CO₂ emissions per capita, 2017

Per capita carbon dioxide emissions were derived by Our World in Data based on four datasets:

1. Long historical estimates of annual carbon dioxide emissions from the Carbon Dioxide Information Analysis Centre (CDIAC)
2. Production and consumption-based estimates of CO2 emissions from the Global Carbon Project
3. Long-run population estimates by country, sourced from Gapminder & UN Population estimates
4. Long-run global population estimates from the HYDE Database

Per capita emissions (production-based) were calculated by diving total national CO₂ emissions per year by population estimates.

CO2 data has been converted from tonnes of carbon to tonnes of carbon dioxide (CO₂) using a conversion factor of 3.664.
