An essential guide to the week’s key developments relating to climate change.

This week

Hurricane Melissa

‘TOTAL DEVASTATION’: Hurricane Melissa has killed at least 49 people after sweeping through the Caribbean islands of Jamaica, Cuba, Haiti and Bermuda, reported Independent. Jamaica’s prime minister Andrew Holness said the storm left “total devastation”, destroying homes and infrastructure and leaving people “stranded on roofs and without power”, said BBC News. In Haiti, at least 30 people were killed in floods, Reuters added.

WARM WATERS: Melissa is tied as the strongest Atlantic hurricane to ever hit land, slamming Jamaica with winds of 185mph and fuelled by anomalously warm waters, reported the Associated Press. Fossil-fuelled climate change made the storm “four times more likely”, according to analysis cited by Agence France-Presse. Early estimates suggest infrastructure damage alone could amount to 40% of Jamaica’s gross domestic product, said the newswire.

RECORD RAINS: Elsewhere, Al Jazeera reported on major floods in central Vietnam, where the former imperial city of Huế saw record rainfall of more than 1,000mm over a 24-hour period, according to the country’s weather agency. The Associated Press reported that climate change is “driving more intense winds, heavier rainfall and shifting precipitation patterns across East Asia”.

Climate plans off track for 1.5C

‘DRASTICALLY SHORT’: The latest national climate plans will cause global emissions to drop 10% by 2035 from 2019 levels, “bending the emissions curve downwards for the first time”, but falling “drastically short” of the 60% cut needed to keep 1.5C in sight, said the Guardian. The plans – known as nationally determined contributions (NDCs) under the Paris Agreement – were assessed by the UN in a synthesis report ahead of COP30, the publication said. The 10% cut reflects plans announced by China and the EU, in addition to formal submissions from 64 countries, according to Reuters.

OVERSHOOT ‘INEVITABLE’: UN secretary-general António Guterres said in a joint interview with the Guardian and the Amazonian publication Sumaúma that overshooting 1.5C of global warming was now “inevitable” and would have “devastating consequences”. Guterres “did not give up on the [1.5C] target”, but urged world leaders to “change course” during COP30 to ensure the “overshoot is as short as possible and as low in intensity as possible to avoid tipping points like the Amazon”.

Captured

Carbon Brief explored the importance of soil health for food security and climate change in a new Q&A. As the diagram above illustrates, agricultural soil is composed of four layers – known as soil horizons – containing varying quantities of minerals, organic matter, living organisms, air and water. The world’s soils have lost 133bn tonnes of carbon since the advent of agriculture around 12,000 years ago, with crop production and cattle grazing responsible in equal part.

Crackdowns on climate and environmental activism

This week, Carbon Brief speaks to Mary Lawlor, UN special rapporteur on human rights defenders, who led a recent report highlighting crackdowns on the rights of climate and environmental activists around the world.

Carbon Brief: Why do you see climate change as a human-rights issue?

Mary Lawlor: I don’t think there’s any doubt about climate change being a human-rights issue nowadays, because everyone can see it. It interferes with so many rights. The right to food, for example. We’ve seen the situation where drought, storms and floods interfere with food production. And then if you look at the right to life – according to the WHO, we’re currently seeing an average of 175,000 heat-related deaths per year around the world, and those numbers will increase. But we now also have advisory opinions of the ICJ, the Inter-American Court of Human Rights, the International Tribunal for the Law of the Sea, all of which state clearly that climate change is a reality. They see it as a human-rights crisis.

CB: What human-rights violations are being faced by climate and environmental activists around the world right now?

ML: We went to a lot of Indigenous communities in the Amazon and we saw firsthand the threats against Indigenous defenders in Brazil who are opposing carbon-credit projects in their territories, where they themselves have been reducing deforestation with success for years. Then, for example, there were smears against a lawyer in Argentina who was supporting communities in their legal fight against the extraction of lithium from their territories without their consent. And, then, you have surveillance of climate activists organising peaceful protests against new fossil-fuel projects, for example, in the Philippines. So it’s kind of like an octopus, the tentacles are reaching out.

In some of the more developed countries, like France and Spain, you have accusations of terrorism against peaceful climate-justice movements. In Germany, you had the investigation and prosecution of a climate-justice group for alleged organised crime based solely on their peaceful protests that put no human being in danger and did no harm to anyone.

CB: What are some examples that you’ve seen of good practice by governments in relation to the work of climate and environmental activists?

ML: My favourite is Brazil and MST [Landless Workers’ Movement]. They were aided in their tree-planting programme by the federal authorities, who provided helicopters and the federal highway police piloted these helicopters. Seeds of the endangered juçara palm and araucaria trees could be air-dropped over land in Paraná, after the devastating fires that took place. So that’s my absolute favourite, because it showed how a state and defenders can work together as allies to prevent destruction and even worse climate change.

CB: According to Global Witness, 413 land and environmental defenders were killed in Brazil during 2012-2024. What is the current situation for environmental defenders in Brazil going into COP30?

[Brazil] are really making efforts, as far as I can see, to address the root causes – and this is really why human-rights defenders are in such danger – that is, land is at the heart of all the problems there. But progress is still very slow. At the moment, only 16 territories have been demarcated by [Brazilian president] Lula and that is hugely important because, as I said, it’s at the root of pretty much all the attacks and killings by either the thugs associated with the companies, or the big landowners, the illegal logging, and all the stuff that is happening there. So that is something that we really need a speed up of – the demarcation of Indigenous lands.

