The FWA is about activities to deliver a range of products of the CAMS portfolio especially relevant for Policy Users. It also includes work in the area of design and implementation of European air quality policies, by supporting directly the European Commission’s Directorate General for the Environment (DG-ENV) and Joint Research Centre (JRC), as well as the European Environment Agency (EEA) and ensuring a close liaison with them. This work will build on all the relevant products and services in the CAMS portfolio in order to bring most relevant information to these stakeholders. It will also interface with the CAMS national collaboration programme, involving all the EU Member States and Copernicus cooperating states, which aims to facilitate further the elaboration and implementation of air quality and emissions policies.
