We investigate, expose and confront environmental abuse by governments and corporations around the world.


Our investigations are a fundamental part of our campaigns. We expose those responsible for environmental crimes. We have a global reach, we have research teams and millions of supporters in countries around the world. This means we can investigate environmental crimes and impacts wherever they are happening, whether it is the middle of the jungle, or even, with the help of Rainbow Warrior and its sister ships, in the far oceans.


Do you want to change the world? Do you know about a crime against the planet? Do you want to blow the whistle about it? Do you have inside documents or data which could help us defend the natural world and promote peace by exposing abuse of the environment? Do you have a tip-off or any secret information that could help us fight climate change and fracking, save the arctic, protect the forests and the oceans, or work for peace and disarmament?

We guarantee that if you are a whistleblower:

  1. We will take your call/contact seriously.
  2. We will not deliberately or accidentally reveal your identity without your consent, even if legal action is taken against us.

You can contact us by emailing, calling 0207 865 8100 and asking for the Investigations Unit, or by sending a note to Investigations Unit, Greenpeace, Canonbury Villas, London N1 2PN.