When it comes to COP30, they’ve put some effort into making it more inclusive, especially when it comes to bringing the voices and experiences of Indigenous defenders into the negotiations. Now we’ll see what will happen in November and what the negotiations bring.

DeBriefed 31 October 2025: Hurricane Melissa strikes Jamaica; Climate plans overshoot 1.5C; Protest crackdowns

The UK government has set out a long-awaited plan explaining how it will cut emissions in the 2030s, on its legally bound path to net-zero by the middle of the century.

Under the Climate Change Act, the government must lay out “carbon budgets” that set limits on the UK’s emissions over five-year periods.

In 2021, the government announced it would cut emissions by 78% by 2035 under its sixth carbon budget, but the “delivery plan” detailing how this would be achieved proved contentious.

The new “carbon budget and growth delivery plan” (CBGD) is the third draft, after the previous two delivery plans were successfully challenged in court.

Unlike previous versions, in this plan the government concludes that it has sufficient climate policies to achieve its sixth carbon budget and “96-99%” of its international obligations under the Paris Agreement.

This is in spite of the government scaling back its expectations for various climate policies, including clean-hydrogen production, tree-planting and carbon capture and storage (CCS).

The CBGD plan comes amid a fractured political consensus in the UK on climate action, with the Conservative party vowing to repeal the Climate Change Act and the hard-right Reform UK party repeatedly attacking net-zero.

Below, Carbon Brief gives an overview of the 363 pages of documents included in the plan, what it says about meeting UK emissions targets and what it means for individual sectors.

Why is there a new ‘carbon budget delivery plan’?

This is the third version of the sixth carbon budget delivery plan produced by the UK government, with the previous two having been ruled unlawful by the High Court.

The then-Conservative government passed the sixth carbon budget in 2021, legislating an emissions cut of 78% below 1990 levels by 2035. Carbon budgets are interim targets that act as “stepping stones” on the pathway to net-zero emissions by 2050.

However, in July 2022, the High Court ruled that the government had breached sections 13 and 14 of the Climate Change Act in adopting the delivery plan for the budget.

These sections refer to the government’s duty to prepare and adopt policies to meet its climate targets and publish on these policies so that parliament and the public can “scrutinise” them.

It ruled that the then-secretary of state Kwasi Kwarteng had “insufficient knowledge” to adopt the plan, as he did not know what emissions savings individual policies would be responsible for.

The plan also lacked “critical information” on a number of elements – for example, the reason for a shortfall in the emissions cuts, according to the claimants Friends of the Earth, ClientEarth and Good Law Project.

The High Court ordered the government to revise its strategy to correct these errors and a new plan was published in March 2023.

Once again, this was challenged in the High Court. The same claimants argued that the government did not consider “delivery risk” in a lawful way or publish sufficient information to allow meaningful scrutiny of its net-zero policies, among other breaches of sections 13 and 14.

In May 2024, the court sided with the claimants, finding that the secretary of state – by that time Claire Coutinho – had not been adequately informed about the delivery risks associated with the proposed policies. It also called for transparent, evidence-based policies to meet the carbon budget.

The government was given a new deadline of May 2025 to publish another version of the delivery plan. This was later extended to October 2025, as a result of last year’s general election.

Back to top

What does the new delivery plan say?

The new plan includes an overview document highlighting the government’s key political messages and a 238-page report laying out the details of expected emissions cuts.

The government emphasises how its policies will help the UK to “take back control of our energy” by expanding domestic renewables – cutting bills and boosting jobs in the process.

It also highlights how Labour’s climate plans will improve “quality of life and health”, plus help to “protect our natural environment”.

Other components of the delivery plan include a “technical annex” with details of modelling and accounting, an “investor prospectus” that outlines net-zero investment opportunities in the UK and a methane action plan, with sectoral plans for cutting the greenhouse gas.

The plan confirms that the government has all the climate policies in place to meet the UK’s fourth and fifth carbon budgets, covering the period 2023-2032.

Crucially, it also establishes that the government has enough extra policies in the pipeline to ensure 100% of the emissions cuts required for the sixth carbon budget are also achieved.

This is a step up from the plan released by the previous Conservative government, which only covered 97% of the cuts required for the period 2033-2037.

The new report explains that 76% of emissions cuts for the sixth carbon budget are covered by policies that have already been “implemented, adopted or planned”.

The remaining emissions cuts come from 169 additional proposals and policies that have been modelled by the government for the coming years, ranging from electrified steel plants to accelerated rates of tree-planting. The plan also accounts for another 12 “early-stage” proposals.

In addition to its domestic carbon-budget goals, the UK also has international climate targets under the Paris Agreement, known as nationally determined contributions (NDCs).

Unlike carbon budgets, which provide flexibility by allowing a set amount of emissions over a five-year period, the UK’s NDC goals involve specific emissions-reduction targets for single years, compared to a 1990 baseline.

The government calculates that its plans will cut emissions by 66% below 1990 levels by 2030 and 81% by 2035. These reductions are just shy of the UK’s NDC targets for 2030 and 2035 – representing 96% and 99% of the required cuts, respectively.

