Improving Air Quality- strategies and measures for air quality plans is aiming to be a source of inspiration and smorgasbord of measures that can be included in local air quality plans to improve local air quality. The catalogue’s target audience is local governments from the Western Balkans. Keeping in mind that this region is geographically diverse, local conditions must be taken into account when deciding on whether or not the measures are relevant for a particular locality. The suggested measures have been grouped in the following categories: residential heating, transportation and urban planning, electricity and heat supply, industry and miscellaneous. The study was financed by the Swedish Environmental Protection Agency within the program Partnership for Improving Air Quality in the Western Balkans. It is based upon local documents such as air quality plans and environmental strategies, reports and current research.
