Analysis
The most recent figure for greenhouse gas emissions in Tonga is 274,878 tonnes of CO₂ equivalents, measured in 2024.
Compared with earlier readings it is down 0.2% on the previous year and down 5.4% over ten years.
Over the whole period, greenhouse gas emissions in Tonga peaked at 312,726 tonnes of CO₂ equivalents in 2019 and was at its lowest, 38,650 tonnes of CO₂ equivalents, in 1870.
Tonga ranks 188th of 199 countries on this measure, in the bottom quarter.
The series is highly variable year to year, so single readings are best treated with caution.

About this data
Greenhouse gas emissions are measured in tonnes of carbon dioxide-equivalents over a 100-year timescale.