(Notably, the 2030 NDC target is more ambitious than the UK’s domestic climate target for that period, as the latter was set prior to the UK committing to net-zero emissions by 2050.)

In the delivery plan, the government says it will “seek to improve delivery and, where appropriate, will explore further measures, to ensure that the UK will meet its international commitments”.

The CBGD plan also considers the risk that government climate programmes underdeliver – for example, due to slow consumer uptake of low-carbon technologies.

Part of the legal case against the previous iteration of the plan was centred on its lack of adequate information about delivery risk. The new strategy appears to include a more extensive consideration of risk, stressing that there are “mechanisms in place to monitor and mitigate risks for each individual policy”.

It also states that the emissions savings for each policy are “credible” because, in cases where risks could not be avoided, the government revised down the emissions savings.

As a result, it concludes

“We, therefore, have confidence that each and every proposal and policy will deliver its planned scenario emissions savings.”

How does the new delivery plan meet the UK’s emissions targets?

The government’s CBGD plan lays out what it describes as a “credible level of emission savings”, enabling the UK to hit all of its upcoming domestic carbon budgets under the Climate Change Act.

Yet, a striking aspect of the plan is that the government has, in fact, significantly scaled back its expectations for several important sectors.

Government forecasts of low-carbon hydrogen production and peatland restoration are among the elements that have been downgraded since the 2023 plan. Expectations for biofuel-crop planting have also dropped to zero hectares in the near term.

Some of these policy areas have underperformed so far, such as tree-planting, or are less-established technologies, such as industrial carbon capture and storage (CCS).

These deployment assumptions have been highlighted in red in the table below. The relatively few sectors that have seen ambition ramped up are highlighted by Carbon Brief in green, while those that have remained steady since 2023 are grey.

The rolling back of expectations for key emissions-cutting policies raises the question of how the new plan can still put the UK on track to meet its sixth carbon budget, which covers the period 2033-2037.

First, the “baseline” emissions from which future reductions are calculated is considerably lower in 2025 than it was in the 2023 delivery plan.

This is largely because a set of policies that were previously “under development” have now been integrated into the baseline, as they are considered “implemented or developed”.

These include the zero-emissions vehicle (ZEV) mandate to encourage electric-car sales and the “sustainable aviation fuel” (SAF) mandate to drive the uptake of “clean” aviation fuels.

Together with some modelling adjustments, these changes reduced baseline emissions by 46.1m tonnes of carbon dioxide equivalent (MtCO2e) during the sixth carbon budget period. This shrinks the emissions gap that must be filled by upcoming climate policies and proposals.

Crucially, there are also three new categories of emissions savings that the Labour government has introduced, all of which further reduce this gap.

First, the government has captured the impact of various societal shifts that could affect decarbonisation, using the term “wider factors” to describe such changes. As an example, it mentions “developments in digital technologies including AI”.

Together, the plan states that these factors could “credibly” cut emissions by an extra 99MtCO2e in the sixth carbon budget period.

Second, the government also has a new category termed “other early-stage policies and proposals”. These are ideas deemed too preliminary to fully model, except for the sixth carbon budget period, during which the government estimates they could contribute an extra 43MtCO2e in emissions cuts.

Among these proposals are marine CO2 removals, saltmarsh restoration and policies to boost the market for “low-carbon industrial products”.

Finally, another 24MtCO2e over the sixth carbon budget period comes from what the government calls “cascade effects”. These “occur when changes in one system propagate through connected systems” – for example, when the uptake of net-zero technology becomes a “social norm”, the plan explains.

The combined impact of these three additional factors – none of which were considered in the 2023 plan – can be seen in the chart below.

Collectively, these components help to cut the remaining emissions during the sixth carbon budget period by 34MtCO2e, compared to the 2023 plan, in the government’s forecast. This is enough to meet the target, according to the government, rather than breaching it by 32MtCO2e as the previous plan did.

What does the delivery plan mean for the UK economy?

The CBGD plan includes an overview of how the government plans to make changes across different sectors of the economy, in order to bring down their emissions in the 2030s.

Transport

The transport sector continues to be the UK’s biggest source of emissions, accounting for 26% of the country’s total, the CBGD plan says. This figure rises to 35% when the UK’s contribution to international aviation and shipping is considered.

In 2023, road travel accounted for around 90% of domestic transport emissions, the plan continues, chiefly from journeys by petrol cars and vans.

After entering power in July 2024, the Labour government met a manifesto pledge to reinstate a 2030 ban on the sale of new petrol and diesel vehicles.

This target was originally set by the Conservative government under Boris Johnson’s leadership in 2020, but then delayed to 2035 by Rishi Sunak in 2023 as part of a wider rollback of net-zero policies.

Johnson’s government had also pledged to introduce a zero emissions vehicle (ZEV) mandate to set specific sales targets for car manufacturers in the lead up to the ban.

The ZEV mandate came into force in January 2024. Labour’s CBGD plan notes that it is “driving sales that made the UK Europe’s largest zero-emission car market in 2024 and the third largest globally”.

However, despite growing numbers of EVs on UK roads, the market is currently set to miss the ZEV mandate for 2025. In May, EVs accounted for 21.8% of new car registrations, below the 28% target set by the ZEV mandate.

