The UK’s greenhouse gas emissions fell by 2.4% in 2025 to their lowest level in more than 150 years, according to new Carbon Brief analysis.

The biggest factors were gas use falling to a 34-year low and coal use dropping to levels last seen in 1600, when Queen Elizabeth I was on the throne and William Shakespeare was writing Hamlet.

These shifts were helped by record-high UK temperatures, elevated gas prices, the end of coal power in late 2024 and a sharp slowdown in the steel industry.

Other key findings of the analysis include:

  • The UK’s greenhouse gas emissions fell to 364m tonnes of carbon dioxide equivalent (MtCO2e) in 2025, the lowest level since 1872.
  • Coal use roughly halved, with more than half of this due to the end of coal power and another third due to closures and other issues in the steel industry.
  • Gas use fell by 1.5% to the lowest level since 1992, with roughly equal contributions from cuts in heat for buildings and industry, more than offsetting a small rise in gas power.
  • Oil use fell by 0.9%, despite rising traffic, helped by more than 700,000 new electric vehicles (EVs), electric vans and plug-in hybrids on the nation’s roads.
  • The UK’s emissions are now 54% below 1990 levels, while its GDP has nearly doubled.

The 2.4% (8.9MtCO2e) fall in emissions in 2025 was only slightly more than half of the 15MtCO2e cut needed each year on average until 2050, to reach the UK’s legally binding net-zero target.

The analysis is the latest in a decade-long series of annual estimates from Carbon Brief, covering emissions during 2024, 2023, 2022, 2020, 2019, 2018, 2017, 2016, 2015 and 2014.

Emissions fall to 150-year low

The UK’s territorial greenhouse gas emissions – those that occur within the country’s borders – have now fallen in 27 of the 36 years since 1990.

(The recent fall in territorial emissions has not been “offset” by a rise in the amount of CO2 embedded in imports, which has stayed relatively constant since around 2008.)

Apart from brief rebounds after the global financial crisis and the Covid-19 lockdowns, UK emissions have fallen every year for the past two decades.

The latest 9MtCO2e (2.4%) reduction takes UK emissions down to 364MtCO2e, according to Carbon Brief’s analysis, which is 54% below 1990 levels.

This is the lowest since 1872, as shown in the figure below.

The latest fall puts UK emissions below the level seen during the 1926 general strike, when the nation’s industrial base was brought to a standstill.

It means that UK emissions are now at sustained lows not seen since Victorian times.

Nevertheless, emissions will need to continue falling in order to meet the UK’s legal climate goals and its net-zero target, which is part of international efforts under the Paris Agreement to stop dangerous warming.

Record lows for coal and gas

The key factors in driving down UK emissions in 2025 were coal and gas use falling to their lowest levels since 1600 and 1992, respectively.

For gas, this was mainly down to lower demand from building heat and from industry, likely at least partly related to record-high temperatures and elevated gas prices. For coal, this was a combination of the end of coal power and a steel-industry slowdown, as shown below.

These were not the only factors driving the change in UK emissions in 2025.

The UK saw record generation from renewable sources, particularly wind and solar, but a further decline in nuclear generation, the end of coal power and an increase in electricity demand for the second year running meant that gas-fired power output also went up slightly.

In the transport sector, demand for oil fell by 0.9% year-on-year, even though traffic levels went up by around 1%, according to provisional figures through to September 2025.

This partly reflects the changing makeup of vehicles on the road.

By 2024, there were 2.8m fewer diesel vehicles than there were in 2019, a trend likely to continue due to falling diesel car sales. In contrast, there are now nearly 3m EVs, plug-in hybrids or electric vans on the nation’s roads, making up 5% of the car fleet overall and 2% of vans.

These electrified vehicles are cutting UK emissions by more than 7MtCO2 every year, according to Carbon Brief analysis, with the 700,000 new EVs in 2025 alone saving nearly 2MtCO2.

Drivers with EVs saved a total of £2m in lower fuel costs in 2025, the analysis shows, as EVs are much more efficient and, therefore, cheaper to run than petrol or diesel vehicles. This amounts to more than £700 per EV per year and more than £1,100 for each electric van.

Despite falling demand for oil-derived fuels and the impact of the growing EV fleet, Carbon Brief estimates that the UK’s oil-related emissions actually increased by 0.2% in 2025. This is largely down to a shift in the amount and type of biofuel blended into diesel and petrol at the pump.

