The World Wide Fund for Nature (WWF) is a Swiss-based international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment.[5] It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States. WWF is the world's largest conservation organization, with over 5 million supporters worldwide, working in more than 100 countries and supporting around 3,000 conservation and environmental projects.[6] It has invested over $1 billion in more than 12,000 conservation initiatives since 1995.[7] WWF is a foundation with 65% of funding from individuals and bequests, 17% from government sources (such as the World Bank, Foreign Office, and USAID) and 8% from corporations in 2020.[8][9] WWF aims to "stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature."[10] Living Planet Report has been published every two years by WWF since 1998; it is based on a Living Planet Index and ecological footprint calculation.[5] In addition, WWF has launched several notable worldwide campaigns, including Earth Hour and the debt-for-nature swap, and its current work is organized around these six areas: food, climate, freshwater, wildlife, forests, and oceans.[5][7] WWF has faced criticism for its corporate ties[11][12][13] and for support of conservation measures that have resulted in violent conflict with local people.[14][15] WWF is part of the Steering Group of the Foundations Platform F20, an international network of foundations and philanthropic organizations.[16]
