Around 90% of citizens in urban areas are exposed to air pollution up to levels considered harmful by the WHO and more than 130 European cities face air pollution above standards set by EU air quality legislation. Participants of the workshop 'Cities in transition - improving urban air quality' will learn more about air quality across Europe with the publication of the European Environment Agency report on ‘Air quality in Europe - 2017’ and discuss options cities have to improve air quality management, in combination with effective implementation of existing legislation on emissions from the industrial, energy, transport and agricultural sectors. Organised by the European Commission and the European Committee of the Regions on 11 October, 14.30-17.00. Register until 29 September (workshop code: 11B111).
