Air pollution is harmful to human health and the environment. Human activity is a major driver of poor air quality globally, particularly in towns and cities. Introducing measures to improve air quality can therefore deliver many benefits to Scotland's people and our environment.
Following the UK's exit from the European Union, Environmental Standards Scotland (ESS) was set up to monitor public bodies' compliance with their environmental obligations, including those relating to air quality.
On 29 September 2022, ESS published a report in response to the European Court of Justice's (ECJ) judgement that, across the UK, breaches of air quality limit values for nitrogen dioxide had been "systematic and persistent" between 2010 and 2017. The report provided recommendations to the Scottish Government of how they can meet their legal limits on nitrogen dioxide levels, including through changes to their monitoring, governance structures and local air quality management.
