The Environmental Protection Agencies Network (EPAN) is an informal grouping, set up in 2003, to bring together the heads of environment protection agencies and similar bodies across Europe. The Network exchanges views and experiences on issues of common interest to organisations involved in the practical day to day implementation of environmental policy, assessing the state of the environment and communication of environmental issues.

The EPA Network arranges its work on specific topics through various interest groups. The tasks of an interest group range from a simple forum for exchanging good practice examples and sharing experiences, to a group trying to promote specific issues and engaging with policymakers. Through their work, interest groups consider emerging issues and discuss national approaches that help to raise awareness. Interest groups also report on their activities to the plenary meetings and any outputs from the groups are discussed and approved.

The Network works closely with the European Commission as well as with other networks with complementary roles such as the European Union Network for the Implementation and Enforcement of Environmental Law (IMPEL) and European Network of Heads of Nature Conservation Agencies (ENCA).

The Environment and Resources Authority is a member of the EPAN and participates in formal plenary meetings, as well as Interest Groups such as IG Noise Abatement, IG Better Regulation and IG Citizen Science.
