Public buses contribute a large part to the overall pollution within urban areas. The “Clean Buses” project chooses another approach towards cleaner air: retrofitting existing buses with diesel particulate filters. This reduces the PM emissions by more than 95%. The project focuses on Germany, Poland and the Czech Republic, especially on the main capitals Warsaw and Prague. In Germany many steps have already been taken, but there is still a lot of potential for improvement. Besides diesel particulate emissions the reduction of Nitrogen Dioxide (NOx) from buses is also an important project aim.

Another important aspect of the project is increasing awareness for the issue of “air pollution”. Especially the society, administrative representatives, politicians and public transport companies are supposed to gain an understanding of the causal context between technical installations and clean air. In order to reach these goals the VCD works closely together with Polish and Czech NGOs.

In each country several round tables took place, e.g. in Berlin, Warsaw, Prague or Cracow. Representatives from bus companies, municipalities, national ministries and NGO´s have come together to discuss technical and financial aspects of bus retrofitting. Other instruments of improving urban air quality such as cycling or the introduction of Low Emission Zones (LEZ) has also been discussed. In September 2014, the Clean Air project has organized a conference in Berlin. Representatives from Polish and Czech municipalities, ministries, NGO´s and journalists have been invited to discuss local and national measures for reducing air pollution with German experts.  The results of the round tables have been collected in three national guidelines.

Key result of the project is the Guideline 'Saubere Busse':
