Key developments
China’s top climate negotiator interviewed
COAL STANCE: China News Weekly recently interviewed Su Wei, China’s lead climate negotiator, about China’s stance at COP28 and its energy transition. Su affirmed China’s position on fossil fuels, saying that it is “impossible to completely phase out fossil fuels, given limitations of the resources China possesses”. He argued that countries did not have to “be utterly opposed” to fossil fuels as long as the central question of emissions is solved, through technologies such as carbon capture, utilisation and storage (CCUS). Substituting fossil fuels with renewable energy should follow the principle of “establish [new rules] before breaking [old ones]”, he added. This means a “process” needs to be followed – namely, after “large-scale development” of renewable energy and non-fossil fuel energy, “coal power will be gradually reduced and the proportion of coal stock will also decline”.
DEVELOPED VS DEVELOPING: Su also highlighted the role of developed countries as a key debate at COP28. He described the current international environment as the “biggest challenge to realising the goal of tripling renewable energy capacity globally”, with some developed countries imposing tariffs on or launching investigations into Chinese products. He also criticised developed countries’ failure to provide the $100bn in climate finance they committed to in 2009, describing it as a “muddled account”.
US-CHINA OPTIMISM: Nevertheless, Su was relatively optimistic about the potential for US-China climate cooperation. He raised how US-China alignment at COP28 “made an important contribution” to its success, with the Sunnylands statement jointly released by the two countries allowing them to “propose wording for the text and help[ing] to unlock difficult issues in the negotiation”. Climate change, Su said, “remains one of the few positive elements that China and the US can mobilise to promote the stable development of their relationship”, allowing the two countries to “talk” despite other tensions. (In a recent issue of the Pekingnology newsletter, noted international relations scholar Da Wei concurred, saying the US and China “have some agreements on the climate change issue”. He added: “I believe that the two sides will declare more on climate change in the following months.”)
China ‘needs 324tn yuan’ to meet climate goals
‘ENORMOUS AMOUNT’: China needs to “spend about 324tn yuan” ($45.5tn), which is equal to 2.7 times its 2022 GDP, between 2021 and 2060 to achieve its goals of peaking carbon emissions by 2030 and reaching carbon neutrality by 2060, reported state-run newspaper the China Daily. The figures were included in China’s fourth national communication on climate change, which was submitted to the United Nations Framework Convention on Climate Change in December 2023. China “will need to spend far more to reach carbon neutrality than to achieve carbon peaking”, the document added. China’s previous national communication was submitted more than four years ago in 2019.
GROWING INVESTMENT: Meanwhile, China’s annual national economic work conference – held in December 2023 – announced “promotion of…green and low-carbon development” as one of nine key economic tasks in 2024, with “green” development becoming the “driving force for China’s high-quality development”, according to China News. The 2024 national energy work conference, also held in December, established that China aims to build 200 gigawatts (GW) of wind and solar capacity in 2024, as well as 5GW of nuclear energy, the newspaper added. China5E reported that China’s top economic planner, the national development and reform commission (NDRC) said in its first meeting of 2024 that it would develop “tangible policies” to attract private capital to invest in nuclear power and other major energy projects, as well as environmental protection schemes. Investment in renewable energy in China “seems increasingly to be driven by the profit motive”, a Financial Times editorial argued, adding that this trend is accelerated by increasing adoption of “cleantech” by China’s state-owned enterprises.
MARKET FORCES: China is also developing financial platforms to boost “green” and low-carbon investment in the new year. On 2 January, it launched a stock index to encourage “investment products that grant greater weightings for sectors such as renewables”, reported the Financial Times. Meanwhile, should China’s voluntary carbon market, the China Certified Emissions Reduction (CCER) program, relaunch this year, it could encourage finance to flow to projects that, together, could reduce carbon emissions by tens or even hundreds of millions of tonnes, Jiemian noted.
Updated industry guidelines to ‘encourage green tech’
INDUSTRY CATALOGUE: China’s top economic planner, the national development and reform commission (NDRC), released an updated 2024 version of its catalogue for guiding industry restructuring, designed to “promote high-end, intelligent and green manufacturing”, Xinhua reported. The catalogue divides industries into three categories: encouraged; restricted; and eliminated, reported China Environment. The “restricted” category refers to technologies, equipment and products that, among other things, “are not conducive to the realisation of the goals of carbon peaking and carbon neutrality”, it explained. The “eliminated” category contains technologies that “seriously waste resources, cause pollution…[or] impede the realisation of the goals of carbon peaking and carbon neutrality”, the outlet added. China Environment also reported that the catalogue said it would “encourage green technology innovation and the development of green environmental protection industry, promote energy saving…and resolutely curb the blind development of high-energy-consuming, high-emission and low-level projects”. (The phrase on curbing “blind development” has been in use for several years.)