Coal falls to lowest level in 400 years

There have been dramatic declines in UK coal use over the past decade, in particular resulting from the phaseout of coal-fired electricity generation.

UK coal demand fell by another 56% in 2025 to just under 1m tonnes (Mt). This is down 97% from the 37Mt burned in 2015 and is 99.6% below the peak of 221Mt in 1956.

As shown in the figure below, coal demand is now at the lowest level since 1600, when Elizabeth I was the queen of England and Ireland.

(It was during her five-decade reign that coal had become the country’s main source of fuel, following an Elizabethan “energy crisis” triggered by a lack of wood for making charcoal.)

The UK’s last coal-fired power plant, at Ratcliffe-on-Soar in Nottinghamshire, closed down on 30 September 2024. It had run at low levels that year, but still burned some 0.7m tonnes of coal. The end of coal power contributed nearly three-fifths of the fall in demand for the fuel in 2025.

There has also been a marked reduction in UK steel production in recent years, particularly since the closure of two of the nation’s last blast furnaces at Port Talbot in south Wales in 2024.

The last blast furnaces in the country are at the British Steel plant in Scunthorpe in Lincolnshire, which had been due for closure in early 2025 until the government stepped in to keep it open.

The slowdown in coal-based steel production accounts for around a third of the decline in UK coal use in 2025, but only 14% of the drop in the past decade, which was mainly due to coal power.

Globally, the steel industry is facing intense competition in an oversupplied market, with a growing “glut” that has driven down prices. At the same time, the industry in the UK has ageing equipment and expensive electricity, which UK Steel says is largely a result of high gas prices.

The Port Talbot site is being converted to “electric arc furnace” (EAF) steelmaking, which does not rely on coal. The same shift is under discussion for the Scunthorpe site. Analysis from thinktank Green Alliance suggests EAFs would be the cheapest option for both sites.

Gas falls to lowest level in 34 years

There have also been dramatic declines in UK demand for gas over the past 15 years. After another 1.5% drop in 2025, gas use is now at the lowest level since 1992, as shown below.

This means gas demand is now similar to when the UK began its “dash for gas” in the early 1990s. Starting in 1991, this period saw a wave of new gas-fired power stations being built. It was triggered by a change in regulations to allow the use of gas to generate electricity, advances in turbine technology, a period of low gas prices and the privatisation of the UK electricity system.

In total, UK gas demand has fallen by nearly two-fifths since 2010. Half of this overall reduction is due to a 50% fall in gas-fired electricity generation, which has been displaced by falling demand and renewable sources. Another third of the overall reduction is from home heating, where demand has dropped due to more efficient gas boilers and improved insulation.

In 2025, the 1.5% reduction in gas use was caused by roughly equal contributions from lower demand for building heat and from industrial users.

This was helped by 2025 being the hottest year on record, with high gas prices likely also a factor.

Gas prices have remained significantly above the levels seen before Russia’s invasion of Ukraine in 2022. At the start of March 2026, UK gas prices roughly doubled as a result of the conflict in the Middle East triggered by the US and Israeli attacks on Iran.

Whereas the UK’s fleet of EVs is already having a significant impact on emissions, domestic heat pump sales remain at relatively low levels, particularly compared with other European nations.

After a 25% year-on-year increase in 2025, there were still only 125,000 heat pump sales in the UK. These new installations will have cut UK emissions by around 0.2MtCO2 in 2025 relative to gas heating, shows Carbon Brief analysis.

By the end of 2025, the UK had a total of around 450,000 domestic heat pumps, generating total savings of roughly 0.7MtCO2 after accounting for the increase in electricity demand.

The 2.3m domestic heat pumps expected by 2030 in the National Energy System Operator’sfuture energy scenarios” would save the UK around 4.5MtCO2 per year.

Emissions continue to decouple from growth

In total, UK greenhouse gas emissions in 2025 fell to 54% below 1990 levels, the baseline year for its legally binding climate goals.

Since then, the UK economy has nearly doubled in size, with GDP growing by 95% according to data from the World Bank, as shown in the figure below.

