The UK should make an international pledge to cut its greenhouse gas emissions to 81% below 1990 levels by 2035, according to the government’s advisory Climate Change Committee (CCC).
The recommendation for the UK’s next “nationally determined contribution” (NDC) under the Paris Agreement comes just weeks before the government is expected to announce its new target at the COP29 climate talks in Baku, Azerbaijan.
It follows a request from secretary of state Ed Miliband for guidance from the CCC, taking into account the levels of ambition set in the 2033-37 period covered by the “sixth carbon budget”.
Miliband also asked for the committee’s views on the impact of including, or not including, international aviation and shipping emissions. This mirrors the approach taken in 2020 for the UK’s previous NDC.
While the government is not obliged to follow the CCC’s advice, it has almost always done so in the past.
Such a target would be “ambitious, deliverable and consistent” with the UK’s legally binding sixth carbon budget, the CCC notes, providing a “credible contribution” towards limiting warming to 1.5C above pre-industrial levels.
Existing targets
Under the UK’s Climate Change Act, the government must set a long-term goal for cutting emissions by 2050, as well as five-yearly “carbon budgets” along the way.
The legally binding carbon budgets, detailing allowable levels of economy-wide emissions, are designed to provide “stepping stones” towards the 2050 goal.
When it was passed in 2008, the UK’s target was to cut greenhouse gas emissions to 60% below 1990 levels by 2050, but this was quickly increased to 80%.
The UK’s first five carbon budgets, covering the period from 2008 through to 2032, were set in the context of that 80% by 2050 goal.
However, in 2019, the Conservative prime minister Theresa May raised the UK’s long-term goal to a 100% reduction by 2050, commonly referred to as “net-zero”.
After the UK officially left the European Union in 2020, the increased ambition of the net-zero target provided the context for the UK’s first NDC, which pledges to cut emissions to “at least 68%” below 1990 levels by 2030 – excluding emissions from international aviation and shipping (IAS), in line with UN convention.
(This is more ambitious than the fifth carbon budget target of a 57% reduction between 2028 and 2032, which was set under the lower 80% by 2050 goal.)
Subsequently, in 2021, the Conservative government “enshrined” the UK’s sixth carbon budget in law, targeting a 78% cut in emissions during 2033-2037. This budget was also set in line with the new net-zero target.
In addition, the sixth carbon budget includes the UK’s share of international aviation and shipping for the first time, “in line with the CCC’s long-held view that all UK carbon budgets should account for emissions from both sources”.
The CCC recommends that the budget should be set at 965m tonnes of CO2 equivalent (MtCO2e) for the period 2033 to 2037. This equates to, on average, 193MtCO2e annually. In 2019, annual emissions stood at 522MtCO2e.
It evaluated the potential level of the target under different scopes, including noting that changes to the methods it uses for estimating UK emissions could lead to higher estimates for both historical and future emissions. These “higher inventory changes” were taken into account for the 78% target.
If international aviation and shipping are excluded, but the higher inventory changes remain, the CCC’s recommended emissions reduction by 2035, on the basis of 1990, is 82%.
According to independent research group Climate Action Tracker (CAT), the UK’s NDC pledge to reduce emissions by 68% below 1990 levels is “almost sufficient”. It notes that, while the UK’s current target is not consistent with limiting warming to 1.5C, it could be with “moderate improvements”.
CAT had previously rated the target as compatible with 1.5C in 2022, but it has since updated its modelled pathways “to reflect the latest science”. This resulted in more stringent reductions being needed to get on track.
NDC recommendations
The CCC has recommended that the UK’s next NDC commits to reducing territorial emissions by 81% from 1990 to 2035, as shown in the chart below, based on the committee’s forthcoming advice on the seventh carbon budget.
Such a reduction would be consistent with the UK’s existing net-zero-aligned targets: the 2030 NDC; the sixth carbon budget; and net-zero by 2050.
Meeting the 2035 recommendation and the adopted 2030 NDC will require “rapid, but achievable action with low-carbon technologies becoming mainstream”, the CCC states. It points to the 10 recommendations made in its progress report, released earlier this year.
These include making electricity cheaper, reversing policy rollbacks seen under the previous Conservative government and removing planning barriers for technologies, such as heat pumps, EV chargers and onshore wind.
In a statement accompanying the CCC’s letter, Prof Piers Forster, interim chair of the committee, said:
“The technologies needed to achieve it are available, at a competitive price, today. Investment in low-carbon technologies – electric vehicles, heat pumps and renewables – needs to come now for this target to be achievable. Businesses will start to invest when they have confidence in what the government’s long-term policy plans are. We need to see the government’s commitment to climate reflected in the upcoming budget.”
The CCC has provided its NDC recommendation excluding emissions from international aviation and shipping, “in line with UNFCCC convention”, it notes.
If they were included, the committee’s recommendation would sit at 77-78% – almost the same as the level set in the sixth carbon budget.
Most NDCs historically have not included international aviation and shipping. This is consistent with the Paris Agreement, which excluded emissions from these sectors due to the difficulty in attributing emissions to individual countries.