NEW ADDITIONS: The “encouraged” category adds a “detailed explanation of carbon capture and application”, reported BJX News. The category also adds “green” hydrogen produced by electrolysis of water and synthesis of “green methanol” from carbon dioxide, as well as new solar materials for use in the construction industry, reported the news outlet. The “restricted” category has raised and added limitations for the power sector, such as new coal power units that cannot meet “ultra-low emission” requirements, said the report. Under the “elimination” category, thermal power plants will be phased out in accordance with the principle of “establish first, then modify” (先立后改) with plants eliminated “in an orderly manner, in accordance with an “annual phase-out plan”, added the report. The least efficient coal-fired boilers will be phased out in air pollution priority areas, the outlet added.
OFFICIAL REACTION: Officials from the NDRC told Jiemian that the new edition of the catalogue aims to promote “high-end, intelligent, and green manufacturing industry” in China, they added. The updated catalogue “will encourage green technology innovation and the development of green environmental protection industries, promote energy conservation, carbon reduction and green transformation in key areas”, they told the outlet.
BYD surpassed Tesla, claiming the top spot in EV sales
BYD VS TESLA: Chinese firm BYD’s sales of battery-only vehicles “outpaced” its US rival Tesla in the final quarter of 2023 for the first time, according to BBC News. BYD sold 526,000 units while Tesla delivered 484,000 units. However, for the whole of 2023, Tesla still sold more with 1.8m compared to nearly 1.6m for BYD, the broadcaster added.
SUCCESS STORY: CNN said that China’s fast transition to electric vehicles (EVs) is “thanks to strong government support”. The article quoted analysts from investment bank Natixis Asia saying “first-mover advantage and government support through infrastructure investment and subsidies have made it easy for Chinese EV makers to expand domestically and internationally”. (Consultant David Fishman noted on Twitter that domestic EV sales grew by 36% in 2023, “despite the end of the supporting subsidies”.) According to Bernstein research, “BYD batteries are among the lowest cost in the world”, reported the Financial Times. Michael Dunne, chief executive of Asia-focused car consultancy Dunne Insights, told the FT: “No one can match BYD on price. Period.” In his Bloomberg column, David Fickling attributed BYD’s edge to its in-house battery supply chain and cheaper cells. “More importantly”, he said, “on almost every financial metric, [BYD] is either advancing on, or overtaking [Tesla] — with its gaze already set on the wider car industry.”
FORECAST FOR 2024: Looking ahead to this year, S&P Global Mobility predicted battery electric vehicles (BEVs) sales would reach 13.3m units globally in 2024, accounting for 16.2% of total global passenger vehicle sales, with China’s BEV sales growing 28.6% year-on-year. BloombergNEF’s outlook forecast a milestone will be achieved by the end of 2024 – it will see the first quarter in which consumers buy more than five million electric or plug-in hybrid vehicles, with China being the main contributor.
Spotlight
What to watch in 2024
In 2023, several significant energy and climate stories came out of China. Global carbon dioxide (CO2) emissions rose, driven by increases in China, but analysis for Carbon Brief found that renewable energy growth could cause a “structural decline” of emissions from 2024. New coal “capacity payments” continue policy support for the fuel.
Meanwhile, the US and China issued the Sunnylands statement, which signalled a turning point in bilateral relations and played a part in theCOP28 outcome.
For the first China Briefing of 2024, Carbon Brief asks leading experts what they are watching for in China in the year ahead. Responses have been edited for length and clarity.
Joanna Lewis, provost’s distinguished associate professor of energy and environment, and director of the science, technology and international affairs program, Georgetown University:
The key thing I will be watching is the development of China’s new nationally determined contribution (NDC) and associated 2035 climate goals. Given the Sunnylands statement and COP28 decisions, we can expect that China’s next NDC will include the country’s first economy-wide target covering all greenhouse gases. As China’s emissions are slated to peak before 2030, it will also likely be China’s first absolute emissions target.