Chart showing that UK emissions are 54% below 1990 while economy has nearly doubled
Change since 1990, %, in UK greenhouse gas emissions (red) and GDP adjusted for inflation (blue). Source: Carbon Brief analysis of figures from DESNZ and the World Bank.

Transport remains the single-largest sector, accounting for around 30% of UK emissions, followed, in order, by buildings, agriculture, industry and electricity generation.

The majority of emissions cuts over recent decades have come in the power sector – formerly, the UK’s largest emitter – as coal has been phased out and renewables have replaced gas.

This is set to change over the next 10-15 years. The rise of EVs is set to make transport the largest source of emissions cuts from now until 2040, according to the Climate Change Committee.

While industrial emissions have also declined significantly since 1990, falling some 74% by 2025, the size of UK manufacturing output has also roughly doubled.

Despite the progress in cutting emissions to date, the UK has a long way to go if it is to meet its climate goals in the future, including the yet-to-be legislated seventh “carbon budget”, covering the years 2038-2042, as well as the 2050 net-zero target.

Emissions would need to fall by 15MtCO2e each year until 2050 on average, in order to meet the net-zero target. Meeting the UK’s 2035 international pledge under the Paris Agreement, a 78% reduction below 1990 levels, emissions would need to fall by 22MtCO2e per year.

These figures can be compared with the 9MtCO2e cut achieved in 2025. Emissions did, in fact, fall by an average of 15MtCO2e per year over the past decade – and by an average of 13MtCO2e per year since the turn of the century.

Methodology

The starting point for Carbon Brief’s analysis of UK greenhouse gas emissions is preliminary government estimates of energy use by fuel. These are published monthly, with the final month of each year appearing in figures published at the end of the following February. The same approach has accurately estimated year-to-year changes in emissions in previous years (see table, below).

2011 -7.2 -7.7 -0.4

2023 -5.0 -5.2 -0.2
2024 -2.7 -3.0 -0.3
2025 -2.4

One large source of uncertainty is the provisional energy use data, which is revised at the end of March each year and often again later on.

Emissions data is also subject to revision in light of improvements in data collection and the methodology used, with major revisions in 2021 and more minor changes in early 2026.

The latest changes to the DESNZ emissions methodology have led to 2% reduction in baseline 1990 emissions, but the impact on recent years is minimal.

This does not affect the UK’s carbon budgets, which are set in terms of tonnes of emissions over a five-year period, rather than a percentage reduction compared with 1990 levels.

The table above applies Carbon Brief’s emissions calculations to the comparable energy use and emissions figures, which may differ from those published previously.

Another source of uncertainty is the fact that Carbon Brief’s approach to estimating the annual change in emissions differs from the methodology used for the government’s own provisional estimates. The government has access to more granular data not available for public use.

Carbon Brief’s analysis takes figures on the amount of energy sourced from coal, oil and gas reported in Energy Trends 1.2. These figures are combined with conversion factors for the CO2 emissions per unit of energy, published annually by the UK government. Conversion factors are available for each fuel type, for example, petrol, diesel, gas and coal for electricity generation.

For oil, the analysis also draws on Energy Trends 3.13, which further breaks down demand according to the subtype of oil, for example, petrol, jet fuel and so on. Similarly, for coal, the analysis draws on Energy Trends 2.6, which breaks down solid fuel use by subtype.

Emissions from each fuel are then estimated from the energy use multiplied by the conversion factor, weighted by the relative proportions for each fuel subtype.

For example, the UK uses roughly 50m tonnes of oil equivalent (Mtoe) in the form of oil products, around half of which is from road diesel. So half the total energy use from oil is combined with the conversion factor for road diesel, another one-fifth for petrol and so on.

Energy use from each fossil fuel subtype is mapped onto the appropriate emissions conversion factor. In some cases, there is no direct read-across, in which case the nearest appropriate substitute is used. For example, energy use listed as “bitumen” is mapped to “processed fuel oils – residual oil”. Similarly, solid fuel used by “other conversion industries” is mapped to “petroleum coke” and “other” solid fuel use is mapped to “coal (domestic)”.

The energy use figures are calculated on an inland consumption basis, meaning they include bunkers consumed in the UK for international transport by air and sea. In contrast, national emissions inventories exclude international aviation and shipping.

