Global greenhouse gas (GHG) emissions reached a record high of 55bn t/CO2 equivalent (CO2e) in 2025, up by 0.9pc on the year, data from the EU’s independent emissions database for global atmospheric research (Edgar) show. These figures include the land use, land use change and forestry (LULUCF) sector — which can act either as a source of carbon or a carbon sink. Excluding LULUCF, global GHG emissions rose to 54.1bn t/CO2e in 2025, an increase of 0.7pc on the year, Edgar found. The highest-emitting countries in 2025 were China, the US and India, with shares of 29.5pc, 11.1pc and 8.3pc of the global total, respectively, Edgar data show. …Of the top six emitters, the US and Indonesia recorded the most substantial increases in emissions in 2024-5 — a rise of 2.2pc or 131.5mn t/CO2e for the US and one of 1.2pc or 16.1mn t/CO2e for Indonesia.
