Annual change in GHG emissions in the UK 2019-2023, by sector
Greenhouse gas emissions in the United Kingdom fell by an estimated 5.4 percent in 2023. UK electricity supply emissions dropped by almost 20 percent year-on-year to below 45 million metric tons of carbon dioxide equivalent (MtCO₂e). These reductions meant that the electricity supply sector emitted less than the agriculture sector for the first time. Only the fuel supply sector experienced emissions growth in 2023, at one percent.
