Local officials are often viewed as relatively weak actors in China’s governance structure, largely implementing policies issued from the central level.
However, a new book – “Implementing a low-carbon future: climate leadership in Chinese cities” – argues that these officials play an important role in designing innovative and enduring climate policy.
The book follows how four cities – Shenzhen, Zhenjiang, Xiamen and Nanchang – approached developing low-carbon policies over the course of almost a decade.
It identifies “bridge leaders” – mid-level local bureaucrats who have a strong interest in a specific policy area and who are unlikely to move often between different posts – as key to effective local climate policymaking.
Carbon Brief interviews author Weila Gong, non-resident scholar at the UC San Diego School of Global Policy and Strategy’s 21st Century China Center and visiting scholar at UC Davis, on her research.
The interview has been edited for length and clarity.
- Gong on why cities are important: “Over 85% of China’s carbon emissions come from cities. The majority of Chinese people live in cities, so the extent to which cities can become truly low-carbon will also influence China’s climate success.”
- On what motivates local policymakers: “Mid-level bureaucrats need to think about how to create unique, innovative and visible policy actions to help draw attention to their region and their bosses.”
- On cities as a way to test new policies: “Part of the function of local governments in China is to experiment with policy at a local level, thereby helping national-level officials develop responses to emerging policy challenges.”
- On how local policymakers get results: “Even though we tend to think that local officials are very constrained in terms of policy or financial resources, they can often have the leverage and space to build coalitions.”
- On uneven city-level engagement: “To begin with, all regions received political support if they joined the [low-carbon city] pilot programme. But over the years, different regions have engaged very differently.”
- On the need for ‘entrepreneurial bureaucrats’: “China will always need local officials willing to introduce new legislations or try new policy instruments…For that, it needs entrepreneurial bureaucrats who are willing to turn ideas into actions.”
- On international cooperation: “Even with how geopolitics is really complicating things, many cities continue to have common challenges. For example, collaboration between Shanghai and Los Angeles on green shipping corridors is still ongoing”.
- On the effectiveness of mid-level bureaucrats: “They are creative, they know how to convince their boss about the importance of climate action and they know how that can bring opportunities for themselves and their boss. And because of how long they have worked in one area, they understand the local politics, policy processes and the coalitions needed to provide solutions.”
Carbon Brief: You’ve just written a book about climate policy in Chinese cities. Could you explain why subnational governments are important for China’s climate policy in general?
Weila Gong: China is the world’s largest carbon emitter, so the extent to which global efforts to address climate change can actually reach their goal is largely influenced by China’s efforts.
If you look at the structure of China’s carbon emissions, over 85% of China’s carbon emissions come from cities. The majority of Chinese people live in cities, so the extent to which cities can become truly low-carbon will also influence China’s climate success. That’s why I started to look at this research area.
We tend to think of China as a centralised, big system and a unitary state – state-run and top-down – but it actually also has multi-level governance. No climate action or national climate targets can be achieved without local engagement.
We also tend to think subnational level [actors], including the provincial, city and township levels, are barriers for environmental protection, because they are focused on promoting economic growth.
But I observed these actors participating in China’s low-carbon city pilot programme [as part of my fieldwork spanning most of the 2010s]. I was really surprised to see so many cities wanted to participate in the pilot, even though at the time there was no specific evaluation system that would reward their efforts.
We think of local governments just as implementers of central-level policy. When it comes to issues like climate change and also low-carbon development – in 2010 [policymakers found these concepts] very vague…So I was curious why those local officials would want to take on this issue, given that there was no immediate reward, either in terms of career development or in terms of increasing financial support from the central government.
CB: Could you help us understand the mindset of these bureaucrats? How do local-level officials design policies in China?
WG: The role of different local officials in promoting low-carbon policy is not very well understood. We tend to focus on top political figures, such as mayors or [municipal] party secretaries, because we see them as the most important policymakers.
But that is not entirely true. Those top local politicians are very important in supporting efforts to tackle problem areas…but the focus in my book is the mid-level bureaucrats.
Unlike mayors and party secretaries, mid-level officials tend to stay in one locality for their entire career. That helps us to understand why climate policy can become durable in some places and not others.
Mayors and party secretaries are important for [pushing through policy solutions to problem] issues, but they can also be key barriers for ensuring continuation of those policies – particularly when they change positions…as they tend to move to another locality every three to five years.
Therefore, these top-level officials are not the ones implementing low-carbon policies. That’s why I looked at the mid-level bureaucrats instead.
The conventional understanding of these bureaucrats is that they are obedient and only follow their bosses’ guidance. But actually, when low-carbon policies emerged as an important area for the central government in 2010, opportunities appeared for local governments to develop pilot projects.
Mid-level local officials saw this as a way to help their bosses – the mayors and party secretaries – increase their chances of getting promoted, which in turn would help the mid-level bureaucrats to advance their own career.
Impressing central government officials isn’t really a consideration for these officials…but their bosses need visible or more reliable local actions to show their ability to enforce low-carbon development.
