Analysis
Tonga recorded 24,510 tonnes of CO₂ equivalents for greenhouse gas emissions by gas in 2024. That is the highest value across all 175 years on record.
The figure is up 0.8% on the previous year and up 11.5% over ten years.
Over the whole period, greenhouse gas emissions by gas in Tonga peaked at 24,510 tonnes of CO₂ equivalents in 2024 and was at its lowest, 784.63 tonnes of CO₂ equivalents, in 1850.
That places Tonga 181st out of 201 countries with data for 2024, putting it in the bottom quarter.
The series is highly variable year to year, so single readings are best treated with caution.