The analysis, therefore, estimates and removes the part of oil use that is due to the UK’s share of international aviation. It draws on the UK’s final greenhouse gas emissions inventory, which breaks emissions down by sector and reports the total for domestic aviation.

This domestic emissions figure is compared with the estimated emissions due to jet fuel use overall, based on the appropriate conversion factor. The analysis assumes that domestic aviation’s share of emissions is equivalent to its share of jet fuel energy use.

In addition to estimating CO2 emissions from fossil fuel use, Carbon Brief assumes that CO2 emissions from non-fuel sources, such as land-use change and forestry, are the same as a year earlier. The remaining greenhouse gas emissions are assumed to change in line with the latest government energy and emissions projections.

These assumptions are based on the UK government’s own methodology for preliminary greenhouse gas emissions estimates, published in 2019.

Note that the figures in this article are for emissions within the UK measured according to international guidelines. This means they exclude emissions associated with imported goods, including imported biomass, as well as the UK’s share of international aviation and shipping.

The Office for National Statistics (ONS) has published detailed comparisons between various approaches to calculating UK emissions, on a territorial, consumption, “environmental accounts” or “international accounting” basis.

The UK’s consumption-based CO2 emissions increased between 1990 and 2007. Since then, however, they have fallen by a similar number of tonnes as emissions within the UK.

Bioenergy is a significant source of renewable energy in the UK and its climate benefits are disputed. Contrary to public perception, however, only around one-quarter of bioenergy is imported.

International aviation is considered part of the UK’s carbon budgets and faces the prospect of tighter limits on its CO2 emissions. The international shipping sector has a target to at least halve its emissions by 2050, relative to 2008 levels.

China’s industrial engine starts to break its fossil fuel habit

Published

on

Chinese industry is beginning to shift from fossil fuels to clean electricity, with wind, solar and batteries progressively displacing coal, oil and gas across the industrial sectors that made the country the world’s factory and largest carbon emitter, a new analysis shows.

Clean electricity met all of China’s demand growth in 2025 and coal generation fell for the first time in a decade, even as electricity demand rose by 5%, the report found.

Despite a rebound in coal power generation in the first half of 2026, the analysis by global energy think-tank Ember found the growth in clean electricity illustrates a longer-term shift: a massive build-out of wind, solar energy and battery storage and deepening electrification of the economy are starting to make a dent in the fossil-fuel energy system supporting China’s industrial base.

China keeps Indonesia’s battery dream afloat but future less certain

The research identifies early signs that a structural transformation of China’s industrial economy from coal, oil and gas to clean electricity is underway, even if changes on the ground are not yet reflected in national data.  

“The energy foundation of the Chinese industrial economy is shifting,” Muyi Yang, a senior energy analyst at Ember and the report’s lead author, told Climate Home News.

“Fossil fuels are progressively being replaced in the many functions they have historically assumed. Because of that, fossil fuel peaking is increasingly coming into view,” he said.

Electrifying industry

Coal generation has stopped growing in 17 of the 26 provinces and regions analysed by Ember between 2021 and 2025. This includes industrial centres such as Hunan in southern China and Shandong – home to energy-intensive industries like cement production. Together, these regions are home to more than half of China’s thermal power capacity.

A greater share of the Chinese economy is now running on electricity than in other major economies, accounting for 29% of final energy consumption in 2024, compared with about 23% in Europe and 21% in the US. Less than half of China’s electricity was generated from coal in the first half of the year.

    Meanwhile, fossil fuel use has fallen in eight of 11 tracked industrial sectors, declining between 26% and 71% from peak consumption levels across fossil fuel extraction, manufacturing industries such as textiles, machinery and food and beverages, transport equipment and chemical materials.

    Earlier this year, German company BASF, the world’s largest chemical producer, opened a new facility in southern China, which is fully supplied by renewable energy. The company said emissions from the site could be 50% lower than conventional petrochemical facilities.

    In easier-to-electrify sectors such as machinery, electronics and textiles, electricity now supplies about three-quarters of final energy consumption, Ember found.

    Fossil fuel use is also showing signs of flattening in the metals smelting and processing sector – one of the most fossil-intensive parts of the economy – offering “encouraging signs” that the transformation is starting to take hold in harder-to-abate sectors, said Yang.

    “If that is happening in more and more provinces, and more and more economic sectors that means that fossil fuels are progressively being squeezed out of the energy system,” he said.