As such, mid-level bureaucrats need to think about how to create unique, innovative and visible policy actions to help draw attention to their region and their bosses.
Secondly, mid-level bureaucrats are more interested in climate issues if it is in the interest of their agency or local government.
For example, Zhenjiang [a city in east China] came to be known as a leader in promoting low-carbon development due to a series of early institutional efforts to establish low-carbon development. In particular, in part because of this, it was chosen for a visit by president Xi Jinping in 2014.
As a result, the city created a specialised agency [on low-carbon development]. This made it one of the first regions to have full-time local officials that followed through on low-carbon policy implementation.
This increased their ability to declare their regulatory authority on low-carbon issues, by being able to promote new regulations, standards and so on, as well as enhancing the region’s and the local policymakers’ reputations by building institutions to ensure long-term enforcement.
Another motivation for many local governments is accessing finance through the pilot programmes. If their ideas impress the central-level government, local policymakers could get access to investment or other forms of financial resources from higher levels of government.
In the city of Nanchang, for example, officials were trying to negotiate access to external investment, because the main central government fund for low-carbon initiatives only provided minimal finance.
Nanchang officials tried to partner with the Austrian government on sustainable agriculture, working through China’s National Development and Reform Commission (NDRC).
It didn’t materialise in the end, but they still created a platform to attract international investment, and gathered tens of millions of yuan [millions of dollars] in central-level support because the fact they showed they were innovating allowed them to access more money through China’s institutional channels.
CB: Could you give an example of what drives innovative local climate policies?
WG: National-level policies and pilot programme schemes provide openings for local governments to really think about how and whether they should engage more in addressing climate change.
The national government has participated in international negotiations on climate for decades…but subnational-level cities and provinces only joined national efforts to address climate issues from the 2010s – starting with the low-carbon city programme.
So we can see that local responses to addressing climate change have been shaped by the opportunities provided by the national government, [who in turn] want more local-level participation to give them successful case studies to take to international conferences.
Local carbon emission trading systems (ETSs) are an example of giving local governments opportunities to experiment.
In my book, I look at the case of Shenzhen, which launched China’s first local ETS. [Shenzhen was one of seven regions selected to run a pilot ETS, ahead of the national ETS being established in 2018.]
Part of the function of local governments in China is to experiment with policy at a local level, thereby helping national-level officials develop responses to emerging policy challenges.
I remember a moment during my field research in 2012, when I was with a group of officials from both the national and local government.
The national government officials asked the local officials to come up with some best practices and solutions, to help them envision what could be done at the national level.
Then there are drivers at the international level, which I think is very interesting.
I observed that the officials particularly willing to take on climate issues usually had access to international training.
During the early stages of subnational climate engagement, organisations such as the German Agency for International Cooperation (GIZ) worked with the NDRC and other national-level agencies to train local officials across the country.
This created more opportunities to help local officials understand what climate change and carbon markets were, and how to use policy instruments to support low-carbon development.
In Shenzhen, local bureaucrats also turned to their international partners to help them design policy.
The city created a study group to visit partners working on the EU ETS and learn how it was designed. They learned about price volatility in the EU ETS and pushed legislation through the local people’s congress [to mitigate this in their own system].
One thing that made the Shenzhen ETS so successful is what I call “entrepreneurial bureaucrats” [who have the ability to design, push through and maintain new local-level climate policies].
Shenzhen’s vice mayor worked with the local people’s congress to push the ETS legislation through. This was the first piece of legislation in China to require compulsory participation by more than 600 local industrial actors. It also granted the local government authority to decide the quotas and scope of the ETS.
These 600 entities also included Shenzhen’s public building sector[, a powerful local interest group].
This shows that, even though we tend to think that local officials are very constrained in terms of policy or financial resources, they can often have the leverage and space to build coalitions – even in China’s more centralised political system – and know how to mobilise political support.
CB: You chose to look at the effectiveness of four cities – Shenzhen, Zhenjiang, Xiamen and Nanchang – in climate policymaking. Why did you choose these cities and how representative are they of the rest of China?
WG: We tend to believe that only economically-advanced areas or environmentally-friendly cities will become champions for low-carbon development…But I was surprised, because Zhenjiang and Nanchang are not known for having an advanced economy, but [they nevertheless built impactful climate] institutions – regulations, standards and legislation that shape individual and organisational behaviours in the long term. I thought they were interesting examples of how local regions can really create those institutions.
Then there was Xiamen, which is seen as an environmentally-friendly city and economically is comparable to Shenzhen when you look at GDP per capita. Xiamen actually did not turn its low-carbon policy experimentation into long-term institutions, instead randomly proposing new initiatives [that were not sustained].
I conducted more than 100 interviews, talking with policy-practitioners inside and outside of government about specific policies, their processes and implementation.
I found that, over the course of eight years, these [cities] showed very different levels of engagement.
Some I categorised into substantive engagement, where the local government delivered on their climate goals. [Shenzhen falls into this category.]
Then there is performative engagement – such as in the case of Nanchang – where the local government was more interested in [using climate policies to] attract external investment and access projects from higher levels of government.
