CO2 emissions in 2020 were 0.124 megatons, making Tonga is in the group of low-polluting countries, mainly due to its small population, within the ranking of countries for CO2 emissions, made up of 184 countries, in which the countries are ranked from least to most pollutant.

In addition to its total emissions of CO2 into the atmospher, which logically depend, among other variables, on the country's population, it is convenient to analyze the behavior of its emissions per inhabitant.
