards
The warm homes plan says that the government will publish its “future homes standard” for new-build properties, alongside necessary regulations, in the first quarter of 2026.
On the same day, the government also published its intention to reform “energy performance certificates” (EPCs), the ratings that are supposed to inform prospective buyers and renters about how much their new homes will cost to keep warm.
The current approach to measuring performance for EPCs is “unreliable” and thought to inadvertently discourage heat pumps. It has faced long-standing calls for reform.
As well as funding low-carbon technologies, the warm homes plan says it is “standing up for renters” with new energy-efficiency standards for privately and socially rented homes.
Currently, private renters – who rely on landlords to invest in home improvements – are the most likely to experience fuel poverty and to live in cold, damp homes.
Landlords will now need to upgrade their properties to meet EPC ratings B and C across two new-style EPC metrics by October 2030. There are “reasonable exemptions” to this rule that will limit the amount landlords have to spend per property to £10,000.
In total, the government expects “up to” 1.6m homes in the private-rental sector to benefit from these improvements and “up to” 1.3m social-rent homes.
These new efficiency standards therefore cover three-fifths of the “up to” 5m homes helped by the plan.
The government also published a separate fuel poverty strategy for England.
Heat networks
The warm homes plan sets out a new target to more than double the amount of heating provided using low-carbon heat networks – up to 7% of England’s heating demand by 2035 and a fifth by 2050.
This involves an injection of £1.1bn for heat networks, including £195m per year out to 2030 via the green heat network fund, as well as “mobilising” the National Wealth Fund.
The plan explains that this will primarily benefit urban centres, noting that heat networks are “well suited” to serving large, multi-occupancy buildings and those with limited space.
Alongside the plan, the government published a series of technical standards for heat networks, including for consumer protection.
What does the warm homes plan mean for energy bills?
The warm homes plan could save households “hundreds on energy bills” for those whose homes are upgraded, according to the UK government.
This is in addition to two changes announced in the budget in 2025, which are expected to cut energy bills for all homes by an average of £150 a year.
This included the decisions to bring ECO to an end when the current programme of work wraps up at the end of the financial year and for the treasury to cover three-quarters of the cost of the “renewables obligation” (RO) for three years from April 2026.
Beyond this, households that take advantage of the measures outlined in the plan can expect their energy bills to fall by varying amounts, the government says.
The warm homes plan includes a number of case studies that detail how upgrades could impact energy bills for a range of households. For example, it notes that a social-rented two-bedroom semi-detached home that got insulation and solar panels could save £350 annually.
An owner-occupier three-bedroom home could save £450 annually if it gets solar panels and a battery through consumer loans offered under the warm homes plan, it adds.
Similar analysis published by Nesta says that a typical household that invests in home upgrades under the plan could save £1,000 a year on its energy bill.
It finds that a household with a heat pump, solar panels and a battery, which uses a solar and “time of use tariff”, could see its annual energy bill fall by as much as £1,000 compared with continuing to use a gas boiler, from around £1,670 per year to £670, as shown in the chart below.

Ahead of the plan being published, there were rumours of further “rebalancing” energy bills to bring down the cost of electricity relative to gas. However, this idea failed to come to fruition in the warm homes plan.
This would have involved reducing or removing some or all of the policy costs currently funded via electricity bills, by shifting them onto gas bills or into general taxation.
This would have made it relatively cheaper to use electric technologies such as heat pumps, acting as a further incentive to adopt them.
Nesta highlights that in the absence of further action with regard to policy costs, the electricity-to-gas price ratio is likely to stay at around 4.1 from April 2026.
What has been the reaction to the plan?
Many of the commitments in the warm homes plan were welcomed by a broad range of energy industry experts, union representatives and thinktanks.
Greg Jackson, the founder of Octopus Energy, described it as a “really important step forward”, adding:
“Electrifying homes is the best way to cut bills for good and escape the yoyo of fossil fuel costs.”
Dhara Vyas, chief executive of the trade body Energy UK, said the government’s commitment to spend £15bn on upgrading home heating was “substantial” and would “provide certainty to investors and businesses in the energy market”.
On LinkedIn, Camilla Born, head of the campaign group Electrify Britain, said the plan was a “good step towards backing electrification as the future of Britain, but it must go hand in hand with bringing down the costs of electricity”.
However, right-leaning publications and politicians were critical of the plan, focusing on how a proportion of solar panels sold in the UK are manufactured in China.
According to BBC News, two-thirds (68%) of the solar panels imported to the UK came from China in 2024.
In an analysis of the plan, the Guardian’s environment editor Fiona Harvey and energy correspondent Jillian Ambrose argued that the strategy is “all carrot and no stick”, given that the “longstanding proposal” to ban the installation of gas boilers beyond 2035 has been “quietly dropped”.
Christopher Hammond, chief executive of UK100, a cross-party network of more than 120 local authorities, welcomed the plan, but urged the government to extend it to include public buildings.
The government’s £3.5bn public sector decarbonisation scheme, which aimed to electrify schools, hospitals and council buildings, ended in June 2025 and no replacement has been announced, according to the network.