In April this year, the government made some “tweaks” to the ZEV mandate, including introducing rules allowing manufacturers to count hybrid and plug-in hybrid vehicles towards their pure EV sales goals.

In a letter to the transport secretary, the Climate Change Committee warned that the changes “could encourage a greater role for hybrid vehicles and a reduction in emissions savings”.

In addition, Labour’s CBGD plan sets out less ambitious targets for the total proportion of ZEV cars on UK roads than previous strategies set out under the Conservatives in 2021 and 2023.

Namely, the CBGD plan sets targets of 21% of all cars being ZEV by 2030 and 48% by 2035. This compares to targets of 24% by 2030 and 53% by 2035 set under the 2021 net-zero strategy.

The government’s new CBGD plan notes that key risks to delivering its planned cuts to transport emissions include that “zero emission cars and vans do not displace their petrol and diesel counterparts at the rate we forecast”. This is as a result of lower than anticipated demand or “wider global supply chain challenges”.

Another key risk could be “unanticipated growth in travel demand”, with this being “most acute for our projections of emissions from cars, vans and air travel”, the plan says.

Commentators have noted a lack of new action in the plan to tackle emissions from rising demand for air travel in the UK.

Juliet Michaelson, director of climate charity Possible, said in a statement that the plan “still lacks realistic thinking on the most difficult to decarbonise areas, such as aviation”.

Colin Walker, head of transport at the Energy and Climate Intelligence Unit (ECIU), added that the government is continuing to “pin its hopes for cutting aviation emissions on sustainable aviation fuels and technological innovations that are still very much in their infancy”, while “failing to encourage ultra-frequent flyers from making more sustainable choices”.

Heat and buildings

Buildings remain one of the biggest sources of emissions in the UK, accounting for 74MtCO2e in 2023, or 17% of the country’s emissions.

This is predominantly due to the use of gas in heating systems, with 85% of UK homes using the fossil fuel to keep warm, according to the NGO Nesta.

However, efforts to decarbonise emissions from heating, in particular, have been viewed as contentious in some sections of the UK media, with outlets often referencing the “fury” of the public at policies dubbed “boiler bans” or “boiler taxes”.

One of the most significant policies to cut emissions in the sector is the “warm homes plan”, which the government is planning to publish “shortly”. The plan was set to be published in October, but is now expected after the autumn budget in November.

The scheme was first announced in spring 2025 by the newly appointed Labour government, with the goal of lifting more than a million households out of fuel poverty by 2030. During the spending review over the summer, the government said £13.2bn would be allocated to the scheme.

The policy is set to support the rollout of heat pumps and heat networks, alongside energy efficiency measures and other technologies, such as solar and batteries. More details are set to follow when the warm homes plan is published.

Beyond this, the CBGD plan includes other previously announced policies, such as the “boiler upgrade scheme”, which provides vouchers of up to £7,500 to support the rollout of heat pumps. The plan notes that the budget for this scheme has been almost doubled this financial year to £295 and funding will continue to increase each year up to 2029/30.

The delivery plan states that the government’s “vision is that, over the next decade, low-carbon solutions will become the natural choice for all households”.

It adds that, by the early 2030s, the government expects that more than one million existing homes will transition to low-carbon heating, as part of the “normal cycle of replacing an existing heating appliance (such as a gas boiler) at the end of its life”. By 2035, low-carbon heating will represent the majority of all heating-system replacements.

This new target seems to take over from the previous goal of 600,000 installations a year by 2028, which was included in the previous two versions of the CBGD plan. While the number of installations has been increasing, the UK has consistently fallen short of the level needed to meet this goal.

Additionally, the delivery plan removes the controversial “ban” on the sale of gas boilers in 2035, set under the previous Conservative government. The government notes that it will “continue to refine” its approach in coming years and consider additional interventions if needed.

The delivery plan’s technical annex notes that the modelling does not include any use of hydrogen for heating at present, but that the government will consult on it further in the future. It adds:

“As hydrogen is not yet a proven technology for home heating, any role would come much later and would likely be limited. If we conclude that hydrogen could play a role then some of the savings to be delivered by heat pump deployment in on gas grid homes could instead be delivered through hydrogen heating.”

Industry, CCS and hydrogen

In 2023, the UK’s industry emissions were 64MtCO2e, equivalent to 15% of total territorial emissions, the government says.

According to the CBGD plan, this represents a 12% decrease from 2019 levels and a 60% drop from 1990 levels.

The plan notes that the industrial sector “has a significant contribution to make to enable carbon budgets to be met”.

In June, the government set out a 10-year industry strategy, which it says aims to “drive long-term sustainable, inclusive and secure growth through securing investment into crucial sectors of the economy”.

The plan says that the government will also set out a “refreshed industrial decarbonisation plan”, which will “set the strategic direction for our approach to working with industry towards a competitive and low-carbon industrial base in the UK”.

It continues that the government is “looking at what could be delivered with further government action on resource and energy efficiency, fuel switching and CCUS [carbon, capture, utilisation and storage]”.

The plan says that the government is supporting fuel-switching and energy efficiency through its industrial energy transformation fund, which was launched in 2020 with plans to support the deployment of projects until 2028. (In July, the government confirmed that it is closing the fund to new applicants.)

