The central task of the air quality plan is to assess and to develop measures to reduce the air pollution in order to meet the air quality limit values as quickly as possible everywhere in Berlin.
The action planning has been focusing on reducing nitrogen dioxide pollution, because the limit value for the annual average could not be safely met in 2020 in 117 polluted street sections (around 15 kilometers). Hence, we clearly need to consider further measures.
As our source analysis has shown, around three quarters of the nitrogen dioxide pollution stems from motorized road traffic, i.e. from the combustion engines in cars and trucks. The reduction of pollutant emissions from road traffic has therefore been a priority of the air quality plan.
The planning of measures was carried out in an integrated way taking into account existing thematic plans. This was true especially for road transport, based on Berlin’s new Mobility Act and the emerging planning processes, resulting in an update of the urban development plan for mobility and traffic and the local public transport plan. The urban development plans for centers, for trade and industry and for climate, the Berlin energy and climate protection program and the noise action plan were taken into account as well.
The measures of the second update of the air quality plan can be divided into two groups:
