The project includes the implementation of the Programme for the exchange of heat sources in the homes of the Zlín Region II. The aim of the project is to improve air quality in residential development of towns and municipalities of the Zlín Region by long-term reduction of imission concentrations of the most problematic pollutants (suspended particles PM10, PM2,5 and benzo(a)pyrene). Reduction of imission concentrations will be achieved by limiting emissions of pollutants from local heating of households through the exchange of unsuitable, obsolete heat sources to solid fuels.