But they were not able to enforce the policies, because impressing higher levels of government became the primary motivation.
Zhenjiang was a case of symbolic engagement. It actually created a lot of institutions, such as a specialised agency and a screening system to ensure new [low-carbon] investment. When I was observing Zhenjiang, from 2012 to 2018, officials recognised they needed to be carbon-constrained.
The problem was that Zhenjiang has a very strong power sector – mainly coal power – which supplies the whole eastern coast. That meant, even though the government was very determined to promote low-carbon policies, they faced [opposition from] very strong local actors – meaning the government could only partially implement the targets they set.
Then there is sporadic engagement, as seen in Xiamen. [The city’s approach to climate policy was incremental and cautious] because of a lack of political support [from officials in Xiamen], as well as local coalitions between key actors. So instead, we find random initiatives being promoted.
This explains the uneven policy implementation in China. To begin with, all regions received political support if they joined the pilot programme. But over the years, different regions have engaged very differently, in terms of the regulations, standards and legislation they have introduced, and whether those were paired with enforcement by a group of trained personnel to follow through on those initiatives.
CB: What needs to be done to strengthen sub-national climate policy making?
WG: It’s very important to have groups of personnel trained on climate policy. Since 2010, when I started studying the low-carbon pilot programme, there were no provincial-level people or agencies fully responsible for climate change. Back then, there was only the [central-level] department of climate change under the NDRC.
By the time I finished the book, provincial-level departments of climate change had been created across all provinces. But almost nothing has been established at the city level, so most city-level climate initiatives are being managed under the agencies responsible for air quality.
That means climate change is only one of those local officials’ day-to-day responsibilities. Only a handful of cities have dedicated staff working on climate issues: Beijing, Shanghai, Zhenjiang, Shenzhen and Guiyang.
Nanchang devised some of China’s first legislation to include an annual [financial] budget for low-carbon development. But when I revisited the city, officials were not actually sure about how and whether that budget was being used, because there wasn’t a person responsible for it.
Therefore, even if there are resources available, they can go unused because local officials at the city level are so busy. If climate policy is not prioritised, or written into their job responsibilities, that can be a challenge for sustaining implementation.
In China’s governance structure, the national government comes up with ideas, and the provincial level transfers these ideas down to local-level governments. City-level governments are the ones implementing these ideas.
So we need full-time staff to follow through on policies from the beginning right up to implementation.
Secondly, while almost all cities have now made carbon-peaking plans, one area in which the Chinese government can make further progress is in data.
China has recently emphasised the need to strengthen carbon-emissions data collection and monitoring. But when I was conducting my research, most Chinese cities had not yet established regular carbon-accounting systems.
As such, inadequate energy statistics and insufficient detail remain key barriers to effective climate-policy implementation.
In addition, the relevant data usually is owned by China’s National Bureau of Statistics (NBS), which does not always share it with other agencies. Local agencies can’t always access detailed data.
When I visited Xiamen, officials told me the local government is now improving emissions monitoring systems. But there should be more systematic and rigorous data collection, covering both carbon emissions and non-CO2 greenhouse gases. Also, much of the company-level data is self-reported, which could affect the accuracy of carbon-emissions statistics.
For continued climate action, it’s also important that the central government ensures that local officials have the institutional support needed to experiment and propose new ideas.
…China will always need local officials willing to introduce new legislations or try new policy instruments – like Shenzhen with its ETS, or establishing new carbon-monitoring platforms.
For that, it needs entrepreneurial bureaucrats who are willing to turn ideas into actions. Ensuring that local governments have the right set of conditions to do this is very important.
CB: What did you find most surprising when researching this book?
WG: That international collaboration is still very important. I found that many officials learnt about climate change through international engagement.
In the current situation, I think international engagement is still very important – particularly given how, even with how geopolitics is really complicating things, many cities continue to have common challenges. For example, collaboration between Shanghai and Los Angeles on green shipping corridors is still ongoing.
That can bring opportunities for continuing climate action at the city level in the face of rising international tensions, as long as national governments give them space to be involved in international climate action.
Another surprise was the factors of what exactly made climate action durable. I was really surprised that many of the cities that I revisited were still involved in the pilot programmes, despite the central government restructuring that shifted the climate change portfolio from the NDRC to the Ministry of Ecology and Environment – which created challenges for the local governments who had to navigate this.
I also thought that the change in mayors for all four cities would lead to climate initiatives falling off the agenda.
But actually, Zhenjiang, Xiamen and Nanchang all maintained their low-carbon initiatives, despite these changes. This showed it isn’t only strong mayors that bring success, but rather a group of trained personnel building and enforcing regulations and standards. So the importance of bureaucrats and bureaucracy in making climate action durable was actually way beyond my initial expectations.
I was also surprised that bureaucrats can be entrepreneurial, even though they work in a centralised system. They are creative, they know how to convince their boss about the importance of climate action and they know how that can bring opportunities for themselves and their boss. And because of how long they have worked in one area, they understand the local politics, policy processes and the coalitions needed to provide solutions.

