Global cumulative CO₂ emissions from fossil fuels and land use 1850-2022, by country

By the end of 2022, the United States had emitted about 550 billion metric tons of carbon dioxide (GtCO₂) since 1850, making it the largest contributor to global cumulative emissions by far. Nearly 427 GtCO₂ were emitted from fossil fuels, cement, and other industrial processes during this time, while land use released some 128 GtCO₂.

Since 1850, fossil fuels and cement production have accounted for the majority of cumulative emissions in countries such as Germany and the UK. In contrast, land use change has been the biggest contributor to emissions in countries such as Brazil and Indonesia. Both these countries clear vast areas of forest every year for pastures and plantations, which releases huge amounts of CO₂ into the atmosphere.