Instead, emissions from these sections are addressed under the International Civil Aviation Organisation and the International Maritime Organisation.
While international aviation and shipping have, therefore, not been included within the CCC’s recommendation for the UK’s 2035 NDC, it notes that the UK is “well-positioned to drive international aviation and shipping decarbonisation”.
Stronger action is “urgently needed” to address international aviation and shipping emissions, the CCC says, which are expected to be the third largest source of emissions in the UK by 2035 and the second by 2050 (after agriculture).
The CCC notes that there have been some accounting changes since the release of the sixth carbon budget. As such, the UK emissions inventory has been revised to lower some estimates for the country’s total greenhouse gas emissions.
This means that the amount of emissions reduction required to meet the sixth carbon budget is now “slightly smaller” – falling from 78% to 77% as noted above.
This has led to some small differences between the percentage reduction required to meet the legislated sixth carbon budget target and those recommended by the CCC in its advice in 2020, as shown in the table below.
| 2035 UK emissions reduction excluding IAS (NDC basis) |
2035 UK emissions reduction including IAS |
|
| CCC NDC recommendation (based on forthcoming CB7 pathway) |
81% | 77-78% |
| CCC CB6 advice | 82% | 77-78% |
| CB6 legislated basis (comparing annualised legislated CB6 number with latest inventory estimate of 1990 emissions) | 80% | 77% |
Source: CCC analysis.
As such, the CCC’s NDC recommendation for 2035 is 81%, while the sixth carbon budget advice was 82%. The actual amount of emissions reduction does not change, remaining at 965MtCO2e for the period 2033 to 2037.
The delivery plan for the NDC should be aligned with the UK’s international and domestic goals on nature, the CCC adds. It should also be fully integrated with the forthcoming National Biodiversity Strategy and Action Plan to the UN Convention on Biological Diversity.
Additional advice for the UK’s wider contribution to tackling climate change includes strengthening the UK’s national adaptation programme, supporting climate finance and “championing international transparency” by submitting a best practice NDC technical annex.
The UK should “strengthen and contribute to key international initiatives”, such as the global methane pledge. However, the CCC notes that international credits should not be used to achieve any NDC.
What happens next?
All parties within the Paris Agreement are expected to communicate their NDCs at least 9-12 months ahead of the relevant COPs. For the upcoming 2035 NDC, this means parties must submit their targets between November 2024 and February 2025.
Speaking at the UN general assembly in September, prime minister Keir Starmer said the UK would:
“Meet our net-zero target, backed up with an ambitious NDC at COP29, consistent with limiting warming to 1.5C, and we’ll support others to do the same.”
As such, Carbon Brief understands that it is likely Starmer will unveil the UK’s NDC on the first day of COP29 during the leaders summit.
Prof Forster, adds:
“More than any commitment, what we really need is action. I have no doubt that the UK can once again be a leader on the international stage – in both deeds and words.”
Other nations are also likely to publish their NDCs in the coming months, including the US, COP28 host the UAE, COP29 host Azerbaijan and upcoming COP30 host Brazil.
These NDCs will “form the foundation of international climate action”, according to the World Resources Institute. They will be presented and adopted at COP30 in late 2025.
Underlying its NDC advice is the CCC’s work on the seventh carbon budget, its recommendations for which will be published on 26 February 2025. This will cover the period from 2038 to 2042.

Whale Entanglements in Fishing Gear Surge Off U.S. West Coast During Marine Heatwaves
New research finds that rising ocean temperatures are shrinking cool-water feeding grounds, pushing humpbacks into gear-heavy waters near shore. Scientists say ocean forecasting tool could help fisheries reduce the risk.
Each spring, humpback whales start to feed off the coast of California and Oregon on dense schools of anchovies, sardines and krill—prey sustained by cool, nutrient-rich water that seasonal winds draw up from the deep ocean.

Key developments
Food inflation on the rise
DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.
‘TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.
El Niño looms
NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”
WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”
CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.
News and views
- DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
- SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
- NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted.
- COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
- FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.”
- TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.
Spotlight
Nature talks inch forward
This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.
The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.
The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).
However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.
The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.
Money talks
Finance for nature has long been a sticking point at negotiations under the CBD.
Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.
Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.
Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).
Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:
“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”
Monitoring and reporting
Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.
Parties do so through the submission of national reports.
Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.
A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.
Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:
“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”
Watch, read, listen
NET LOSS: Nigeria’s marine life is being “threatened” by “ghost gear” – nets and other fishing equipment discarded in the ocean – said Dialogue Earth.
COMEBACK CAUSALITY: A Vox long-read looked at whether Costa Rica’s “payments for ecosystem services” programme helped the country turn a corner on deforestation.
HOMEGROWN GOALS: A Straits Times podcast discussed whether import-dependent Singapore can afford to shelve its goal to produce 30% of its food locally by 2030.
‘RUSTING’ RIVERS: The Financial Times took a closer look at a “strange new force blighting the [Arctic] landscape”: rivers turning rust-orange due to global warming.