In June, Miliband confirmed that £200m will be provided to progress the Acorn carbon capture and storage (CCS) scheme in Aberdeenshire, Scotland.

Despite this, the CBGD plan is less ambitious on both industrial resource efficiency and industrial CCS than previous net-zero strategies under the Conservatives in 2021 and 2023.

The government’s 2021 net-zero strategy set a target of industrial resource efficiency providing 11MtCO2e in savings by 2035. However, the CBGD plan has a target of just 5.4MtCO2e.

In addition, the 2021 net-zero strategy targeted 7MtCO2e of industrial CCS by 2035. The CBGD plan targets just 4.3MtCO2e.

The CBGD also cuts back a separate target for engineered greenhouse gas removal (GGR) techniques to provide 5MtCO2 in emissions savings by 2030, first made in the 2021 net-zero strategy.

(Engineered GGRs are technological methods for removing CO2 from the atmosphere, such as by using giant fans to suck the gas out of the air.)

The CBGD revises down this target to just 0.51MtCO2 a year from 2028-32.

Commenting on this decision, Prof Steve Smith, a GGR scientist at the University of Oxford, posted on LinkedIn, saying:

“This revision is reflective of the fact that little-to-no removal tech has actually been deployed in the UK since the 5Mt target was set. 2030 is really not far away in project development terms. We know from 20 years of experience with emission reductions that plans often fall behind (e.g. home insulation, CCS). Sensible strategy involves pursuing new technologies while being live to the risk of over-optimism in them.”

On hydrogen, the CBGD plan says the government is continuing to “support the rollout of hydrogen production to meet demand across sectors requiring hydrogen to decarbonise”.

It notes that, as part of the autumn 2024 budget, the government confirmed support for 11 green hydrogen projects and shortlisted another 27 projects for potential approval in April 2025.

However, the CBGD also significantly reduces ambition on clean hydrogen production, compared to previous net-zero strategies.

The CBGD targets 4 terawatt hours (TWh) of clean hydrogen production by 2030 and 24TWh by 2035. This compares to 40TWh by 2030 and 80-140TWh by 2035 under the 2021 net-zero strategy.

On LinkedIn, Harry Smith, an industrial emissions expert at the consultancy Aether, posted that the “deployment of low-carbon hydrogen no longer meets the 2030 targets set out in the 2021 UK hydrogen strategy”.

A new hydrogen strategy is due to be published this autumn.

Electricity

The power sector now makes up 10% of the UK’s emissions, accounting for around 44MtCO2e in 2023. Of this, gas combustion makes up around 75%.

Overall, the sector has decarbonised significantly, with CO2 emissions per unit of electricity falling by more than two-thirds in a decade, according to previous Carbon Brief analysis.

This is due to the rollout of renewable energy technologies and the closure of coal-fired power plants.

However, the UK has some of the most expensive electricity in the world. While this is due predominantly to gas prices – which set the wholesale cost of electricity 98% of the time – it remains a challenge for driving decarbonisation through electrification.

The cost of electricity in the UK is a key focus of the CBGD plan, which notes:

“The price disparity between electricity and gas needs to be addressed to make it more attractive for consumers to install clean technologies like heat pumps. Over this parliament, the government will be working relentlessly to translate the much cheaper wholesale costs of clean power into lower bills for consumers. This will be core to every decision we make. We will set out our plan in due course.”

The new CBGD plan does not include “rebalancing” the cost of gas bills relative to electricity, as the previous delivery plan did. It also does not consider shifting levies away from electricity bills.

Instead, the focus is broadly on the expansion of clean-power technologies, predominantly through pre-existing policies.

This includes investing in 80 power networks and enabling infrastructure projects, costing an estimated £40bn annually in the coming years. The plan recognises that the electricity network “must undergo unprecedented expansion”. (It is worth noting that, with or without net-zero targets in place, the UK’s grid would need constant investment and upgrades.)

The government also notes that it will work to “ensure appropriate planning arrangements, acceleration of grid connections and strong supply chains” to underpin this.

For example, the “strategic spatial energy plan” was commissioned to the National Energy System Operator in October 2024 and aims to “support a more actively planned approach” to electricity infrastructure.

The CBGD plan often points to the Clean Power 2030 Action Plan, published in December 2024, which set out the government’s approach to decarbonising the electricity sector by 2030.

It states that the government is investing “record amounts in clean energy, climate and nature”, including £63bn in capital funding.

The plan specifically highlights a final investment decision that was taken earlier this year to build Sizewell C nuclear power plant in Suffolk, with £14.2bn in funding allocated to the project. The government has also brought in reforms to the upcoming contracts for difference renewable energy subsidy auction to “maximise competition between bidders and reduce the costs to consumers”.

In addition, the first projects by the government’s new, publicly owned clean-energy company, Great British Energy, have also now been launched.

To support the rapid expansion of power-sector infrastructure, the plan notes that the “urgent need for change means we must undertake a wide-ranging reform programme”.

Finally, the plan notes that “hydrogen to power” has the “potential to play a key role” in the electricity system, along with other technologies that offer flexibility, such as power CCUS and energy storage.

Farming and land use

In 2023, agriculture and other land use accounted for 11% of the UK’s total greenhouse gas emissions, when international aviation and shipping is included, the CBGD plan says.

