Analysis
In 2024, greenhouse gas emissions in Cook Islands stood at 88,295 tonnes of CO₂ equivalents.
Compared with earlier readings it is up 3.8% on the previous year and down 2.1% over ten years.
Over the whole period, greenhouse gas emissions in Cook Islands peaked at 90,226 tonnes of CO₂ equivalents in 2014 and was at its lowest, 3,855 tonnes of CO₂ equivalents, in 1850.
That places Cook Islands 195th out of 199 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.

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