Analysis: UK newspaper editorial opposition to climate action overtakes support for first time
Nearly 100 UK newspaper editorials opposed climate action in 2025, a record figure that reveals the scale of the backlash against net-zero in the right-leaning press.
Carbon Brief has analysed editorials – articles considered the newspaper’s formal “voice” – since 2011 and this is the first year opposition to climate action has exceeded support.
Criticism of net-zero policies, including renewable-energy expansion, came entirely from right-leaning newspapers, particularly the Sun, the Daily Mail and the Daily Telegraph.
In addition, there were 112 editorials – more than two a week – that included attacks on Ed Miliband, continuing a highly personal campaign by some newspapers against the Labour energy secretary.
These editorials, nearly all of which were in right-leaning titles, typically characterised him as a “zealot”, driving through a “costly” net-zero “agenda”.
Taken together, the newspaper editorials mirror a significant shift on the UK political right in 2025, as the opposition Conservative party mimicked the hard-right populist Reform UK party by definitively rejecting the net-zero target that it had legislated for and the policies that it had previously championed.
Record climate opposition
Nearly 100 UK newspaper editorials voiced opposition to climate action in 2025 – more than double the number of editorials that backed climate action.
As the chart below shows, 2025 marked the fourth record-breaking year in a row for criticism of climate action in newspaper editorials.
This also marks the first time that editorials opposing climate action have overtaken those supporting it, during the 15 years that Carbon Brief has analysed.

This trend demonstrates the rapid shift away from a long-standing political consensus on climate change by those on the UK’s political right.
Over the past year, the Conservative party has rejected both the “net-zero by 2050” target that it legislated for in 2019 and the underpinning Climate Change Act that it had a major role in creating. Meanwhile, the Reform UK party has been rising in the polls, while pledging to “ditch net-zero”.
These views are reinforced and reflected in the pages of the UK’s right-leaning newspapers, which tend to support these parties and influence their politics.
All of the 98 editorials opposing climate action were in right-leaning titles, including the Sun, the Daily Mail, the Daily Telegraph, the Times and the Daily Express.
Conversely, nearly all of the 46 editorials pushing for more climate action were in the left-leaning and centrist publications the Guardian and the Financial Times. These newspapers have far lower circulations than some of the right-leaning titles.
In total, 81% of the climate-related editorials published by right-leaning newspapers in 2025 rejected climate action. As the chart below shows, this is a marked difference from just a few years ago, when the same newspapers showed a surge in enthusiasm for climate action.
That trend had coincided with Conservative governments led by Theresa May and Boris Johnson, which introduced the net-zero goal and were broadly supportive of climate policies.

Notably, none of the editorials opposing climate action in 2025 took a climate-sceptic position by questioning the existence of climate change or the science behind it. Instead, they voiced “response scepticism”, meaning they criticised policies that seek to address climate change.
(The current Conservative leader, Kemi Badenoch, has described herself as “a net-zero sceptic, not a climate change sceptic”. This is illogical as reaching net-zero is, according to scientists, the only way to stop climate change from getting worse.)
In particular, newspapers took aim at “net-zero” as a catch-all term for policies that they deemed harmful. Most editorials that rejected climate action did not even mention the word “climate”, often using “net-zero” instead.
This supports recent analysis by Dr James Painter, a research associate at the University of Oxford, which concluded that UK newspaper coverage has been “decoupling net-zero from climate change”.
This is significant, given strong and broad UK public support for many of the individual climate policies that underpin net-zero. Notably, there is also majority support for the “net-zero by 2050” target itself.
Much of the negative framing by politicians and media outlets paints “net-zero” as something that is too expensive for people in the UK.
In total, 87% of the editorials that opposed climate action cited economic factors as a reason, making this by far the most common justification. Net-zero goals were described as “ruinous” and “costly”, as well as being blamed – falsely – for “driving up energy costs”.
The Sunday Telegraph summarised the view of many politicians and commentators on the right by stating simply that said “net-zero should be scrapped”.
While some criticism of net-zero policies is made in good faith, the notion that climate change can be stopped without reducing emissions to net-zero is incorrect. Alternative policies for tackling climate change are rarely presented by critical editorials.
Moreover, numerous assessments have concluded that the transition to net-zero can be both “affordable” and far cheaper than previously thought.
This transition can also provide significant economic benefits, even before considering the evidence that the cost of unmitigated warming will significantly outweigh the cost of action.
Miliband attacks intensify
Meanwhile, UK newspapers published 112 editorials over the course of 2025 taking personal aim at energy security and net-zero secretary Ed Miliband.
Nearly all of these articles were in right-leaning newspapers, with the Sun alone publishing 51. The Daily Mail, the Daily Telegraph and the Times published most of the remainder.
This trend of relentlessly criticising Miliband personally began last year in the run up to Labour’s election victory. However, it ramped up significantly in 2025, as the chart below shows.

Around 58% of the editorials that opposed climate action used criticism of climate advocates as a justification – and nearly all of these articles mentioned Miliband, specifically.
