How this figure is calculated

Cumulative CO₂ emissions divided by GDP (current US$), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.

Cumulative CO₂ emissions ÷ GDP (current US$)

Computed from

Cumulative CO₂ emissions Global Carbon Budget (2025) – with major processing by Our World in Data
GDP Country official statistics, National Statistical Organizations and/or Central Banks

Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
