China’s thinking around the energy transition shifted drastically in 2020 after president Xi Jinping pledged to reach carbon neutrality before 2060.
Despite a series of major policy developments since then, however, it is still not clear what the new energy system will look like and which pathways are the most efficient for China to reach its carbon neutrality goal.
Our latest research models three scenarios for China’s energy transition: one in which China develops a net-zero emissions energy system before 2055; one in which it achieves this around 2055; and a baseline scenario that extrapolates current development trends.
We find that a combination of energy efficiency measures, electrification of end-use consumption and a low-carbon power supply based on various renewable energy sources – such as solar and wind – can greatly help the country to achieve its decarbonisation goals by 2055.
In the most ambitious scenario, China’s power sector will be fossil fuel-free by 2055, while some industries will continue to use a small amount of coal and gas. However, this will be balanced by negative emissions from biomass power plants fitted with carbon capture and storage (BECCS).

How the dual carbon targets changed the game
When Xi began his speech at the UN General Assembly in September 2020, few had expected him to deliver such a ground-breaking announcement.
In his words: “We aim to have CO2 [carbon dioxide] emissions peak before 2030 and achieve carbon neutrality before 2060.”
This policy is now more commonly known as the “dual carbon” goals.
That one sentence changed the whole understanding of the energy transformation in China.
Until then, China’s target was to “promote a revolution in energy production and consumption, and build an energy sector that is clean, low-carbon, safe and efficient”, as Xi had said at the 19th National Congress of the Communist Party in China (CPC) in October 2017.
Xi’s 2020 speech shifted China’s priorities from reaching “low-carbon” to reaching “carbon neutrality”, from an energy sector that includes at least some fossil fuel consumption, to an energy sector which leaves little room for coal, oil and gas once carbon neutrality is reached.
The difference required a genuine change of mindset throughout China’s political system and stakeholders within the energy system, such as major power producers.
China started this immediately after the announcement: the State Council, China’s top administrative body, introduced the 1+N policy strategy, which is comprised of an overarching guideline for reaching the “dual carbon” goals (the “1”) and a number of more concrete guidelines and regulations to implement the strategy (the “N”).
So far, the policies have mainly focused on reaching the carbon peak before 2030 – but the long-term goal of carbon neutrality by 2060 is ever-present.
The National Energy Administration (NEA) has launched a blueprint for a new type of power system. At a broader level, several government departments have outlined efforts to transform the entire energy system, as opposed to just the power system, in the effort to reach carbon neutrality.
Hence, the foundation for China’s energy transformation is much more solid and precise today than it was before Xi’s announcement. The question now is: what will the new type of energy system look like and how will China reach it?
Three scenarios for China’s energy transformation
To answer these questions, our programme modelled three scenarios for China’s energy transformation: one in which China develops a net-zero emissions energy system before 2055; one in which it achieves this around 2055; and a baseline scenario that extrapolates current development trends.
The analysis is based on a detailed bottom-up modelling approach, while, at the same time, using visions for a “Beautiful China” – an official initiative for “the nation’s green and high-quality growth” – as guidelines for the transformation.
In our modelling, the overarching strategy for the energy transformation consists of three intertwined actions:
- Increase energy efficiency throughout the supply chain.
- Electrify the end-use sectors as much as possible.
- Transform the power sector into a “green”, fossil-free sector with solar and wind power as the backbone of the system.
(The Intergovernmental Panel on Climate Change’s latest assessment report showed that these are key elements of all global pathways that limit warming to 1.5C or 2C.)
A consequence of following this strategy would be that the Chinese energy system would be able to provide energy for sustainable economic growth in China with net-zero carbon emissions, improved air quality and a high level of energy security.
In the most ambitious scenario, the Chinese power system would be carbon-neutral from 2045 – and the whole energy system before 2055.
Compared to today, total primary energy consumption would be lower in 2060 despite economic growth. Moreover, coal, oil and gas would be practically phased out of the system – and dependence on imported fossil fuels would be eliminated.
The figure below shows the energy flowing through China’s economy in 2021 (upper panel) compared with the energy flow in 2060 under this most ambitious scenario (lower panel).
On the left, each panel shows sources of primary energy flowing into the economy such as coal (black), gas (pink), oil (shades of grey) and non-fossil fuels such as nuclear (brown), hydro (dark blue), wind (light blue) and solar (yellow).
The centre of each panel illustrates the transformation of primary energy into more useful forms, such as electricity or refined oil products. Much of the primary energy contained in fossil fuels is wasted at this stage (“losses”) in the form of waste heat.
On the right, the users of final energy are broken down by sector.
Most notably, fossil fuels – particularly coal – are the largest sources of energy in 2021, whereas in the ambitious 2060 scenario, below, low-carbon sources dominate.
Three phases in China’s energy transformation
Our study suggests the transformation pathway will have three main phases. The first phase is the peaking phase until 2030.
