When we emit carbon dioxide (CO2) into the atmosphere, most of it stays there for centuries or millennia. This means that CO2 emitted even a century ago has contributed to the rising temperatures we see today.
In other words, how much the climate warms depends on how much cumulative CO2 is emitted over time.
The chart shows the ten countries with the largest share of the world’s historical emissions, based on cumulative emissions from fossil fuels and industry since 1750.
The United States has contributed the most, accounting for almost one quarter. This is followed by China and Russia.
Where this page came from
This page was imported from Our World in Data. “Which countries have contributed the most to historical CO₂ emissions?” by Hannah Ritchie, published by Our World in Data under CC BY 4.0. Changed here: set as a page, its interactive charts shown as pictures. Data from third parties keeps its own licence.
Nobody has written it yet — it is the source material at a new address, which is why search engines are asked to skip it and why no one earns from it. It is up for grabs: take it on, and it is yours to rewrite and to earn from.