Key developments
Tasks for 2026
‘GREEN RESOLVE’: The Ministry of Ecology and Environment (MEE) said at its annual national conference that it is “essential” to “maintain strategic resolve” on building a “beautiful China”, reported energy news outlet BJX News. Officials called for “accelerating green transformation” and “strengthening driving forces” for the low-carbon transition in 2026, it added. The meeting also underscored the need for “continued reduction in total emissions of major pollutants”, it said, as well as for “advancing source control through carbon peaking and a low-carbon transition”. The MEE listed seven key tasks for 2026 at the meeting, said business news outlet 21st Century Business Herald, including promoting development of “green productive forces”, focusing on “regional strategies” to build “green development hubs” and “actively responding” to climate change.
CARBON ‘PRESSURE’: China’s carbon emissions reduction strategy will move from the “preparatory stages” into a phase of “substantive” efforts in 2026, reported Shanghai-based news outlet the Paper, with local governments beginning to “feel the pressure” due to facing “formal carbon assessments for the first time” this year. Business news outlet 36Kr said that an “increasing number of industry participants” will have to begin finalising decarbonisation plans this year. The entry into force of the EU’s carbon border adjustment mechanism means China’s steelmakers will face a “critical test of cost, data and compliance”, reported finance news outlet Caixin. Carbon Brief asked several experts, including the Asia Society Policy Institute’s Li Shuo, what energy and climate developments they will be watching in 2026.
COAL DECLINE: New data released by the National Bureau of Statistics (NBS) showed China’s “mostly coal-based thermal power generation fell in 2025” for the first time in a decade, reported Reuters, to 6,290 terawatt-hours (TWh). The data confirmed earlier analysis for Carbon Brief that “coal power generation fell in both China and India in 2025”, marking the first simultaneous drop in 50 years. Energy news outlet International Energy Net noted that wind generation rose 10% to 1,053TWh and solar by 24% to 1,573TWh.

EV agreement reached
‘NORMALISED COMPETITION’?: The EU will remove tariffs on imports of electric vehicles (EV) made in China if the manufacturers follow “guidelines on minimum pricing” issued by the bloc, reported the Associated Press. China’s commerce ministry stated that the new guidelines will “enable Chinese exporters to address the EU’s anti-subsidy case concerning Chinese EVs in a way that is more practical, targeted and consistent with [World Trade Organization] rules”, according to the state-run China Daily. An editorial by the state-supporting Global Times argued that the agreement symbolised a “new phase” in China-EU economic and trade relations in which “normalised competition” is stabilised by a “solid cooperative foundation”.
SOLAR REBATES: China will “eliminate” export rebates for solar products from April 2026 and phase rebates for batteries out by 2027, said Caixin. Solar news outlet Solar Headlines said that the removal of rebates would “directly test” solar companies’ profitability and “fundamentally reshape the entire industry’s growth logic”. Meanwhile, China imposed anti-dumping duties on imports of “solar-grade polysilicon” from the US and Korea, said state news agency Xinhua.
OVERCAPACITY MEETINGS: The Chinese government “warned several producers of polysilicon…about monopoly risks” and cautioned them not to “coordinate on production capacity, sales volume and prices”, said Bloomberg. Reuters and China Daily covered similar government meetings on “mitigat[ing] risks of overcapacity” with the battery and EV industries, respectively. A widely republished article in the state-run Economic Daily said that to counter overcapacity, companies would need to reverse their “misaligned development logic” and shift from competing on “price and scale” to competing on “technology”.
High prices undermined home coal-to-gas heating policy
SWITCHING SHOCK: A video commentary by Xinhua reporter Liu Chang covered “reports of soaring [home] heating costs following coal-to-gas switching [policies] in some rural areas of north China”. Liu added that switching from coal to gas “must lead not only to blue skies, but also to warmth”. Bloomberg said that the “issue isn’t a lack of gas”, but the “result of a complex series of factors including price regulations, global energy shocks and strained local finances”.

