The main goal of the project proposal "For cleaner air in the municipality of Kardzhali" is to improve the quality of atmospheric air in the municipality of Kardzhali, which is one of the municipalities with impaired air quality according to this indicator in the period 2017-2021. The specific objectives of the project proposal are aimed at reducing emissions of primary GHG10 from domestic heating with solid fuel through the supply and installation of environmentally friendly heating appliances/systems. As well as to encourage the reduction of electricity consumption from the grid among the target group and to increase the share of renewable energy used. The target group of the project is the citizens and legal entities owning a residential property in the territory of the municipality of Kardzhali and using solid fuel heating devices - wood and coal. The main activities of the project are related to the replacement of solid fuel heating devices with ecological alternatives. In order to ensure wide awareness among the target group, a communication campaign and a campaign to collect applications will be organized and conducted. As a result of the implementation of the project, the emissions of dust particles from domestic heating will be reduced, which in turn will lead to an improvement in the quality of atmospheric air in the municipality of Kardzhali.
