CO2 emissions by country – ranked

A global ranking of CO2 emissions by country, measured by metric tons per capita, using the latest data available from the World Bank.

Carbon dioxide (CO2) is the primary greenhouse gas emitted as a result of human activity. Greenhouse gases such as carbon dioxide, methane (CH4), nitrous oxide (N2O) and fluorinated gases trap heat and make the Earth warmer.

Carbon dioxide emissions

Carbon dioxide is naturally present in the atmosphere as part of the Earth’s natural circulation of carbon between the atmosphere, oceans, soil, plants, and animals.

However, human activity – especially fossil-fuel combustion – is responsible for virtually all of the increase in greenhouse gases in the atmosphere over the last 150 years.

Carbon dioxide (CO2) accounts for the most significant share of greenhouse gases, which are associated with global warming and climate change. Emissions largely originate from the burning of fossil fuels and the manufacture of cement.

The data from the World Bank does come with a caveat. The carbon dioxide emissions of a country per capita are only an indicator of one greenhouse gas.

For a more comprehensive view of how a country and its population impact climate change, gases such as methane and nitrous oxide should also be considered. This is especially relevant in agricultural economies.
