GHG emissions progress and projections in the EU-27 2005-2030, by sector

Greenhouse gas emissions from the European Union's energy supply sector fell roughly 40 percent between 2005 and 2022, to an estimated 902 million metric tons of carbon dioxide equivalent (MtCO₂e). It is projected that with additional national policies and measures, EU energy supply emissions in 2030 could drop to roughly 500 MtCO₂e. Emissions from the transportation sector, which is the second-largest source of EU emissions, are projected to drop to 639 MtCO₂e with additional measures. The EU has a net GHG emissions reduction target of 55 percent below 1990 levels by 2030.

欧洲联盟能源供应领域的温室气体排放量在2005年至2022年间大约下降了40%，降至约9.02亿吨二氧化碳当量（MtCO₂e）。预计在采取额外的国家政策和措施后，到2030年，欧盟能源供应领域的排放量可能降至约500亿吨二氧化碳当量。作为欧盟排放量第二大来源的交通领域的排放量，在采取额外措施的情况下预计将降至639亿吨二氧化碳当量。欧盟设定了到2030年将温室气体净排放量较1990年水平减少55%的目标。
