Rail transportation CO₂ emissions in the EU-27 1990-2022

Rail transportation in the European Union produced 3.3 million metric tons of carbon dioxide (MtCO₂) in 2022, a decrease of eight percent from the previous year. Since 1990, EU railway CO₂ emissions have fallen by more than 70 percent. Trains are one of the least polluting modes of transportation available, and account for less than one percent of EU transportation GHG emissions.

欧盟铁路运输在2022年产生了330万吨二氧化碳（MtCO₂），较上一年度下降了8%。自1990年以来，欧盟铁路的二氧化碳排放量已减少超过70%。铁路运输是污染程度最低的交通方式之一，其温室气体排放量仅占欧盟交通运输总排放量的不到1%。
