World's climate pledges would cut emissions a tenth of what's needed: UN

The latest climate pledges from nations will only reduce global greenhouse gas emissions by six percent by 2035, according to a UN report. This is significantly lower than the 60 percent reduction from 2019 levels needed to limit warming to 1.5°C, according to scientists. The report analyzed 154 countries' nationally determined contributions (NDCs) - obligations under the 2015 Paris deal - received between January 2024 and August 2026, covering 71 percent of global emissions.

Even if countries fully implement their plans and meet conditional targets, emissions cuts would still only amount to nine percent. The United States, under President Donald Trump, has left the Paris Agreement for a second time, favoring policies that heavily rely on fossil fuels. The next UN climate talks in Türkiye, COP31, can address some key implementation gaps, according to UN climate chief Simon Stiell.
