Greenpeace is an independent global campaigning network, founded in Canada in 1971 by a group of environmental activists. Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity", and focuses its campaigning on worldwide issues such as climate change, deforestation, overfishing, commercial whaling, genetic engineering, anti-war, and anti-nuclear issues. It uses direct action, advocacy, research, and ecotage to achieve its goals. The network comprises 26 independent national/regional organisations in over 55 countries across Europe, the Americas, Africa, Asia, Australia and the Pacific, as well as a coordinating body, Greenpeace International, based in Amsterdam, Netherlands.

Greenpeace is known for its nonviolent direct actions and has been described as one of the most visible environmental organizations in the world. It has raised environmental issues to public awareness and knowledge, and influenced both the private and the public sector. The organization has received criticism; it was the subject of an open letter from more than 100 Nobel laureates urging Greenpeace to end its campaign against genetically modified organisms (GMOs).