Editorials denounced Miliband as a “loon” and a “zealot”, suffering from “eco insanity” and “quasi-religious delusions”. Nicknames given to him include “His Greenness”, the “high priest of net-zero” and “air miles Miliband”.
Many of these attacks were highly personal. The Daily Mail, for example, called Miliband “pompous and patronising”, with an “air of moral and intellectual superiority”.
Frequently, newspapers refer to “Ed Miliband’s net-zero agenda”, “Ed Miliband’s swivel-eyed targets” and “Mr Miliband’s green taxes”.
These formulations frame climate policies as harmful measures that are being imposed on people by the energy secretary.
In fact, the Labour government decisively won an election in 2024 with a manifesto that prioritised net-zero policies. Often, the “targets” and “taxes” in question are long-standing policies that were introduced by the previous Conservative government, with cross-party support.
Moreover, the government’s climate policy not only continues to rely on many of the same tools created by previous administrations, it is also very much in line with expert evidence and advice. This is to prioritise the expansion of clean power and to fuel an economy that relies on increasing levels of electrification, including through electric cars and heat pumps.
Despite newspaper editorials regularly calling for Miliband to be “sacked”, prime minister Keir Starmer has voiced his support both for the energy secretary and the government’s prioritisation of net-zero.
In an interview with podcast The Rest is Politics last year, Miliband was asked about the previous Carbon Brief analysis that showed the criticism aimed at him by right-leaning newspapers.
Podcast host Alastair Campbell asked if Miliband thought the attacks were the legacy of his strong stance, while Labour leader, during the Leveson inquiry into the practices of the UK press. Miliband replied:
“Some of these institutions don’t like net-zero and some of them don’t like me – and maybe quite a lot of them don’t like either.”
Renewable backlash
As well as editorial attitudes to climate action in general, Carbon Brief analysed newspapers’ views on three energy technologies – renewables, nuclear power and fracking.
There were 42 newspaper editorials criticising renewable energy in 2025. This meant that, for the first time since 2014, there were more anti-renewables editorials than pro-renewables editorials, as the chart below shows.
As with climate action more broadly, this was a highly partisan issue. The Times was the only right-leaning newspaper that published any editorials supporting renewables.

By far the most common stated reason for opposing renewable energy was that it is “expensive”, with 86% of critical editorials using economic arguments as a justification.
The Sun referred to “chucking billions at unreliable renewables” while the Daily Telegraph warned of an “expensive and intermittent renewables grid”.
At the same time, editorials in supportive publications also used economic arguments in favour of renewables. The Guardian, for example, stressed the importance of building an “affordable clean-energy system” that is “built on renewables”.
There was continued support in right-leaning publications for nuclear power, despite the high costs associated with the technology. In total, there were 20 editorials supporting nuclear power in 2025 – nearly all in right-leaning newspapers – and none that opposed it.
Fracking was barely mentioned by newspapers in 2023 and 2024, after a failed push by the Conservatives under prime minister Liz Truss to overturn a ban on the practice in 2022. This attempt had been accompanied by a surge in supportive right-leaning newspaper editorials.
There was a small uptick of 15 editorials supporting fracking in 2025, as right-leaning newspapers once again argued that it would be economically beneficial.
The Sun urged current Conservative leader Badenoch to make room for this “cheap, safe solution” in her future energy policy. The government plans to ban fracking “permanently”.
North Sea oil and gas remained the main fossil-fuel policy focus, with 30 editorials – all in right-leaning newspapers – that mentioned the topic. Most of the editorials arguing for more extraction from the North Sea also argued for less climate action or opposed renewable energy.
None of these editorials noted that the UK is expected to be significantly less reliant on fossil-fuel imports if it pursues net-zero, than if it rolls back on climate action and attempts to squeeze more out of the remaining deposits in the North Sea.
Methodology
This is a 2025 update of previous analysis conducted for the period 2011-2021 by Carbon Brief in association with Dr Sylvia Hayes, a research fellow at the University of Exeter. Previous updates were published in 2022, 2023 and 2024.
The count of editorials criticising Ed Miliband was not conducted in the original analysis.
The full methodology can be found in the original article, including the coding schema used to assess the language and themes used in editorials concerning climate change and energy technologies.
The analysis is based on Carbon Brief’s editorial database, which is regularly updated with leading articles from the UK’s major newspapers.

DeBriefed 16 January 2026: Three years of record heat; China and India coal milestone; Beijing’s 2026 climate outlook
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Hottest hat-trick
STATE OF THE CLIMATE: Scientists have announced that 2025 was either the second or third hottest year on record, with close margins between last year and 2023, reported the Associated Press. The newswire noted that “temperature averages for 2025 hovered around – and mostly above – 1.4C of industrial era warming”. Bloomberg said that this happened despite the natural weather phenomenon La Niña, which “suppresses global temperatures”, meaning “heat from greenhouse gases countered that cooling influence”. Carbon Brief’s comprehensive analysis of the data found cumulative global ice loss also “reached a new record high in 2025”.