Beyond the NDC, I will also be watching China’s coal consumption. While consumption increased in 2023, many predict a slowing in 2024 and possible peaking by 2025 (or earlier). So watching trends over the coming year may signal what is to come. Also important to determining coal trends will be the rate of renewable energy growth. With an estimated 230GW of new wind and solar power installed in China last year – twice that of the US and Europe combined – and major advances in energy storage that are helping address the curtailment issue, China’s renewables sector is poised for continued rapid growth, which can help offset the demand for coal in the power sector.
David Fishman, senior manager, the Lantau Group:
China spent 2023 implementing incremental reforms to its power sector and energy policy – still trending in the right direction for power market decarbonisation and liberalisation, but taking smaller steps than in the previous few years. This is a return to normalcy for China, which has typically adopted a measured approach to policy reforms: preferring to make small changes and observe the outcomes of limited pilots, rather than big changes all at once.
I expect 2024 to be more of the same, with spot-trading in the power exchanges becoming more common and renewable consumption quotas expanding to more sectors. At the same time, the surging growth in renewable capacity, especially from desert mega-bases, should allow renewable generation growth to exceed power consumption growth. This will cap coal consumption in the power sector and send China’s carbon emissions into long-term structural decline from 2024 onward.
Ryna Cui, research director, Center for Global Sustainability, University of Maryland:
It is crucial to watch how coal plants will be utilised in the power system, whether as expected to back up an increasing share of intermittent renewables or to continue as “baseload” generation, where the emissions impact can be significant. It is also critical to watch whether and how China moves from a continued preference for coal to other solutions for grid stabilisation, such as cross-region grid balancing, demand-side management, battery and other storage technologies.
Methane is an emerging area that is finally receiving the policy attention it requires – both in China and globally. China’s methane action plan is the first published national policy targeting methane as a greenhouse gas (GHG). The document is brief, setting up overall guidelines and main task areas. So it is important to watch how more detailed policies and targets will continue to develop.
Internationally, the US-China Sunnylands statement set up the expectation for the next round of NDCs to cover all GHGs and all economic sectors. It will be exciting to watch how Sunnylands and the previous joint Glasgow declaration will be implemented.
Yan Qin, lead carbon analyst at the London Stock Exchange Group:
This will be an exciting year for China’s national carbon market and the newly relaunched offset market. The national emissions trading scheme (ETS) has just completed its second compliance period, with allowance prices rising to as high as 80 yuan per tonne ($11.25/t) due to tightening of benchmarks.
The scheme will see more progress this year, both on the regulatory side, with the newly released state council regulation on national carbon trading, and on the expansion to more industry sectors, with the first new batch possibly including the cement and aluminium sectors. We might also see more clarity on the role of the carbon market in China’s “dual carbon” targets against the backdrop of moving from energy dual control to carbon dual control. The revamped China Certified Emissions Reduction (CCER) offset market will also see issuance of new credits resume this year.
Tu Le, founder and managing director, Sino Auto Insights:
It was another record year for “new energy vehicle” (NEV, mainly electric vehicle) sales in China, largely on the back of a serious price war ignited by Tesla in January 2023. I’ll be watching to see whether the market can keep it up – and who will blink first this year. Will there continue to be foreign direct investment by Chinese electric vehicle and battery companies outside of China and, if so, where?
Chinese automakers exported a record number of vehicles in 2023, catching many observers’ attention. With the Inflation Reduction Act making the US market unattractive for now, the EU is the most attractive major market to Chinese EV firms. EU automakers will also begin shipping Chinese-built vehicles to their home markets. How the EU will ultimately react to this – and the growth of Chinese EV exports more widely – remains uncertain.
Watch, read, listen
BIG READ: China submitted its fourth national communication on climate change to the UNFCCC in December 2023 – the first since June 2019 – with sections on China’s greenhouse gas emissions by sector, “key objectives” and financial needs.
DE-RISKING RISKS: Henry Sanderson argued in Foreign Affairs that western countries must prioritise in order to compete with China on “clean energy” technologies.
WASTE UNREST: The New Books in East Asian Studies podcast interviewed Dr Jean Yen-chun Lin on research into environmental protests against waste incineration in Beijing.