    “Growing by greening”

    China’s vast cleantech manufacturing power has become an engine for growth in its own right, spurring investment, creating jobs and generating export revenues.

    Yang described this “growing-by-greening” dynamic as “turning each step of the transition into a source of strength for the next”.

    China and Brazil join pledge to triple global nuclear energy capacity

    For Li Shuo, director of China Climate Hub at the Asia Society Policy Institute, this is part of what makes China’s lead in manufacturing clean energy equipment “irreversible”, comparing its growth with that of a rainforest, where different parts of the ecosystem thrive by reinforcing one another.

    The early success of deploying wind and solar helped drive down electricity costs, which created favourable conditions for the rapid adoption of electric vehicles (EVs) and in turn boosted demand for batteries that are now critical to balance the grid.

    An oversupply of renewable energy incentivised industrial players to benefit from cheap and readily available clean power generation, encouraging innovative solutions to electrify other parts of the economy. In the transport sector, for example, electrification is moving from passenger vehicles to harder-to-electrify trucks.

    This abundance of cheap green energy is also making China competitive in what has long been seen as the anchor of Western competitiveness, Li said.

    Stalling fossil fuel use

    At the same time, China’s huge legacy fossil fuel generation capacity is still expanding, even as coal power plants are being used less intensively.

    China brought 30 GW of new coal power capacity into operation in the first six months of the year and coal-fired generation rose 3% over the same period after local governments fast-tracked coal projects to prevent a repeat of severe power shortages in 2021.

    Solar surge kept fossil electricity flat in 2025 as China and India made ‘historic’ shift

    A further 274 GW of coal capacity is either under construction or has permits to be built while vast amounts of solar and wind power that could not be absorbed by the grid have gone to waste in the first half of the year.

    “This doesn’t mean that the transition is losing steam,” said Yang, arguing that China is now grappling with some of the more complex aspects of the transition.

    A recent analysis by the Centre for Research on Energy and Clean Air (CREA) for Carbon Brief found that China’s CO2 emissions from fossil fuels and cement have plateaued for more than two years following a peak in March 2024. Ember found that on a 12-month moving average, coal generation has been stalling since then, following years of continuous expansion.

      In the second quarter of the year, CO2 emissions fell by 1% after China’s oil consumption plummeted 9% as the US-Iran war prevented the transport of oil cargoes from the Gulf through the Strait of Hormuz.

      The electrification of the transport sector, particularly electric trucks, was the biggest driver in displacing oil demand as the conflict in the Middle East accelerated the transition.

      A lesson in sequencing

      China’s bumpy transition offers a useful lesson for other countries at an earlier stage of their transition, said Xunpeng Shi, president of the Sydney-based International Society of Energy Transition Studies (ISETS), a global network of professionals that shares research and fosters collaborations.

      “Build quickly enough so that clean electricity can start taking over and prepare for the pressure on the fossil system before it arrives, because that is the part nobody has done easily,” he said.

      For countries that are heavily reliant on revenue from fossil fuel exports, a peak in Chinese fossil fuel use weakens the assumption of rising demand on which investments have long been made.

      “For them, the time to plan for that is now, while the revenues are still there,” he said.

      Industry and NGOs lobby to weaken UN carbon credit rules in “coordinated” push

      Published

      on

      Carbon credit developers, corporate buyers and some leading conservation NGOs are challenging new proposed rules to stop UN carbon credits being wiped out by fire, drought or logging, in what critics have called a “coordinated lobbying campaign” to weaken the nascent market’s push for greater integrity.

      According to documents seen by Climate Home News – including a briefing given to government officials – companies, NGOs and the UN Environment Programme (UNEP) have contested the scientific basis for the move, arguing that stronger protection for carbon reductions could hike project costs and restrict the supply of credits to the market.

      The climate benefit of credits that claim to reduce or avoid greenhouse gas emissions by storing carbon is undone if that carbon is released back into the atmosphere – something known as reversal risk. To protect against such losses and preserve the credibility of the credits’ carbon-offsetting claims, projects are generally required to set aside a reserve of credits that cannot be sold, as a form of insurance.

      How these “buffer pools” are calculated has long been a source of contention, especially in forest conservation projects, which many experts say have historically underestimated the risk of carbon losses.

