Half of global greenhouse gas emissions are now covered by a 2035 climate pledge following a key UN summit this week, Carbon Brief analysis finds.
China stole the show at the UN climate summit held in New York on 24 September, announcing a pledge to cut greenhouse gas emissions to 7-10% below peak levels by 2035.
However, other major emitters also came forward with new climate-pledge announcements at the event, including the world’s fourth biggest emitter, Russia, and Turkey.
Following the summit, around one-third (63) of countries have now announced or submitted their 2035 climate pledges, known as “nationally determined contributions” (NDCs).
The NDCs are a formal five-yearly requirement under the “ratchet mechanism” of the Paris Agreement, the landmark deal to keep temperatures well-below 2C, with aspirations to keep to 1.5C, by the end of this century.
Nations were meant to have submitted these pledges by 10 February of this year, but around 95% of countries missed this deadline.
UN climate chief Simon Stiell then asked laggard countries to make 2035 pledges by the end of September, so they can be included in a report synthesising countries’ climate progress.
At the summit, many nations shared that they were still working on their NDCs and that they would aim to submit them to the UN before or during COP30 in November.
Halfway there
The map below shows countries that submitted their 2035 pledges by the 10 February deadline (dark blue), after the deadline (blue) and that have now announced their pledge, but not yet submitted it formally to the UN registry (pale blue).
The EU has not yet agreed on a 2035 climate pledge. At the UN climate summit, European Commission president Ursula von der Leyen announced a “statement of intent” to cut emissions somewhere in the range of 66.3-72.5% below 1990 levels by 2035.
She added that the EU would aim to make its formal NDC submission to the UN before COP30 in November.
The world’s second-largest emitter, the US, submitted its 2035 pledge in 2024 under former president Joe Biden.
However, current president Donald Trump has since signed an order to withdraw the country from the Paris Agreement. Therefore, it is now assumed that the US pledge is now void.
More than 100 nations spoke at the UN climate summit, which was held on the margins of the annual UN general assembly in New York.
Some media outlets mistakenly reported that all of these countries “announced” new pledges at the summit.
However, many of the countries speaking at the summit had already submitted their 2035 pledges, or used their slots to promise to do so at a future date.
Carbon Brief reviewed the six hours of footage from the UN climate summit to get a clear picture of which countries announced new 2035 pledges during the event.
Countries that made new NDC target announcements during the event included China, Russia, Turkey, Palau, Tuvalu, Kyrgyzstan, Peru, São Tomé and Príncipe, Fiji, Bangladesh and Eritrea. (Tuvalu has since submitted its NDC to the UN.)
These countries together represent 36% of global greenhouse gas emissions, according to Carbon Brief analysis. (It is worth noting that China alone accounts for 29% of emissions.)
Some 53 countries have already submitted their 2035 climate pledges to the UN Framework Convention on Climate Change (UNFCCC). These nations account for 14% of global greenhouse gas emissions.
Therefore, countries that have either announced or submitted their 2035 climate pledges now represent half of global emissions, according to Carbon Brief analysis. (The 50% figure excludes the US and the EU for the reasons outlined above.)
Missing emitters
Despite the new announcements, two-thirds of nations have still not submitted their 2035 climate pledges, according to Carbon Brief analysis.
This includes major emitters, such as India, Indonesia and Mexico.
According to the Hindu, India plans to submit its 2035 climate pledge at the beginning of COP30 on 10 November.
Both Mexico and Indonesia spoke at the UN climate summit. Mexico said it was “still consulting industries” about its proposed target, while Indonesia made no mention of when it might submit its NDC.
Many other nations appearing at the summit made promises to submit their 2035 climate pledges by COP30.
This might mean that many nations miss the end of September deadline set by UN climate chief Simon Stiell to be included in an upcoming NDC synthesis report.

Trump Administration Dropped Controversial Climate Report From Its Decision to Rescind EPA Endangerment Finding
The final EPA rule explicitly omitted the report commissioned last year to justify revoking the endangerment finding, citing “concerns raised by some commenters.”
When the U.S. Environmental Protection Agency rescinded its bedrock endangerment finding Thursday, it explicitly excluded a controversial report issued last year by the U.S. Department of Energy that argued the dangers of human-induced climate change were being overstated.
Tailpipe standards meant to hasten adoption of electric vehicles were slashed alongside the scientific basis for regulating greenhouse gas emissions. That will come at a cost.
With the repeal of the Environmental Protection Agency’s scientific finding on the dangers of greenhouse gases, the Trump administration is aiming to take out many federal actions on climate change in one blast.

A doubling of fish biomass along Asia’s longest river shows hope for large-scale conservation efforts and a lifeline for the endangered finless porpoise.
Flowing almost 4,000 miles from the Tibetan Plateau to the East China Sea, the Yangtze is China’s “Mother River.” From the emerald-green rice paddies of Hunan to the industrial hubs of Wuhan and Shanghai, the river basin generates 40 percent of the nation’s economic output. Yet, 70 years of rapid development had, until recently, wreaked havoc on its delicate marine ecosystem.