OVERHEATING OCEANS: Separately, the world’s oceans “absorbed colossal amounts of heat in 2025”, said the Guardian, setting “yet another new record and fuelling more extreme weather”. It added that the “extra heat makes the hurricanes and typhoons…more intense, causes heavier downpours of rain and greater flooding and results in longer marine heatwaves”.
FIRE AND ICE: Wildfires in Australia have destroyed around 500 structures, said the Sydney Morning Herald, with a “dozen major fires” still burning. A wildfire in Argentinian Patagonia has “blazed through nearly 12,000 hectares” of scrubland and forests, according to the Associated Press. Meanwhile, parts of the Himalayas are “snowless” for the first time in nearly four decades, signalling a “climatic anomaly”, reported the Times of India.
Around the world
- EMISSIONS REBOUND: US emissions rose 2% last year after two years of declines” due to a rise in coal power generation, said Axios, in coverage of research by the Rhodium Group.
- ‘UNINVESTABLE’ OIL: US president Donald Trump may “sideline” ExxonMobil from Venezuela’s oil market after its comment that Venezuela is “uninvestable”, reported CNBC. TotalEnergies is also “in no rush to return to Venezuela”, said Reuters.
- PRICE WARS: The EU issued guidelines that will allow tariffs on Chinese electric vehicles to be removed in exchange for minimum price commitments, said Reuters.
- ‘RECORD’ AUCTION: The UK government has secured “8.4 gigawatts of new offshore wind power” in a “record” auction, said Sky News. Although the auction saw some price rises, this will likely be “cost neutral” for consumers, Carbon Brief said – contrary to the “simplistic and misleading” narratives promoted by some media outlets.
- COP STRATEGY: The Guardian reported that Chris Bowen, the Australian minister appointed “president of negotiations” for COP31, plans to use his role to lobby “Saudi Arabia and others” on the need to phase out fossil fuels.

Captured

Both China and India saw coal power generation fall in 2025, in the “first simultaneous drop in half a century”, found new analysis for Carbon Brief, which was widely reported around the world. It noted that, for both countries, the decline in coal was driven by new clean-energy capacity additions, which were “more than sufficient to meet rising demand”.

What are China experts watching for in 2026?
The year 2026 will be pivotal for China’s climate policy. In March, the government will release key climate and energy targets for 2030, the year by which China has pledged to have peaked its emissions.
At the same time, with the US increasingly turning away from climate policy and towards fossil fuel expansionism, China’s role in global climate action is more important than ever.
Carbon Brief asks leading experts what they are watching for from China over the year ahead.
Shuo Li, director of the China Climate Hub, Asia Society Policy Institute
After decades of rapid growth, independent analyses suggest China’s CO2 emissions may have plateaued or even begun to decline in 2025.
The transition from emissions growth to stabilisation and early decline will be the key watch point for 2026 and will be shaped by the forthcoming 15th five-year plan. [This plan will set key economic goals, including energy and climate targets, for 2030.]
However, the precise timing, scale and enforceability of these absolute emissions control measures remain under active debate. Chinese experts broadly agree that if the 2021-2025 period was characterised by continued emissions growth, and 2031-2035 is expected to deliver a clear decline, then 2026-2030 will serve as a critical “bridge” between the two.

First, the 15th five-year plan inaugurates the “dual control of carbon” system. This year marks the first time industries and local governments face binding caps on total emissions, not just intensity.
Second, the national carbon market is aggressively tightening. With the inclusion of steel, cement and aluminum this year, regulators are executing a “market reset” – de-weighting older allowances [meaning they cannot be used to contribute to polluters’ obligations for 2026] and enforcing stricter benchmarks to bolster prices ahead of the full rollout of the EU’s carbon border adjustment mechanism.

China’s solar manufacturing overcapacity is prompting Beijing’s first serious consolidation efforts. At the same time, its offshore wind technology is advancing rapidly [and there are] signals that Chinese wind companies are pursuing entry into European markets through local production, mirroring strategies adopted by battery manufacturers.
Together, these dynamics suggest that the next phase of cleantech competition will be shaped less by trade defense alone and more by the interaction between Chinese supply-side reforms and global market-absorption capacity.

China’s electric vehicle (EV) industry has been the primary force pushing the global passenger vehicle market toward clean energy. That momentum should continue. But a growing headwind has emerged: tariffs. Mexico, Brazil, Europe and the US are just a few of the countries raising barriers, complicating the next phase of global EV expansion.
One new wildcard: the US now effectively controls Venezuelan oil. If that meaningfully impacts global oil prices, it could either slow – or unexpectedly accelerate – the shift toward clean-energy vehicles.

Brazil’s biodiversity pledge: Six key takeaways for nature and climate change
The world’s most biodiverse nation, Brazil, has belatedly published its UN plan for halting and reversing nature decline by the end of this decade.
Brazil is home to 10-15% of all known species on Earth, 64% of the Amazon rainforest and it supplies 10% of global food demand, according to official estimates.
It was among around 85% of nations to miss the 2024 deadline for submitting a new UN nature plan, known as a national biodiversity strategy and action plan (NBSAP), according to a joint investigation by Carbon Brief and the Guardian.