      In July, the technical UN panel tasked with drafting rules for the Article 6.4 mechanism, which underpins the credits that countries and companies can use to meet their climate goals, proposed a new system. It would require project developers to size these insurance pools of credits based on local risk values derived from new research published by a group of independent scientists.

      UK’s budget juggling trick with rainforest loan for bus-fare cap needs transparency

      Its supporters have hailed it as a more rigorous approach than current practice in the voluntary carbon market, which largely relies on expert guesswork and, in some cases, gives significant leeway for project developers to come up with their own data.

      “The decision on the reversal risk assessment tool will be crucial,” said Federica Dossi, an expert at Brussels-based advocacy group Carbon Market Watch. “It would bring a new paradigm for calculating the number of units forwarded to the buffer pool based on empirical data.”

      The technical panel is due to discuss the reversal risk tool and its application to a specific set of projects at a five-day meeting in Bonn this week. It is then expected to forward new recommendations to the mechanism’s regulator, the Supervisory Body, for a decision on whether to approve them at a meeting in early October.

      The rules are set to be applied initially only to clean cookstove projects, one of the market’s most popular and heavily criticised credit types. They could then be extended to other activities, including programmes to protect forests.

      Copy and paste?

      More than 30 organisations aired their views in lengthy public submissions to the Article 6.4 mechanism, responding to a call from the UN secretariat for external feedback.

      A Climate Home News review of those submissions found that there was significant overlap in their messages and, in several cases, sections of the text, or even entire submissions, were copied and pasted by different organisations. This points to a coordinated effort to flag concerns regarding the new rules.

      In one instance, tech giant Apple, a large buyer of nature-based carbon credits, warned against relying on one scientific model and called for rules that let project developers use a variety of risk mitigation tools, rather than surrendering buffer credits, to cover the risk of carbon losses.

      Apple’s submission is a lightly-edited version of a separate input presented by the Beyond Alliance, a coalition of corporate buyers and NGOs that promote market-based climate investments. In an apparent oversight in one paragraph, the Beyond Alliance’s name appears in Apple’s submission instead of the tech giant’s.

        The Beyond Alliance told Climate Home News that, after receiving input from its members, it shared its final submission, leaving them to decide if and how they wanted to use it. The coalition rejected any characterisation that its submission advocates for a weaker tool and only reflects business concerns.

        The Beyond Alliance added that its members received briefings by UNEP, which Climate Home News understands has played an important role in wider efforts to influence the development of the rules underpinning the UN carbon market.

        Three experts and a European Union diplomat told Climate Home News that the interventions of the UN agency overwhelmingly supported the views of those with a financial interest in carbon markets.

        UNEP’s head of mitigation Gabriel Labbate rejected this accusation. He told Climate Home News that the UN agency contributes technical inputs from a “politically-neutral, science-based perspective” and its positions are grounded in an assessment of environmental integrity and are not shaped by, or aligned with, the financial interests of any market participant. 

        UNEP, NGOs criticise scientific basis

        In mid-July, representatives from UNEP, Conservation International and The Nature Conservancy (TNC) briefed government officials from Canada, the UK, Germany, Costa Rica, Belgium, Nigeria and Peru, according to a webinar readout seen by Climate Home News.

        The online event was organised by the Forest & Climate Leaders Partnership (FCLP), an initiative that brings together 41 countries plus the EU.

        The speakers voiced strong criticism of the new proposed rules. A technical advisor to Conservation International, a US-based NGO that runs several large-scale carbon offsetting programmes, told participants the Article 6 panel’s approach was “based on bad science”. This, he said, is because it relies on a single model that he claimed is not appropriate to determine buffer pool contributions, according to a presentation seen by Climate Home News.

        During a high-level discussion led by UNEP’s Labbate, speakers said the application of measures to manage reversal risk on cookstove projects could “impose disproportionate costs and undermine the financial viability of these activities”, according to the readout.

        Cookstove programmes issue credits by calculating the greenhouse gas emissions prevented by burning less fuel – usually wood or charcoal – through the use of more efficient stoves. With the new reversal risk tool, these activities would be expected to guard against future carbon losses for the first time under the UN carbon market.

