MtCO 2 e UK Methane (CH 4 ) Emissions
UK Methane (CH 4 ) Emissions
Overall, UK methane emissions decreased by 3.9% to 51.3 MtCO 2 e in 2020. The most significant year-on-year change to UK methane emissions came from the transport sector, which saw a 21.3% decrease. Again, due to lower demand across the economy, methane emissions decreased in all sectors, including agriculture, which previously saw an annual average increase in emissions of 0.1% between 2010 and 2019. Despite increasing usage of natural gas for electricity generation, methane emissions from the energy sector have decreased by 69.5% since 2000. The transport sector is a minor contributor to UK methane emissions – accounting for only 0.15% (76.5 ktCO 2 e) of emissions. Of this small portion, 88% comes from the road segment, while shipping emits another 8.4%. Including the 21.5% decrease in road segment methane emissions in 2020, road methane emissions have decreased by 90% since 2000, largely as a result of turnover in the car fleet. Methane emissions from shipping have increased by 26% since 2000 (including an 11.4% decrease in 2020). Please note that these statistics are presented in ktCO 2 e.
