In 2021, net greenhouse gas (GHG) emissions in the United Kingdom (UK) were 427 million tonnes (Mt) carbon dioxide equivalent (CO2e), 80% of which was carbon dioxide (CO2) itself. Emissions increased by 5% in 2021 with the easing of COVID-19 restrictions, primarily due to the extra road transport. The UK has over time emitted about 3% of the world total human caused CO2, with a current rate under 1%, although the population is less than 1%.Emissions decreased in the 2010s due to the closure of almost all coal-fired power stations. In 2020 emissions per person were somewhat over 6 tonnes when measured by the international standard production based greenhouse gas inventory, near the global average. But consumption based emissions include GHG due to imports and aviation so are much larger, about 10 tonnes per person per year.The UK has committed to carbon neutrality by 2050 and the Energy and Climate Intelligence Unit has said it would be affordable. The target for 2030 is a 68% reduction compared...