On 29 December 2025, Brazil finally published its new NBSAP, following a lengthy consultation process involving hundreds of scientists, Indigenous peoples and civil society members.
The NBSAP details how the country will meet the goals and targets of the Kunming-Montreal Global Biodiversity Framework (GBF), the landmark deal often described as the “Paris Agreement” for nature, agreed in 2022.
Below, Carbon Brief walks through six key takeaways from Brazil’s belated NBSAP:
- The government plans to ‘conserve’ 80% of the Brazilian Amazon by 2030
- It plans to ‘eliminate’ deforestation in Brazilian ecosystems by 2030
- Brazil has ‘aligned’ its actions on tackling climate change and biodiversity loss
- The country seeks to ‘substantially increase’ nature finance from a range of sources
- Brazil’s plans for agriculture include ‘sustainable intensification’
- Brazil conducted a largest-of-its-kind consultation process before releasing its NBSAP
The government plans to ‘conserve’ 80% of the Brazilian Amazon by 2030
The third target of the GBF sets out the aim that “by 2030 at least 30% of terrestrial, inland water and of coastal and marine areas…are effectively conserved and managed”. This is often referred to as “30 by 30”.
Previous analysis by Carbon Brief and the Guardian found that more than half of countries’ pledges were not aligned with this aim. (Importantly, all of the GBF’s targets are global ones and do not prescribe the amount of land that each country must protect.)
Brazil’s NBSAP sets a substantially higher goal – it seeks to conserve 80% of the Amazon rainforest within its borders, as well as 30% of the country’s other ecosystems.
Since Brazil is one of the largest countries in the world, in addition to being the most biodiverse, this higher target represents a significant step towards achieving the global target.
For the purposes of its protected areas target, Brazil considers not just nationally designated protected areas, but also the lands of Indigenous peoples, Quilombola territories and other local communities.
As the NBSAP notes, Brazil has already taken several steps towards achieving the “30 by 30” target.
In 2018, the country created or expanded four marine protected areas in its territorial waters, increasing its protected area coverage from around 1.5% to greater than 25%.
According to Brazil’s sixth national report, submitted to the CBD in 2020, 18% of the country’s “continental area” – that is, its land and inland waters – was part of a protected area. More than 28% of the Amazon received such a designation.
A further 12% of the country is demarcated as Indigenous lands, which “provide important protection to a large territorial extension of the country, particularly in the Amazon biome”, the report says.
The action plan that accompanies the new NBSAP sets out 15 actions in support of achieving target three, including recognising and titling Indigenous lands, establishing ecological corridors and biosphere reserves and implementing national strategies for mangrove, coral reef and wetlands protection.
It plans to ‘eliminate’ deforestation in Brazilian ecosystems by 2030
As well as committing to the GBF targets of protecting and restoring ecosystems, Brazil’s NBSAP also sets a separate target to “eliminate” deforestation in Brazilian biomes by 2030.
Target 1B of Brazil’s NBSAP says that the country aims to “achieve zero deforestation and conversion of native vegetation by 2030”.
The country hopes to achieve this “through the elimination of illegal deforestation and conversion, compensation for the legal suppression of native vegetation, prevention and control of wildfires, combating desertification and attaining land degradation neutrality”.
This goes above and beyond what is set out in the GBF, which does not mention “deforestation” at all.
Brazilian president Luiz Inácio Lula da Silva was reelected as leader in 2022 on a promise to achieve “zero deforestation”, following a rise in Amazon destruction under his predecessor, Jair Bolsonaro.
Data from Global Forest Watch (GFW), an independent satellite research platform, found that deforestation in the Brazilian Amazon fell by a “dramatic” 36% in 2023 under Lula.
However, Brazil remains the world’s largest deforester. Separate GFW data shows that the country accounted for 42% of all primary forest loss in 2024 – with two-thirds of this driven by wildfires fuelled by a record drought.
Brazil has ‘aligned’ its actions on tackling climate change and biodiversity loss
Brazil’s NBSAP comes shortly after it hosted the COP30 climate summit in the Amazon city of Belém in November.
One of the presidency’s priorities at the talks was to bring about greater coordination between global efforts to tackle climate change and biodiversity loss.
At the Rio Earth summit in 1992, the world decided to address Earth’s most pressing environmental problems under three separate conventions: one on climate change, one on biodiversity and the final one on land desertification.
But, for the past few years, a growing number of scientists, politicians and diplomats have questioned whether tackling these issues separately is the right approach.
And, at the most recent biodiversity and land desertification COPs, countries agreed to new texts calling for closer cooperation between the three Rio conventions.
At COP30, the Brazilian presidency attempted to negotiate a new text to enhance “synergies” between the conventions. However, several nations, including Saudi Arabia, vocally opposed the progression of a substantive outcome.
Following on from this, Brazil’s NBSAP states that its vision for tackling nature loss is “aligned” with its UN climate plan, known as a nationally determined contribution (NDC).
In addition, the NBSAP states that Brazil is taking a “holistic approach to addressing the existing crises of climate change and biodiversity loss in a synergistic manner”.
