National contributions to climate change due to historical emissions of carbon dioxide, methane and nitrous oxide. This dataset describes the global warming response to national emissions CO₂, CH₄ and N₂O from fossil and land use sources during 1851-2021. National CO₂ emissions data are collated from the Global Carbon Project (Andrew Per capita CO₂ emissions. Annual total emissions of carbon dioxide (CO₂), excluding land-use change, measured in tonnes per person. Source. Global Carbon Budget (2023); Population based on various sources (2023) – with major processing by Our World in Data. Last updated.
The European Union and the United Kingdom is the world’s third energy consumer and CO 2 emitter, accounting for 12% of global emissions 1,2,3.The EU27 announced the Green Deal in December 2019

In first place on the rankings, the US has released more than 509GtCO2 since 1850 and is responsible for the largest share of historical emissions, Carbon Brief analysis shows, with some 20% of the global total. Video shows, by ranked nation, cumulative CO2 emissions from fossil fuels, land use and forestry, 1850-2021 (million tonnes).
