Esso has done more than any other company to stop the world from tackling climate change.

For over a decade, it has tried to sabotage international climate change negotiations and block agreements that would lead to greenhouse gas emissions reductions.

Esso also funds groups to produce junk science that denies climate change and supports the climate sceptics, delaying the action that's so urgently needed on climate change.

Esso is also a member of Arctic Power, the lobby group trying to open the Arctic National Wildlife Refuge to drilling.

Greenpeace UK's climate change campaign now focuses on "decentralising" the UK's energy system but campaigns to Stop Esso's parent company, ExxonMobil, are still very much alive and well in the US.
