The SCAC-2 program was funded by the Swedish Environmental Protection Agency (Swedish EPA) in order to provide an extended scientific knowledge base in national and international discussions and negotiations on the development of new air pollution policies and measures.

The program was focused on four main areas: air pollution and climate interactions and hemispheric transport, air pollution and human health with focus on particles from transport and domestic wood burning; ecosystem effects (and air pollution – climate interactions) of ozone and nitrogen, the latter with emphasis on national nitrogen budgets and biodiversity. Integrated assessment modelling and identification of the most efficient abatement strategies was also included.

The report contains a detailed summary in Swedish. (In Swedish: Rapporten innehåller en utförlig sammanfattning på svenska.)
