Analysis
The most recent figure for carbon intensity of energy in Singapore is 52.77 grams of CO₂ per kilowatt-hour, measured in 2024.
Compared with earlier readings it is up 0.1% on the previous year and down 3.5% over ten years.
Over the whole period, carbon intensity of energy in Singapore peaked at 315.31 grams of CO₂ per kilowatt-hour in 1979 and was at its lowest, 8.75 grams of CO₂ per kilowatt-hour, in 1966.
That places Singapore 201st out of 204 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.
