SEPA regulates and monitors certain industrial activities in
Scotland that can generate local airborne pollution. Our work
involves working with and directing local authorities and other
partners to manage and improve air quality. We also provide policy
and operational advice to government, industry and the public on
pollution control and other environmental issues.
In addition, we work towards Scottish and UK objectives and
targets set to address global climate change and the cross-border
transfer of pollutants.
