Thank you for contacting me about air quality.
Air pollution is the biggest single environmental threat to public health and Ministers are continuing to take robust action to improve air quality and minimise public health impacts. Air pollution has reduced significantly since 2010: emissions of nitrogen dioxide have fallen by 44 per cent, sulphur emissions have fallen by 70 per cent and fine particulate matter (PM2.5) emissions have fallen by 18 per cent.
Through the Environment Act 2021, the Government is continuing to improve air quality with a target to have an annual mean concentration target for PM2.5 levels at 10 µg per m3 or below by 2040, as well as a target to reduce population exposure to PM2.5 by 35 per cent by 2040 (compared to 2018). I understand that the Department for Environment, Food and Rural Affairs believes that these levels cannot be achieved by 2030 but can by 2040.
Further, Ministers have placed a duty on local authorities to keep air pollution within legal limits and expect them to take action. The Government provided £883m of dedicated funding to help local authorities develop and implement local nitrogen dioxide air quality plans and support those affected by these plans. In addition, the Air Quality Grant helps councils to develop and implement measures to benefit schools, businesses and communities and reduce the impact of air pollution on people’s health.
Finally, through the Environmental Improvement Plan 2023, the Government will challenge local authorities to improve air quality quicker by assessing their performance and use of existing powers, while supporting them with clear guidance, funding and tools. Ministers will facilitate the rollout of further Clean Air Zones by local councils in areas that are in breach of air quality statutory limits, with further zones and other non-clean air zone measures as required.
Thank you again for taking the time to contact me.
