The most recent figure for emissions of air pollutants in Seychelles is 17,214 tonnes, measured in 2022. That is the highest value across all 273 years on record.
Compared with earlier readings it is up 10.3% on the previous year and up 61.9% over ten years.
Over the whole period, emissions of air pollutants in Seychelles peaked at 17,214 tonnes in 2022 and was at its lowest, 0.83 tonnes, in 1750.

About this data
Nitrogen oxides (NOₓ) are gases that are mainly formed during the burning of fossil fuels. Exposure to NOₓ gases can have negative impacts on respiratory health. NOₓ gases can also lead to the formation of ozone – another air pollutant.
