The island’s air is 40% cleaner than the UK average, according to a new government report.
The Air Quality Monitoring Report 2026, published by DEFA, measured nitrogen dioxide and sulphur dioxide levels at 63 locations between October 2023 and October 2025.
Results show nitrogen dioxide averaged 13 micrograms per cubic metre, compared to the UK average of 21 and the UK action level of 40. Sulphur dioxide averaged just one microgram per cubic metre, well below the UK threshold of 20.
Air quality near schools remained consistently below safety limits throughout the two-year period and while short-term increases were recorded at Braddan Bridge and Peel Road during rush hour, but did not affect overall results.
Minister Clare Barber said: “This report demonstrates that we are not only committed to protecting our environment, but recognise the importance of effective monitoring to ensure our efforts are targeted and effective.
“As a UNESCO Biosphere, we take our responsibility to balance people and nature seriously, and these results show that the Isle of Man continues to offer an exceptionally clean and healthy environment for residents and visitors alike.”
