The project addresses the reduction of air pollution levels in the Olomouc Region by limiting the primary emissions of pollutants from local heating of households – family houses (limiting emissions of pollutants (or their precursors), which have been found to exceed the emission limits and to stabilise the emissions of those pollutants that do not exceed the emission limits. Emission reductions will be achieved by replacing heating sources (boilers) to solid fuels in family houses in the region.