        But UNEP, as well as leading NGOs and carbon credit firms, have pushed back against the requirement, arguing this type of credit represents a “flow” of avoided emissions rather than a “stock” of stored carbon that can be released. Scientists reject that distinction, noting that the wood left unburned is still standing in a forest exposed to the same risks as any other.

        At the online briefing, speakers also raised concerns that the tighter approach would be replicated for nature-based carbon projects with a direct impact on the future of large-scale forest conservation credits. The Conservation International advisor called it a “bad precedent”.

        Both Conservation International and TNC run carbon credit programmes that aim to protect trees from being cut down. Labbate leads the UN-REDD programme, which supports countries developing forest protection initiatives including through carbon credits, and is co-chair of the expert panel advising the Integrity Council for the Voluntary Carbon Market (ICVCM).

        After the webinar, the organisers shared by email a series of “key messages” and draft submissions produced by the three organisations, which participants were invited to consider and adapt in their own inputs to the Article 6.4 consultation process.

        Getting the rules ‘right’

        In a statement to Climate Home News, Ghana, Paraguay and the UK – which are FCLP co-leads for its work on forest carbon credits – said members of the coalition welcomed expert views from a range of partners to help them understand the potential impact of Article 6.4 rules on the eligibility of forest carbon credits in international markets.

        They added that the FCLP does not have a common position on the rules and its members are free to choose whether to attend webinars and use any of the materials circulated.

        In a statement to Climate Home News, Conservation International said “getting these rules right is important to the environmental integrity of the carbon market, while ensuring all sectors have a place in it”. It added that the NGO does not dispute the validity of the scientific research underlying the proposed buffer pool, but recommends a broader approach including multiple models and datasets.

        A spokesperson for TNC said the organisation had helped clarify complex materials and their potential implications, while decisions on how to respond remained entirely with participating countries.

        ‘Inconvenient science’

        The scientific basis for the disputed reversal risk tool rests on two pieces of research. A peer-reviewed study, published in Nature in May and led by scientists at several US universities, modelled forest carbon-loss risk across the United States and found existing buffer pools there are undersized by an average factor of six.

        To extend that approach worldwide, the Article 6.4 panel also drew on a second, global analysis by the same research team, which has not yet completed peer review. That study used satellite images, weather records and computer modelling to estimate a 31-42% chance of forests worldwide losing stored carbon within 100 years, depending on the scenario.

        The panel picked one of these scenarios and turned its estimates into fixed risk percentages for individual countries, and in some cases provinces, which projects in those locations would need to apply.

        Critics say the peer-reviewed portion of the research was calibrated on North American forests, and that applying the same approach to other regions relies on a global study that is still going through academic checks.

        But, for William Anderegg, professor of biological sciences at the University of Utah and one of the authors of that research, it is the best science currently available. He described it as “light-years better” than assumptions underlying the voluntary carbon market, where risk numbers are not generally based on independent evidence and tend to be incredibly low.

        Scientific research, including by Anderegg, has found that buffer pools in forestry projects in the voluntary carbon market are substantially smaller than they should be to adequately protect against future releases of carbon.

        “There really seems to be a fairly coordinated campaign to try to weaken the strength of these [Article 6.4] tools and their scientific underpinning,” he told Climate Home News. “It’s a little dispiriting to see folks attack science that’s inconvenient.”

        Regulators under pressure?

        An EU diplomat told Climate Home News that experts and negotiators working on the Article 6.4 mechanism have faced intense pressure from big carbon credit developers and large parts of the nature-based solutions community.

        “It is very clear that they are lobbying against strong rules, and they want to align the Paris Agreement mechanism with the standards of the voluntary carbon market,” the diplomat said. “They have influence, time and money, even more than some governments, so they can be very effective in their efforts.”

        Last year, the Article 6.4 Supervisory Body, the new market’s regulator, approved rules on the permanence of credits aiming to remove carbon from the atmosphere which critics said were watered down compared to the technical panel’s recommendations. This followed feedback from carbon market firms and conservation NGOs, which submitted dozens of critical views.

        Carbon Market Watch’s Dossi said decisions that strengthen environmental integrity are targeted in particular as they tend to reduce the number of credits that can be issued.

        Then, as now, those who opposed tighter rules argued that overly strict safeguards would make some projects too expensive to carry out, with a negative impact on local communities and the climate.