HEATED DEBATE: Discussions of the story in China became a “domestically resonant – and politically awkward – debate”, noted the current affairs newsletter Pekingnology. It translated a report by Chinese outlet Economic Observer that many villagers in Hebei struggled with no access to affordable heating, with some turning back to coal. “Local authorities are steadily advancing energy supply,” People’s Daily said of the issue, noting that gas is “increasingly becoming a vital heating energy source” as part of China’s energy transition. Another People’s Daily article quoted one villager saying: “Coal-to-gas conversion is a beneficial initiative for both the nation and its people…Yet the heating costs are simply too high.”
DEJA-VU: This is not the first time coal-to-gas switching has encountered challenges, according to research by the Oxford Institute for Energy Studies, with nearby Shanxi province experiencing a similar situation. In Shanxi, a “lack of planning, poor coordination and hasty implementation” led to demand outstripping supply, while some households had their coal-based heating systems removed with no replacement secured. Others were “deterred” from using gas-based systems due to higher prices, it said.
More China news
- LOFTY WORDS: At Davos, vice-premier He Lifeng reaffirmed commitments to China’s “dual-carbon” goals and called for greater “global cooperation on climate change”, reported Caixin.
- NOT LOOKING: US president Donald Trump, also at Davos, said he was not “able to find any windfarms in China”, adding China sells them to “stupid” consumers, reported Euronews. China installed wind capacity has ranked first globally “for 15 years consecutively”, said a government official, according to CGTN.
- ‘GREEN’ FACTORIES: China issued “new guidelines to promote green [industrial] microgrids” including targets for on-site renewable use, said Xinhua. The country “pledged to advance zero-carbon factory development” from 2026, said another Xinhua report.
- JET-FUEL MERGER: A merger of oil giant Sinopec with the country’s main jet-fuel producer could “aid the aviation industry’s carbon reduction goals”, reported Yicai Global. However, Caixin noted that the move could “stifl[e] innovation” in the sustainable air fuel sector.
- NEW TARGETS: Chinese government investment funds will now be evaluated on the “annual carbon reduction rates” achieved by the enterprises or projects they support, reported BJX News.
- HOLIDAY CATCH-UP: Since the previous edition of China Briefing in December, Beijing released policies on provincial greenhouse gas inventories, the “two new” programme, clean coal benchmarks, corporate climate reporting, “green consumption” and hydrogen carbon credits. The National Energy Administration also held its annual work conference.
Spotlight
Why gas plays a minimal role in China’s climate strategy
While gas is seen in some countries as an important “bridging” fuel to move away from coal use, rapid electrification, uncompetitiveness and supply concerns have suppressed its share in China’s energy mix.
Carbon Brief explores the current role of gas in China and how this could change in the future. The full article is available on Carbon Brief’s website.
The current share of gas in China’s primary energy demand is small, at around 8-9%.
It also comprises 7% of China’s carbon dioxide (CO2) emissions from fuel combustion, adding 755m tonnes of CO2 in 2023 – twice the total CO2 emissions of the UK.
Gas consumption is continuing to grow in line with an overall uptick in total energy demand, but has slowed slightly from the 9% average annual rise in gas demand over the past decade – during which time consumption more than doubled.
The state-run oil and gas company China National Petroleum Corporation (CNPC) forecast in 2025 that demand growth for the year may slow further to just over 6%.
Chinese government officials frequently note that China is “rich in coal” and “short of gas”. Concerns of import dependence underpin China’s focus on coal for energy security.
However, Beijing sees electrification as a “clear energy security strategy” to both decarbonise and “reduce exposure to global fossil fuel markets”, said Michal Meidan, China energy research programme head at the Oxford Institute for Energy Studies.
A dim future?
Beijing initially aimed for gas to displace coal as part of a broader policy to tackle air pollution.
Its “blue-sky campaign” helped to accelerate gas use in the industrial and residential sectors. Several cities were mandated to curtail coal usage and switch to gas.
(January 2026 saw widespread reports of households choosing not to use gas heating installed during this campaign despite freezing temperatures, due to high prices.)
Industry remains the largest gas user in China, with “city gas” second. Power generation is a distant third.
The share of gas in power generation remains at 4%, while wind and solar’s share has soared to 22%, Yu Aiqun, research analyst at the thinktank Global Energy Monitor, told Carbon Brief. She added:
“With the rapid expansion of renewables and ongoing geopolitical uncertainties, I don’t foresee a bright future for gas power.”
However, gas capacity may still rise from 150 gigawatts (GW) in 2025 to 200GW by 2030. A government report noted that gas will continue to play a “critical role” in “peak shaving”.
But China’s current gas storage capacity is “insufficient”, according to CNPC, limiting its ability to meet peak-shaving demand.
Transport and industry
Gas instead may play a bigger role in the displacement of diesel in the transport sector, due to the higher cost competitiveness of LNG – particularly for trucking.
CNPC forecast that LNG displaced around 28-30m tonnes of diesel in the trucking sector in 2025, accounting for 15% of total diesel demand in China.
However, gas is not necessarily a better option for heavy-duty, long-haul transportation, due to poorer fuel efficiency compared with electric vehicles.
In fact, “new-energy vehicles” are displacing both LNG-fueled trucks and diesel heavy-duty vehicles (HDVs).
Meanwhile, gas could play a “more significant” role in industrial decarbonisation, Meidan told Carbon Brief, if prices fall substantially.
Growth in gas demand has been decelerating in some industries, but China may adopt policies more favourable to gas, she added.

Both will be significantly less important than clean-energy sources at that point.
