IMPEL is an informal Network of European regulators and authorities concerned with the implementation and enforcement of environmental law. It plays an important role in harmonizing inspection practices in Member States. It is composed of all the countries of the "enlarged" Europe, that is to say 30 countries today.
This network has been functioning since 1992 through thematic working groups ("clusters"), exchanges or review initiatives between countries, and two plenary meetings per year. IMPEL has released several reports, among which reports on inspector training, waste consideration in permitting, or minimum criteria for environmental inspection. This latter document was used as a base for the Recommendation 2001/331 of the European Parliament and of the Council of 4 April 2001 providing for minimum criteria for environmental inspections in the Member States. The following of its effective enforcement is one of IMPEL’s important tasks. IMPEL also reports to the Commission on the concrete stakes in enforcing European obligations on preventing risks and pollutions. As of 31 march 2008, IMPEL has become an international non-profit association with eight founding members including the French ministry of sustainable development.
The European Commission has been supporting IMPEL’s activities since its creation. It co-chairs plenary meetings that are hosted by the country in charge of the Presidency and that manage the whole activities of the network.
The DPPR (Service de l’environnement industriel) represents the French ministry of sustainable development in IMPEL and organises the French participation in the activities of the network, notably by members of the inspectorate of classified installations.