        But proponents argue that higher-integrity programmes will drive up market prices, ultimately benefiting everyone.

        “If rules ensuring better-quality credits make them somewhat more expensive than they are today, that’s an acceptable consequence, not a reason to weaken the rules, especially since these credits will be used to offset continued emissions,” said Dossi.

        Efforts to pull the rule-makers in different directions are expected to intensify in the coming weeks as a decision on the new credit protection system nears.

        “I really don’t know how this will turn out in the end,” one veteran carbon market expert said. “What I am sure about is that it will be quite a battle.”

        London talks raise hopes for green shipping deal

        Published

        on

        A relatively ambitious deal to reduce the shipping industry’s 3% of global emissions now looks more likely after four days of closed-door talks in London, observers say.

        The International Maritime Organization (IMO), which oversees the negotiations, said there had been “constructive discussions” and “genuine willingness within the group to make concrete further progress”.

        Em Fenton, senior director at the NGO Opportunity Green who attended the talks last week, said they “demonstrated a strong spirit of solidarity in the face of blatant attempts to undermine the credibility, ambition and equity of a hard-fought multilateral agreement”.

        After several years of debate, governments provisionally agreed in April 2025 on a “Net-Zero Framework” (NZF) – a series of emissions reduction targets for shipowners aimed at incentivising them to use cleaner fuels, backed up with financial rewards for meeting the targets and fees for missing them.

        But in October 2025, after a high-profile intervention by US President Donald Trump and threats of US sanctions and visa restrictions, the US convinced a majority of voting nations to postpone the adoption of the NZF for a year.

        UCL analysis found that, of those who expressed a view at last week’s talks, 38 were in favour of an NZF-style solution while only 17 were against. Those opposed are “consistently composed of strongly fossil fuel-aligned governments”.

        An observer of the talks, who did not want to be named, said the countries opposed include the US, Russia, India, Thailand, Argentina, Ecuador and Uruguay, as well as eight oil-rich Gulf nations and shipowner-reliant Liberia and Panama. Governments that support an NZF-style deal include China, Brazil, Mexico, Türkiye, Canada, Australia, Chile, nine African nations, most European countries and small islands.

        A new framework to tackle shipping emissions could be adopted if two-thirds of countries that are present and signed up to a regulation called Marpol Annex VI – endorsed by just over 100 states – vote in favour of it, as they did in April 2025.

        UCL’s analysis said it was “reassuring” that governments which had taken strong positions in the media against the NZF were being more compromising in the negotiations.

        Tweaks are probable

        While there is majority support for the NZF, UCL said adopting it would be difficult politically. “The process from here could therefore be as much about producing what appears to be a new package, but one that broadly ends up with similar outcomes in relation to objectives,” UCL argued.

        But tweaking the NZF, which resulted from years of negotiations, comes with risks, it warned. For example, changes could reduce the new system’s planned support for low-income countries, turning them against it. Fenton said compromising should not mean “abandoning the principle of justice in the maritime transition”.

        UCL said the speed at which shipowners must reduce their ships’ emissions or face fees is likely to be reduced in the short-term but raised in the long-term to meet a goal of net zero emissions by mid-century.

          This was a compromise put forward by NZF-supporter Brazil. However, an analysis by the the Institute of Marine Engineering, Science and Technology (IMarEST) has found that this change would lead to more overall emissions than the original NZF trajectory.

          UCL has warned it could incentivise liquefied natural gas as a shipping fuel over greener options, which include hydrogen-based methanol and ammonia.

          Analysis by UCL and the Rocky Mountain Institute suggests that, while a slower start to the NZF would reduce transport costs in the short term, it would increase them later due to the costs involved in switching the industry over from more polluting fuel to cleaner fuel.

          NZF won’t meet emissions goals

          IMarEst’s analysis finds that even in its current form – the most ambitious deal on the table – the NZF will not be sufficient for shipping to meet its emissions reduction goals.

          It says that only a Pacific proposal to place a levy on ships’ total emissions – rather than just those above a certain level – would meet the industry’s targets to reduce emissions 20% between 2008 and 2030, 70% by 2040 and then reach net zero “by or around, i.e. close to 2050”. This is highly unlikely to be adopted.

          Additional talks will be held from November 23-27 and from November 30-December 3 before a potentially final round of official negotiations begins on December 4.