CLIMATE ADAPTATION: China and Africa will “jointly promote climate resilience”, ministry of ecology and environment minister Huang Runqiu said in remarks, recently posted on YouTube, made at the September 2023 Africa Climate Summit.
New science
Hotter days, dirtier air: The impact of extreme heat on energy and pollution intensity in China
Energy Economics
Researchers have identified a “causal impact from ‘local temperature shocks’ on pollution intensity” in China between 2008 and 2017, finding that extreme heat increases energy demand, diminishes energy efficiency and increases consumption of coal, which leads to a rise in pollution intensity. The researchers said that this shows that extreme weather caused by climate change “will perpetuate an adverse impact on pollution intensity” across China.
Methane mitigation potentials and related costs of China’s coal mines
Fundamental Research
A new study estimated that “through continuous coal cuts and available…mitigation measures, China’s [coal mine methane] emissions can be reduced by 65%-78% [from 2021 levels] in 2060”. The study also found that methane emissions from abandoned coal mines “will far exceed those from coal mining under the 2060 carbon-neutral scenario, especially in northeastern China”. While coal mine methane mitigation may not currently be economically feasible, it added, it could become “the most cost-effective solution as [carbon dioxide] prices increase”.
Who is most affected by carbon tax? Evidence from Chinese residents in the context of ageing
Energy Policy
New research has discovered “significant differences” in the rate by which different age groups in China are affected by carbon taxation, with the “vulnerable elderly” being particularly affected. The results show that the “indirect carbon payment burden rate on the elderly…is 1.2 times that of the general population”, with low-income seniors facing a slightly higher than average rate at 1.4 times that of the general population.

Efforts to green lithium extraction face scrutiny over water use
Mining companies are showcasing new technologies which they say could extract more lithium – a key ingredient for electric vehicle (EV) batteries – from South America’s vast, dry salt flats with lower environmental impacts.
But environmentalists question whether the expensive technology is ready to be rolled out at scale, while scientists warn it could worsen the depletion of scarce freshwater resources in the region and say more research is needed.
The “lithium triangle” – an area spanning Argentina, Bolivia and Chile – holds more than half of the world’s known lithium reserves. Here, lithium is found in salty brine beneath the region’s salt flats, which are among some of the driest places on Earth.
Lithium mining in the region has soared, driven by booming demand to manufacture batteries for EVs and large-scale energy storage.
Mining companies drill into the flats and pump the mineral-rich brine to the surface, where it is left under the sun in giant evaporation pools for 18 months until the lithium is concentrated enough to be extracted.
The technique is relatively cheap but requires vast amounts of land and water. More than 90% of the brine’s original water content is lost to evaporation and freshwater is needed at different stages of the process.
One study suggested that the Atacama Salt Flat in Chile is sinking by up to 2 centimetres a year because lithium-rich brine is being pumped at a faster rate than aquifers are being recharged.
Lithium extraction in the region has led to repeated conflicts with local communities, who fear the impact of the industry on local water supplies and the region’s fragile ecosystem.
The lithium industry’s answer is direct lithium extraction (DLE), a group of technologies that selectively extracts the silvery metal from brine without the need for vast open-air evaporation ponds. DLE, it argues, can reduce both land and water use.
Direct lithium extraction investment is growing
The technology is gaining considerable attention from mining companies, investors and governments as a way to reduce the industry’s environmental impacts while recovering more lithium from brine.
DLE investment is expected to grow at twice the pace of the lithium market at large, according to research firm IDTechX.
There are around a dozen DLE projects at different stages of development across South America. The Chilean government has made it a central pillar of its latest National Lithium Strategy, mandating its use in new mining projects.
Last year, French company Eramet opened Centenario Ratones in northern Argentina, the first plant in the world to attempt to extract lithium solely using DLE.
Eramet’s lithium extraction plant is widely seen as a major test of the technology. “Everyone is on the edge of their seats to see how this progresses,” said Federico Gay, a lithium analyst at Benchmark Mineral Intelligence. “If they prove to be successful, I’m sure more capital will venture into the DLE space,” he said.
More than 70 different technologies are classified as DLE. Brine is still extracted from the salt flats but is separated from the lithium using chemical compounds or sieve-like membranes before being reinjected underground.
DLE techniques have been used commercially since 1996, but only as part of a hybrid model still involving evaporation pools. Of the four plants in production making partial use of DLE, one is in Argentina and three are in China.
