The guidance report was produced by JRC-ERLAP and the EEA European Topic Centre on Air Quality (ETC-AQ), with support from the European Topic Centre on Air Emissions (ETC-AEM). Joint project leaders were Roel van Aalst (ETC-AQ) and Emile de Saeger (JRC-ERLAP).

The task was supervised by Lynne Edwards (DGXI) and Gordon McInnes (EEA). The contact person in the European Commission was Pierre Hecq. Dick van den Hout, consultant for the Commission in air quality matters, has been involved in the work. A meeting with experts from some Member States provided valuable input. We also thank national representatives and other participants in the Steering Group meeting of National Experts on Air Quality and its Working Groups for useful comments and contributions.
