The distribution of regional cumulative carbon dioxide emissions has changed dramatically since 1750. For many decades the vast majority of emissions were produced in countries in Europe, specifically Great Britain, where the Industrial Revolution originated. As the United States began to emerge as a global power, the distribution of emissions changed. By the start of the twentieth century, the United States accounted for almost a quarter of cumulative emissions, and by the 1950s its share had increased to almost ** percent. With cumulative emissions of more than *** billion metric tons of COâ‚‚, the United States is the biggest emitter in history.

China is now the second-biggest historical emitter, having seen its share of cumulative emissions grow from less than *** percent in 1990 to more than ** percent by the end of 2023.
