Analysis
Cambodia recorded 471,188 tonnes for year-on-year change in co₂ emissions in 2024.
Compared with earlier readings it is down 13.8% on the previous year and down 56.2% over ten years.
Over the whole period, year-on-year change in co₂ emissions in Cambodia peaked at 4.69 million tonnes in 2019 and was at its lowest, -934,320 tonnes, in 1971.
That places Cambodia 53rd out of 215 countries with data for 2024, putting it in the top quarter.
The series is highly variable year to year, so single readings are best treated with caution.
