Who has contributed most to global CO2 emissions?
Since 1751 the world has emitted over 1.5 trillion tonnes of CO2. To reach our climate goal of limiting average temperature rise to 2°C, the world needs to urgently reduce emissions.
- the United States has emitted more CO2 than any other country to date: at around 400 billion tonnes since 1751, it is responsible for 25% of historical emissions;
- this is twice more than China – the world’s second-largest national contributor;
- the 28 countries of the European Union (EU-28) – which are grouped together as they typically negotiate and set targets on a collaborative basis – is also a large historical contributor at 22%;
- many of the large annual emitters today – such as India and Brazil – are not large contributors in a historical context;
- Africa’s regional contribution – relative to its population size – has been very small. This is the result of very low per capita emissions – both historically and currently.
