Analysis
Singapore recorded 1.34 million tonnes of CO₂ equivalents for nitrous oxide emissions in 2024.
The figure is up 0.7% on the previous year and up 11.5% over ten years.
Over the whole period, nitrous oxide emissions in Singapore peaked at 10.58 million tonnes of CO₂ equivalents in 1998 and was at its lowest, 22,820 tonnes of CO₂ equivalents, in 1850.
Singapore ranks 133rd of 201 countries on this measure, in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.