During this period, the deployment of wind and solar power would continue to increase, while electrification of the industry and transport sectors would gain momentum.
However, coal and oil would remain the dominant energy sources in terms of total primary energy consumption.
Next is the “energy revolution” phase, from 2030 to 2050. During this phase, solar and wind power would become the main energy sources for electricity supply, and the electrification of the end-use sectors would be substantial.
The shift away from fossil fuels minimises the loss of waste heat in electricity generation and refining. Meanwhile, “green hydrogen” made from renewable power would become increasingly important in the industrial sectors.
The third phase is the consolidation phase, from 2050 to 2060. Decarbonisation occurs in sub-sectors that are challenging to electrify, such as the steel and chemicals industries, the old solar and wind power plants are replaced by new solar and wind power, and remaining fossil fuels in the energy mix are nearly phased out.
Coal power plants become flexibility providers
Although the Chinese government plans to “phase down” coal from 2025, based on the current policy guidelines and market situation, we estimate that coal power capacity would not be rapidly removed in any of our three scenarios.
Instead, coal power plants would gradually become providers of energy security and capacity to meet peaks in electricity demand, and not generate large amounts of electricity.
By the time they reach the end of their expected lifetime of around 30 years, the plants would be shut down and not replaced with new coal capacity. In our most ambitious scenario, the last coal power plants are closed in 2055, as shown in the figure below.
The upper panel in the figure shows the installed capacity of coal power plants and the lower panel their electricity production from 2021 to 2060.
Meanwhile, gas does not play a significant role in the power sector in our scenarios, as solar and wind can provide cheaper electricity while existing coal power plants – together with scaled-up expansion of energy storage and demand-side response facilities – can provide sufficient flexibility and peak-load capacity.
Managing a grid dominated by variable wind and solar
An energy system that relies on solar and wind power as main suppliers of power requires special flexibility measures to match production and demand.
The figure below shows a modelled example of an hourly electricity balance in a week in the summer of 2060 under our more ambitious scenario of achieving carbon neutrality before 2055.
The top panel shows electricity production on the supply side. In the daytime solar power (yellow) dominates the production of electricity, while wind power plants (light blue) have a more stable output throughout the 24-hour period.
In the evening and at night, electricity storage is discharged (purple) and hydropower production (dark blue) is higher than in the daytime.
The lower panel shows electricity use on the demand side. Storage (purple) is charged in the daytime and electric vehicle (EV) smart charging (blue) provides flexibility throughout the week.
As a backup, vehicle-to-grid supply plays an important role – not necessarily as a significant energy provider but as a last-resort capacity that can be activated if necessary, when wind and solar output is low. This solution is a cheap and efficient way to ensure sufficient capacity in the power system.
Before 2055, coal power plants could be equally reliable and affordable providers of capacity for the power system, even though they would not generate much electricity on average, as mentioned earlier.
This way of creating flexibility might seem complicated to manage in terms of daily dispatch (the process of managing supply and demand). However, an efficient and well-functioning electricity market, including consumers and producers, can do the job.
Removing the barriers to electricity trading among provinces and constructing a unified national electricity market would be a key enabler of this.
Visions for the future
The scenarios from our China Energy Transformation Outlook give a range of quantified visions of the long-term future in a net-zero energy system.
Our detailed model of the power system and other energy end-use sectors make it possible to link the development of this new energy system with policy measures that could bring about this transformation.
One key insight from our work relates to the timing of the different phases of China’s energy transformation, mentioned above. Our modelling suggests that successful coordination of these phases will be crucial, in order to maintain energy security while avoiding unnecessary investments in energy infrastructure.
Other key enablers in our scenarios are the investments needed to expand the electricity grid, the development of a national electricity market and support for energy system flexibility.
Even with the best visions, and insights from pathways such as ours, there will be many challenges and barriers ahead to overcome if China is to reach its 2060 goal.
Our scenarios show, however, that there are feasible and cost-efficient pathways which can be implemented without waiting for new technological breakthroughs.

The governor’s office said the city’s two main reservoirs could dry up by May, much sooner than previous timelines. But authorities still offer no plan for curtailment of water use.
City officials in Corpus Christi on Tuesday released modeling that showed emergency cuts to water demand could be required as soon as May as reservoir levels continue to decline.

As toxic clouds loom over Tehran and Beirut from the US and Israel’s bombardment of oil depots and civilian infrastructure in the region’s ongoing war, the world is once again witnessing the not-so-subtle connections between conflict, hunger, food insecurity and the vulnerability of global food systems dependent on fossil fuels, dominated by a few powerful countries and corporations.
The conflict in Iran is having a huge impact on the world’s fertilizer supply. The Strait of Hormuz is a critical trade route in the region for nearly half of the global supply of urea, the main synthetic fertilizer derived from natural gas through the conversion of ammonia.
