Analysis
Singapore recorded 239,968 tonnes for emissions of air pollutants in 2022.
That represents a change of up 1.4% on the previous year and down 7.1% over ten years.
Over the whole period, emissions of air pollutants in Singapore peaked at 268,689 tonnes in 2017 and was at its lowest, 112.21 tonnes, in 1750.
That places Singapore 116th out of 220 countries with data for 2022, putting it in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.