It adds that cow and sheep farming “currently make up the largest share of these emissions”.

The CBGD lists some of the government’s major policies for cutting emissions from agriculture and land use.

This includes the environment land management schemes (Elms), a post-Brexit project to pay farmers to cut CO2 emissions and protect nature on their land, first introduced by Boris Johnson’s government in 2020.

The CBGD plan says that “half of all farmed land” is now under Elms and that spending for the schemes will increase from £800m in 2023-24 to £2bn by 2028-29.

The National Farmers Union (NFU) has previously called the claim that spending had increased “misleading”, as farmers were originally promised a figure of £2.4bn a year from Elms after Brexit, the Guardian reported.

The largest of the Elms schemes is the sustainable farming initiative, the CBGD plan says.

In May, the government was forced to reverse a decision to close applications for the scheme after the NFU threatened legal action, according to Edie.

More widely, Labour’s plans to introduce an inheritance tax on farmers when businesses are worth more than £1m has caused mass protests across the country in recent months.

The CBGD plan revises down its deployment assumptions for the percentage of farmers taking up low-carbon practices, when compared to net-zero strategies from the Conservatives in 2021 and 2023.

Previous net-zero strategies set an assumption of 75% of farmers taking up low-carbon practices by 2030 and 85% by 2035. The CBGD sets assumptions of 67% by 2030 and 74% by 2035.

The Climate Change Committee has said the government must have a comprehensive plan for restoring peatlands if it is to meet the UK’s net-zero goal.

Healthy peatlands are carbon-rich habitats that support a range of species. However, some 80% of the UK’s peatlands are degraded, with the carbon they release accounting for 5% of the UK’s total greenhouse gas emissions.

The CBGD plan says that, under the Elms landscape recovery scheme, 35,000 hectares of peatlands will be restored, in addition to the 30,000 hectares targeted for restoration under a separate nature for climate peatland grant scheme.

However, the CBGD also revises down its deployment assumptions for peatland restoration, compared to previous net-zero strategies.

The 2021 net-zero strategy assumed that just over 10,000 hectares of peatlands would be restored in 2030. The CBGD plan has a lower figure of just under 8,000 hectares for the same date.

The CBGD plan also significantly revises down expectations for tree-planting, compared to previous strategies.

The 2021 net-zero strategy assumed that 40,000 hectares of new trees would be planted in 2030. The CBGD has a much lower number of 7,455 hectares for 2030.

Tom Cantillon, senior analyst at the Energy and Climate Intelligence Unit (ECIU), noted in a statement that the CBGD plan “seems to reduce ambition” on restoring peatlands and planting trees. He adds:

“With climate change worsening flooding in the UK, unless we work with nature by planting more trees and restoring habitats like peatlands to capture rainfall, people’s homes and farmers’ fields will be at ever greater risk.”

Key developments

China’s next ‘five-year plan’

NEW PLAN: The Chinese Communist party held its fourth plenum meeting, reported the Guardian, which described it as a “key meeting in the country’s political cycle and a crucial one in the development of its 15th ‘five-year plan’”. China’s “five-year plans” serve as blueprints guiding the country’s economic and social development. The 15th one runs from 2026-30. While the plan will not be released until next year, the full text of the official “adopting recommendations” said a “main target” will be making “major new progress in building a beautiful China”. This includes a “green production and lifestyle to be basically established [and] the carbon-peak target [for 2030] to be achieved as scheduled”, according to the text. 

TECHNOLOGY AND ‘INVOLUTION’: The Guardian’s report highlighted the “recommendations” for technology investments and a “crackdown on ‘involution’” – a reference to “fierce internal competition” that has, in the past, led to oversupply. In a “15th ‘five-year plan’ explanation” speech, Chinese president Xi Jinping said “it should be noted that the development of new quality productive forces”, which largely relies on technology, requires “full consideration of practical feasibility”, according to the transcript published by state news agency Xinhua. He also called on local officials to avoid a “rush” to develop projects, when talking about using technological innovation for “promoting a comprehensive green transformation”. 

‘GREEN’ TRANSITION: At a post-meeting press conference, Zheng Shanjie, head of the National Development and Reform Commission (NDRC), said the “comprehensive realisation of green transformation” requires the construction and implementation of the “dual control of carbon” system and the “green and low-carbon” transition of energy, as well as “industrial structure” and “production and lifestyle”. The National Energy Administration (NEA) also pledged to “focus on” building a “clean, low-carbon, safe and efficient new energy system” at a separate meeting, reported industry news outlet BJX News. Belinda Schäpe, China policy analyst from the Centre for Research on Energy and Clean Air (CREA), commented on LinkedIn that the commitment to build the “dual control of carbon” was “expected”. She added that the “reaffirmation” of renewable expansion was an “important signal given the uncertainty of the sector’s future after the policy pricing reform” came into force earlier this year. 