With the Strait impacted by Iran’s blockades, prices of urea have shot up by 35% since the war started, just as planting season starts in many parts of the world, putting millions of farmers and consumers at risk of increasing production costs and food price spikes, resulting in food insecurity, particularly for low-income households. The World Food Programme has projected that an extra 45 million people would be pushed into acute hunger because of rises in food, oil and shipping costs, if the war continues until June.
Pesticides and synthetic fertilizer leave system fragile
On the face of it, this looks like a supply chain issue, but at the core of this crisis lies a truth about many of our food systems around the world: the instability and injustice in the very design of systems so reliant on these fossil fuel inputs for our food.
At the Global Alliance, a strategic alliance of philanthropic foundations working to transform food systems, we have been documenting the fossil fuel-food nexus, raising alarm about the fragility of a system propped up by fossil fuels, with 15% of annual fossil fuel use going into food systems, in part because of high-cost, fossil fuel-based inputs like pesticides and synthetic fertilizer. The Heinrich Böll Foundation has also been flagging this threat consistently, most recently in the Pesticide Atlas and Soil Atlas compendia.
We’ve seen this before: Russia’s invasion of Ukraine in 2022 sparked global disruptions in fertilizer supply and food price volatility. As the conflict worsened, fertilizer prices spiked – as much from input companies capitalizing on the crisis for speculation as from real cost increases from production and transport – triggering a food price crisis around the world.

Since then, fertilizer industry profit margins have continued to soar. In 2022, the largest nine fertilizer producers increased their profit margins by more than 35% compared to the year before—when fertilizer prices were already high. As Lena Bassermann and Dr. Gideon Tups underscore in the Heinrich Böll Foundation’s Soil Atlas, the global dependencies of nitrogen fertilizer impacted economies around the world, especially state budgets in already indebted and import-dependent economies, as well as farmers across Africa.
Learning lessons from the war in Ukraine, many countries invested heavily in renewable energy and/or increased domestic oil production as a way to decrease dependency on foreign fossil fuels. But few took the same approach to reimagining domestic food systems and their food sovereignty.
Agroecology as an alternative
There is another way. Governments can adopt policy frameworks to encourage reductions in synthetic fertilizer and pesticide use, especially in regions that currently massively overuse nitrogen fertilizer. At the African Union fertilizer and Soil Health Summit in 2024, African leaders at least agreed that organic fertilizers should be subsidized as well, not only mineral fertilizers, but we can go farther in actively promoting agricultural pathways that reduce fossil fuel dependency.
In 2024, the Global Alliance organized dozens of philanthropies to call for a tenfold increase in investments to help farmers transition from fossil fuel dependency towards agroecological approaches that prioritize livelihoods, health, climate, and biodiversity.
In our research, we detail the huge opportunity to repurpose harmful subsidies currently supporting inputs like synthetic fertilizer and pesticides towards locally-sourced bio-inputs and biofertilizer production. We know this works: There are powerful stories of hope and change from those who have made this transition, despite only receiving a fraction of the financing that industrial agriculture receives, with evidence of benefits from stable incomes and livelihoods to better health and climate outcomes.
New summit in Colombia seeks to revive stalled UN talks on fossil fuel transition
Inspiring examples abound: G-BIACK in Kenya is training farmers how to produce their own high-quality compost; start-ups like the Evola Company in Cambodia are producing both nutrient-rich organic fertilizer and protein-rich animal feed with black soldier fly farming; Sabon Sake in Ghana is enriching sugarcane bagasse – usually organic waste – with microbial agents and earthworms to turn it into a rich vermicompost.
These efforts, grounded in ecosystems and tapping nature for soil fertility and to manage pest pressures, are just some of the countless examples around the world, tapping the skill and knowledge of millions of farmers. On a national and global policy level, the Agroecology Coalition, with 480+ members, including governments, civil society organizations, academic institutions, and philanthropic foundations, is supporting a transition toward agroecology, working with natural systems to produce abundant food, boost biodiversity, and foster community well-being.
Fertilizer industry spins “clean” products
We must also inoculate ourselves from the fertilizer industry’s public relations spin, which includes promoting the promise that their products can be produced without heavy reliance on fossil fuels. Despite experts debunking the viability of what the industry has dubbed “green hydrogen” or “green or clean ammonia”, the sector still promotes this narrative, arguing that these are produced with resource-intensive renewable energy or Carbon Capture and Storage (CCS), a costly and unreliable technology for reducing emissions.
As we mourn this conflict’s senseless destruction and death, including hundreds of children, we also recognize that peace cannot mean a return to business-as-usual. We need to upend the systems that allow the richest and most powerful to have dominion over so much.
This includes fighting for a food system that is based on genuine sovereignty and justice, free from dependency on fossil fuels, one that honors natural systems and puts power into the hands of communities and food producers themselves.
