How this is measured
Source: Our World in Data, Global Carbon Budget. Values are the most recent non-empty observation for each country, so vintages differ; the year column carries each figure's own date rather than implying a single edition year. Territories appear where the source reports them and are labelled. See the methodology for refresh cadence, or the field definition for how the indicator is constructed.