It lists several targets that could help to address both environmental problems, including ending deforestation, promoting sustainable agriculture and restoring ecosystems.
Brazil joins a small number of countries, including Panama and the UK, that have taken steps to bring their actions to tackle climate change and biodiversity loss into alignment.
The country seeks to ‘substantially increase’ nature finance from a range of sources
According to target 19 of the NBSAP, the Brazilian government will “develop and initiate” a national strategy to finance the actions laid out in the document by the end of 2026.
This financial plan “should aim to substantially increase…the volume of financial resources” for implementing the NBSAP.
These resources should come in the form of federal, state and municipal funding, international finance, private funding and incentives for preserving biodiversity, the document continues.
The accompanying action plan includes a number of specific mechanisms, which could be used to finance efforts to tackle nature loss. These include biodiversity credits, a regulated carbon market and the Tropical Forest Forever Facility.
Separately, the NBSAP sets out a goal in target 18 of identifying “subsidies and economic and fiscal incentives that are directly harmful to biodiversity” by the end of this year. Those identified subsidies should then be reduced or eliminated by 2030, it adds.
The document notes that the phaseout of harmful subsidies should be accompanied by an increase in incentives for “conservation, restoration and sustainable use of biodiversity”.
The NBSAP does “important work” in translating the targets of the GBF into “ambitious targets” in the national context, says Oscar Soria, co-founder and chief executive of civil-society organisation the Common Initiative.
Soria tells Carbon Brief:
“While the document is laudable on many aspects and its implementation would change things for the better, the concrete financial means to make it a reality – funding it and halting the funding of activities going against it – are still lacking. In this regard, this NBSAP is a good example of the GBF’s problem at the global level.
“The hardest part of political negotiations will begin only now: in 2026, the Brazilian government will have to evaluate the cost of implementing the NBSAP and where finance will come from.”
Brazil’s plans for agriculture include ‘sustainable intensification’
Brazil is one of the world’s leading food producers, meeting 10% of global demand, according to its NBSAP.
It is also the world’s largest grower of soya beans and the second-largest cattle producer.
However, agriculture is also a major driver of biodiversity loss in Brazil, largely due to the clearing of rainforest or other lands for soya growing and cattle ranching. Agriculture itself is also affected by biodiversity loss, particularly the loss of pollinators. The NBSAP says:
“Biodiversity loss directly undermines agricultural production and human well-being, demonstrating that agriculture, other productive activities and biodiversity conservation are interdependent rather than antagonistic.”
Brazil’s NBSAP addresses sustainable agriculture in target 10A, which aims to “ensure that, by 2030, areas under agriculture, livestock, aquaculture and forestry are managed sustainably and integrated into the landscape”.
It lists several approaches to achieving sustainable production, including agroecology, regenerative agriculture and sustainable intensification.
Targets seven and 10B also pertain to food systems. Target seven seeks to reduce the impacts of pollution, including nutrient loss and pesticides, on biodiversity, while target 10B commits to the sustainable fishing and harvesting of other aquatic resources.
In 2021, Brazil launched its national low-carbon agriculture strategy, known as the ABC+ plan. The plan promotes sustainability in the agricultural sector through both adaptation and mitigation actions.
Brazil conducted a largest-of-its-kind consultation process before releasing its NBSAP
Brazil was among the majority of nations to miss the UN deadline to submit a new NBSAP before the COP16 biodiversity summit in Colombia in October 2024.
At the time, a representative from the Brazilian government said that it was unable to meet the deadline because it was embarking on an ambitious consultation process for its NBSAP.
Braulio Dias, director of biodiversity conservation at the Brazilian Ministry of Environment, who is responsible for the NBSAP process, told Carbon Brief and the Guardian in 2024:
“Brazil is a huge country with the largest share of biodiversity [and] a large population with a complex governance. We are a federation with 26 states and 5,570 municipalities. We started the process to update our NBSAP in May last year and have managed to conclude a broad consultation process involving over a thousand people in face-to-face meetings.
“We are in the process of consolidating all proposals received, consulting all the departments of the Brazilian Ministry of the Environment and Climate Change, all the federal ministries and agencies engaged in the biodiversity agenda and the National Biodiversity Committee, before we can have a high-level political endorsement.
“Then we still have to build a monitoring strategy, a finance strategy and a communication strategy. We will only conclude this process toward the end of the year or early next year.”
In its NBSAP, the Brazilian government says it engaged with around 200 scientific and civil society organisations and 110 Indigenous representatives while preparing its NBSAP.
Around one-third of the Amazon is protected by Indigenous territories.
Indigenous peoples in Brazil have continuously called for more inclusion in UN processes to tackle climate change and nature loss, including by holding multiple demonstrations during the COP30 climate summit in November.
Michel Santos, public policy manager at WWF Brazil, says that many in Brazil’s civil society were pleased with the NBSAP’s extensive consultation process, telling Carbon Brief:
“Brazilian civil society is very happy with everything. It was a long process with broad participation. It took a while to be completed, but we consider the result quite satisfactory.”
