WWF Greece was founded in 1990, as part of the international WWF family, which consists of 29 National Organizations. WWF Greece is registered as a Public Welfare Foundation, according to the provisions of Law 2039/1939 and legally established as such through a Presidential Decree published in the Government Gazette, volume B', issue 22 of 18-1-1994.

WWF Greece’s mission is to conserve the rich biodiversity of Greece, to prevent and eventually to reverse environmental degradation, seeking the harmonious coexistence of humans with nature. Capacity building and awareness raising on crucial and not-readily-comprehensible environmental issues, such as environmental legislation, are amongst WWF Greece’s fields of expertise.

WWF Greece's mission is achieved through its conservation programme, which is structured along five main fields of action are: Fieldwork, Policy, Civil society engagement, Business engagement and Scientific support & documentation.

Since its inception, the organisation has designed and implemented over 80 projects for the conservation of the freshwater, marine and forest ecosystems of Greece, ranging from field research and monitoring of species and habitats, to environmental education and capacity building. WWF Greece has also carried out considerable policy work that has contributed to the improvement of Greek environmental legislation and the attitude of policy-makers and the public towards the environment.
