Only 64 countries have submitted new plans to cut carbon, the UN says, despite all being required to do so ahead of next month's COP30 summit. Added together, these national pledges would fail to keep the world from warming by more than 1.5C, a key threshold to very dangerous levels of climate change. While the UN review does show progress in curbing carbon emissions over the next decade, the projected fall is not enough to stop temperatures surging past this global target. The report underlines the scale of the task facing world leaders who head to Belém in northern Brazil next week for the COP30 climate gathering.
Ten years after the Paris climate pact was agreed in 2015, the efforts of countries to restrict the rise in global temperatures are under renewed scrutiny. Every signatory agreed to submit a new carbon-cutting plan every five years, covering the next decade. But only 64 countries managed to put a new pledge in place this year, despite many extensions of the deadline, representing around 30% of global emissions. The report shows that global emissions of carbon dioxide should fall by around 10% by 2035; however, scientists emphasize that such a drop is insufficient to keep the rise in temperatures under 1.5C. The UN warns that the thresholds will likely be breached permanently by the early 2030s unless robust action is taken at the COP30 summit.
