APAT experts participated in the work of Community bodies responsible for promoting and developing EMAS and ECOLABEL voluntary instruments, like the EMAS Committee, the competent national bodies, and the accreditation bodies.  This activity also includes participation in the European Informal IPP Network, an informal network of experts from the member states promoted by the European Commission to support development of the Integrated Product Policy (IPP) strategy.

APAT also participates in the activities of the Committee (established by Decision of the Council 99/296/EC) as called for by the Monitoring Mechanism based on the commitments contained in the Framework Convention on Climate Change (UNFCCC) and in the European Climate Change Programme - ECCP, aimed at coordinating the forces of the member states in meeting obligations deriving from this international environmental protection instrument.

In collaboration with the Ministry of the Environment and Territorial Protection, APAT participates in various projects as part of the IMPEL (Implementation and Enforcement of the Environmental Law) network. This network, established in 1995, handles both technical and legal aspects of environmental legislation. The network’s activities are partially funded by DGXI, and it has its own secretariat with offices in Brussels.

In particular, APAT participated in the IMPEL task force on “best practices concerning training and qualification for inspectors in the EU,” which is intended to draw up guidelines for “Training and qualification for Inspectors”, and in the IMPEL Olive Oil programme, whose coordinator is Spain, and whose objective is to define the best technologies in the olive-oil production cycle. APAT provides national coordination for the European Environmental Network, Green Spider. This network, which deals primarily with topics involving environmental communication, was established in 1995 and is coordinated and funded by the Environment DG. The Board of Directors is currently composed of 8 members: Italy, which held the presidency in 2003, Denmark, Estonia, Ireland, Finland, Bulgaria, Malta and Germany; the EEA and the Environment DG are permanent members and the European Environment Agency hosted the annual meeting in September 2003 in Copenhagen. The next meeting will be held in Rome in September 2004; its organisers will include the Ministry of the Environment and Territorial Protection, APAT, which serves as president, and the Environment DG.  In addition, APAT participates in the Floepje Project for the development of educational materials for school-age children, together with Austria, Belgium, Ireland, Bulgaria, Romania, Hungary, Cyprus, Denmark, Netherlands, Germany and Slovenia, and in communication, information and training exchange activities with other international networks (Greenteachers, Urban Ecology, Eurobarometro, Natura 2000, Environment for Young Europeans Web site, etc.).