Reduced environmental footprint
New-generation DLE technologies have been hailed as “potentially game-changing” for addressing some of the issues of traditional brine extraction.
“DLE could potentially have a transformative impact on lithium production,” the International Lithium Association found in a recent report on the technology.
Firstly, there is no need for evaporation pools – some of which cover an area equivalent to the size of 3,000 football pitches.
“The land impact is minimal, compared to evaporation where it’s huge,” said Gay.


The process is also significantly quicker and increases lithium recovery. Roughly half of the lithium is lost during evaporation, whereas DLE can recover more than 90% of the metal in the brine.
In addition, the brine can be reinjected into the salt flats, although this is a complicated process that needs to be carefully handled to avoid damaging their hydrological balance.
However, Gay said the commissioning of a DLE plant is currently several times more expensive than a traditional lithium brine extraction plant.
“In theory it works, but in practice we only have a few examples,” Gay said. “Most of these companies are promising to break the cost curve and ramp up indefinitely. I think in the next two years it’s time to actually fulfill some of those promises.”
Freshwater concerns
However, concerns over the use of freshwater persist.
Although DLE doesn’t require the evaporation of brine water, it often needs more freshwater to clean or cool equipment.
A 2023 study published in the journal Nature reviewed 57 articles on DLE that analysed freshwater consumption. A quarter of the articles reported significantly higher use of freshwater than conventional lithium brine mining – more than 10 times higher in some cases.
“These volumes of freshwater are not available in the vicinity of [salt flats] and would even pose problems around less-arid geothermal resources,” the study found.
The company tracking energy transition minerals back to the mines
Dan Corkran, a hydrologist at the University of Massachusetts, recently published research showing that the pumping of freshwater from the salt flats had a much higher impact on local wetland ecosystems than the pumping of salty brine. “The two cannot be considered equivalent in a water footprint calculation,” he said, explaining that doing so would “obscure the true impact” of lithium extraction.
Newer DLE processes are “claiming to require little-to-no freshwater”, he added, but the impact of these technologies is yet to be thoroughly analysed.
Dried-up rivers
Last week, Indigenous communities from across South America held a summit to discuss their concerns over ongoing lithium extraction.
The meeting, organised by the Andean Wetlands Alliance, coincided with the 14th International Lithium Seminar, which brought together industry players and politicians from Argentina and beyond.
Indigenous representatives visited the nearby Hombre Muerto Salt Flat, which has borne the brunt of nearly three decades of lithium extraction. Today, a lithium plant there uses a hybrid approach including DLE and evaporation pools.
Local people say the river “dried up” in the years after the mine opened. Corkran’s study linked a 90% reduction in wetland vegetation to the lithium’s plant freshwater extraction.
Pia Marchegiani, of Argentine environmental NGO FARN, said that while DLE is being promoted by companies as a “better” technique for extraction, freshwater use remained unclear. “There are many open questions,” she said.
AI and satellite data help researchers map world’s transition minerals rush
Stronger regulations
Analysts speaking to Climate Home News have also questioned the commercial readiness of the technology.
Eramet was forced to downgrade its production projections at its DLE plant earlier this year, blaming the late commissioning of a crucial component.
Climate Home News asked Eramet for the water footprint of its DLE plant and whether its calculations excluded brine, but it did not respond.
For Eduardo Gigante, an Argentina-based lithium consultant, DLE is a “very promising technology”. But beyond the hype, it is not yet ready for large-scale deployment, he said.
Strong regulations are needed to ensure that the environmental impact of the lithium rush is taken seriously, Gigante added.
In Argentina alone, there are currently 38 proposals for new lithium mines. At least two-thirds are expected to use DLE. “If you extract a lot of water without control, this is a problem,” said Gigante. “You need strong regulations, a strong government in order to control this.”

Maryland’s Conowingo Dam Settlement Reasserts State’s Clean Water Act Authority but Revives Dredging Debate
The new agreement commits $340 million in environmental investments tied to the Conowingo Dam’s long-term operation, setting an example of successful citizen advocacy.
Maryland this month finalized a $340 million deal with Constellation Energy to relicense the Conowingo Dam in Cecil County, ending years of litigation and regulatory uncertainty. The agreement restores the state’s authority to enforce water quality standards under the Clean Water Act and sets a possible precedent for dozens of hydroelectric relicensing cases nationwide expected in coming years.