EXPERT REACTION: Schäpe called the mention of “[promoting the] peaking [of] coal and oil consumption” an “important signal”, as this is the first time “such language appears in a top-level planning document”. The oil-peak target “aligns with international expectations” and the “references to ‘clean and efficient use’ and ‘orderly replacement’ suggest a managed transformation of coal’s role – focusing on retrofits, flexibility and system support rather than new capacity growth”, she added. This suggestion of a peaking for coal and oil “allows” coal consumption to “increase in the early years of the five-year period”, according to a LinkedIn post by Lauri Myllyvirta, lead analyst from CREA. He said the peaking suggestion, although “in line with the goal of peaking [carbon dioxide] CO2 emissions before 2030”, provides “no guarantees of achieving a [CO2] reduction from 2025 to 2030, let alone starting from 2025”. The “most important question” for the next “five-year plan”, he added, is “whether China is committed to honouring the 2021 commitments: reducing carbon intensity by 65% from 2005 to 2030 and ‘gradually reducing coal consumption’” over the next five years. 

Pre-COP30 report

CLIMATE REPORT: The Chinese Ministry of Ecology and Environment (MEE) released an annual report on “China’s policies and actions on climate change 2025” ahead of COP30, reported the Chinese media outlet 21st Century Business Herald. The newspaper quoted Xia Yingxian, director of the MEE’s department of climate change, saying the report “showcased” China’s “significant contributions to mitigation, adaptation, carbon markets, carbon footprint, climate policies and regulations and leading global climate governance”. 

GLOBAL COOPERATION: The Paper, a Shanghai-based media outlet, reported that Xia said China “follows through” on its global climate cooperation commitments. Speaking about the 10th anniversary of the Paris Agreement, Chinese foreign minister Wang Yi said climate change has become an “urgent issue” and – in an apparent reference to the US – added that no country can “be a deserter”, according to a video posted by China News. Vice premier Ding Xuexiang also “said that China stands ready to work with all parties to advance global green development”, reported Xinhua. China’s stance on global climate cooperation was reiterated at a G20 environmental meeting in South Africa, according to International Energy Net. 

China-EU climate cooperation

FINANCE: The 21st Century Business Herald wrote that the MEE’s report indicated COP30 should make “positive progress” in meeting the financial targets agreed at COP29 – the “aspirational” target of $1.3tn a year and at least $300bn of climate finance a year by 2035. Xia said the $300bn pledge did not “fully reflect” the “capital contribution obligations of developed countries”, added the outlet. Meanwhile, the EU’s climate chief Wopke Hoekstra asked China to boost its climate-finance offering, reported European news website Euractiv. He said “China is an upper middle income country” and “Europe just simply does not have the pockets” to provide all the needed climate finance “by itself”, according to the outlet. 

CLIMATE TIES: In a press release following a recent meeting between Chinese premier Li Qiang and European Council president António Costa, Costa was quoted saying that “climate action has to remain [at the] top of our agendas” and that COP30 will “offer an opportunity for the EU and China to lead with ambition in order to achieve a successful outcome”. The Hong Kong-based South China Morning Post said Li also expressed Beijing’s willingness to work with the EU on matters including “the environment”. Costa added that “I shared my strong concern about China’s expanding export controls on critical raw materials”, urging Li to “restore as soon as possible fluid, reliable and predictable supply chains”, according to the press release. 

EXPORT CONTROLS: The trade dispute over China’s supply of rare earths was “settled” during a meeting between US president Donald Trump and his counterpart Xi in South Korea earlier today, reported the Guardian. Reuters said China agreed to delay the introduction of the next round of export controls, but that earlier restrictions on critical minerals will remain. The rare-earth minerals “play tiny, but vital roles” in products such as cars, planes and weapons, the newswire added. The US will also lower tariffs on some Chinese imports, according to ABC News.  

More wind, less coal

COAL DECLINE: Official data showed that China’s thermal power generation – mainly from coal – dropped 5.4% in September, reported Bloomberg. Meanwhile, the Ministry of Industry and Information Technology is consulting on its new steel capacity “swap” policy that aims to “promote market supply and demand balance”. Reuters said this was a “more stringent” swapping plan than the previous one that has been paused for 14 months. Shen Xinyi, researcher from CREA, explained on LinkedIn that the new programme “raises the replacement ratio to 1.5:1 nationwide” and encourages cross-regional swaps. She added the measures “signal a deeper shift: from expansion control to structural optimisation and decarbonisation”, calling it a “strategic move to restructure and rebalance China’s steel landscape”.

MORE WIND: A new industry proposal, the “Beijing Declaration on Wind Energy 2.0”, put forward a goal for the country’s wind capacity to reach “1.3 terawatts (TW) by 2030, at least 2TW by 2035 and a staggering 5TW by 2060”, said state-run newspaper China Daily. The outlet called the new plan a “significant increase” from an earlier declaration, which had targeted 3TW by 2060. The same group of wind-industry players are “lobbying the government to install at least 120 gigawatts (GW) of wind-power capacity in each of the next five years, an acceleration of the country’s energy transition that would more than double output by the end of the decade”, reported Bloomberg. The official goal is to install 3.6TW of capacity for wind and solar power combined by 2035, added the outlet. 

OVERSEAS EXPANSION: After two years of talk with the UK government, Chinese wind turbine manufacturer Ming Yang announced that it wants to build a £1.5bn project in Scotland, said BBC News. European governments, however, were “increasingly wary of Chinese companies’ involvement” in offshore wind, which is a “cornerstone of northern Europe’s clean-energy strategy”, reported Reuters. Exports of China’s other renewable energy products, namely, the “new three” – lithium-ion batteries, solar cells and electric vehicles (EVs) – rose nearly 40% year-on-year in September, according to official data, reported financial outlet Caixin. Separately, China “sent a clear signal that it is willing to pull the plug on subsidies” for the EV industry, said Reuters.

