The tables above focused on carbon dioxide (CO ₂ ). CO ₂ however, it is not the only greenhouse gas. Others, including methane and nitrous oxide, have so far had a significant effect on global warming.

The first interactive graph shows greenhouse gas emissions per inhabitant . It is measured as the sum of all greenhouse gases and is given by a metric called "carbon dioxide equivalents".

"Carbon dioxide equivalents" attempt to correct for the fact that one unit (eg a tonne) of a given gas does not have the same warming effect as another. We therefore multiply the emissions of each gas by its "Global Warming Potential" (GWP): this value measures the amount of warming that one tonne of that gas would produce in relation to one tonne of CO ₂ .

Another interactive graph shows where these emissions come from: the contribution of each sector. (More on ourworldindata.org)
