Greenpeace is a non-governmental environmental organization with offices in over forty countries and with an international coordinating body in Amsterdam, The Netherlands. Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity" and focuses its campaigning on world wide issues such as global warming, deforestation, overfishing, commercial whaling and anti-nuclear issues. Greenpeace uses direct action, lobbying and research to achieve its goals. The global organization does not accept funding from governments, corporations or political parties, relying on more than 2.8 million individual supporters and foundation grants. Greenpeace is a founding member of the INGO Accountability Charter; an international non-governmental organization that intends to foster accountability and transparency of non-governmental organizations.

Greenpeace evolved from the peace movement and anti-nuclear protests in Vancouver, British Columbia, in the early 1970s. On September 15, 1971, the newly founded Don't Make a Wave Committee sent a chartered ship, Phyllis Cormack, renamed Greenpeace for the protest, from Vancouver to oppose United States testing of nuclear devices in Amchitka, Alaska. The Don't Make a Wave Committee subsequently adopted the name Greenpeace.