Q&A: How China is developing ‘vehicle-to-grid’ to strengthen its electricity system

China’s surging electric vehicles (EVs) ownership – now exceeding 25.5m – is opening the door to a new technology that turns EVs into “power banks” to help with the flexibility of electricity supply.  

Carbon Brief looks into the technology, known as “vehicle-to-grid” (V2G), and explains how it has sparked interest in China. The full article is available on Carbon Brief’s website. 

How can V2G help balance the grid?

In China, EVs with bidirectional batteries, when plugged into V2G-capable charging stations, are able to sell their stored electricity back to the grid in nine “pilot cities”, including Shanghai, Guangzhou and Shenzhen.

Dr Muyi Yang, senior electricity analyst at thinktank Ember, told Carbon Brief that a fleet of grid-connected EVs could help China achieve its broader plan to restructure its power sector towards a “new power system” that aims to be more flexible and responsive to power volatility. 

Zhou Xiaohang, China clean-power project manager at the US-registered Natural Resource Defense Council in Beijing, told Carbon Brief that, in the long run, V2G can help to address the curtailment issue for renewable energy, which is often referred to as the “Xiaona” problem in China. 

What is the current state of V2G adoption?

Currently, V2G has not been widely deployed in China. The cost of V2G infrastructure installation remains high.

Zhou said the success of large-scale roll out of V2G depends on whether there are enough EVs equipped with the bidirectional batteries and able to be plugged into V2G-capable charging stations.

China “already [has] enough EVs on the road to make [V2G] possible”, she added. 

Meanwhile, popular car brands such as BYD and Nio have released new EV models with V2G features and many more are actively testing and preparing for two-way electric charging.

There are 30 demonstration projects going on at the moment. Shenzhen, for example, received more than 70,000 kilowatt hours (kWh) of electricity from about 2,500 EVs in June.

Regional governments have also been working to introduce more profitable pricing systems to boost user participation.

Guangdong province, in south China, launched a V2G pricing plan that is “appealing” enough for EV owners to see a profit from participating in the scheme, according to Zhou.

What are the challenges in expansion?

A large share of China’s electricity is still traded through long-term power contracts, which could limit incentives for individual EV owners to engage in power-trading. 

Shen Xinyi, researcher at Centre for Research on Energy and Clean Air (CREA), told Carbon Brief: 

“Flexible systems like V2G and distributed solar power need a well-developed spot market and experienced, professional players such as power retailers to truly thrive.”

Zhou said whether V2G can be rolled out at scale also depends on the attitudes of consumers.

Chinese media outlet the Paper reported that people had expressed concerns on battery health and safety issues, including whether frequent discharges could cause battery degradation.

In April 2024, Hui Dong, chief technical expert at the China Electric Power Research Institute, a research institute affiliated to the State Grid Corporation of China, stated that, in terms of lifespan, chemical energy storage systems, represented by lithium-ion batteries, are still “underperforming”.

Watch, read, listen

CARBON REDUCTION: Prof Jiang Yi, director of building energy research centre at Tsinghua University, explained how to “reduce carbon” on both “the side of production” and “the side of consumption” in an interview with financial outlet Yicai. 

INDONESIA’S JOURNEY: The China Global South Project aired a podcast on China’s role  in “Indonesia’s push for clean energy and more coal”. 

CLIMATE STATEMENTS: China Daily published a list of climate statements from prominent Chinese politicians and researchers, including Liu Zhenmin, China special envoy for climate change. 

ENERGY CHALLENAGES: In a long interview with 21st Century Business Herald, Energy Foundation China president Zou Ji said “grid integration challenges” are the most “immediate obstacle” to China’s clean-energy buildout.

The growth in “added value” – a component of economic output – of China’s “green industries” from 2020-25, in Chinese yuan ($700bn), according to 21st Century Business Herald. The newspaper quoted Ren Yong, chief engineer at the Ministry of Ecology and Environment, saying that the “added value of green and low-carbon sectors in key industries” accounted for 8.3% of GDP in 2020 and is expected to rise to 11.7% in 2025, according to the newspaper. [Previous analysis for Carbon Brief found clean-energy industries accounted for 10% of China’s GDP in 2024.]

New science

Integrating scientific data, local knowledge and expert knowledge to assess climate vulnerability in fisheries

Ecology and Society

New research examined different approaches to assessing the vulnerability of fisheries to climate impacts, finding that using a data-driven approach can result in differing vulnerability than using a “knowledge-driven” one. The authors wrote that their results underline the “importance of engaging local knowledge to validate findings and provide contextualised interpretations for more effective management strategies”.

Mechanisms behind the rapid rise of extreme heat discomfort days in south China

Npj climate and atmospheric science

The number and strength of extreme heat discomfort days in south China has undergone a “sharp rise” since 2000, according to a new study. Researchers used observational weather data and a machine-learning model to determine the atmospheric circulation patterns that cause the extreme events. They found that an area of high pressure over the Pacific Ocean weakened the summer monsoon winds.
