This is an issue which is largely devolved to the Scottish Parliament. The SNP Scottish Government has been taking concerted action to tackle air pollution.
The Scottish Government has recently launched Cleaner Air for Scotland, our first distinct air quality strategy. It sets out actions across government portfolios that will further reduce air pollution, with a particular emphasis on protecting human health and reducing health inequalities. There are currently 32 Air Quality Management Areas in place across Scotland, the vast majority declared on the basis of transport emissions.
These pollutants, which include fine particulate matter and nitrogen oxides, are largely invisible but no less significant in terms of their impact. Successfully addressing air pollution requires a partnership approach, involving the Scottish Government, its agencies, local authorities, business and industry, professional institutions, non-governmental organisations, and the general public.
Whilst there is still a long way to go, the Scottish Government is taking concerted action to improve air quality.
