The Stop Esso campaign was a campaign by Greenpeace, Friends of the Earth and People and Planet aimed at boycotting the oil company ExxonMobil (which owns and operates the brand Esso), on the grounds that it is damaging the environment. The campaign alleges that Esso / ExxonMobil is: * not investing in renewable energy sources * denying the existence of global warming * funding the creation of junk science which denies climate change, delaying urgently needed climate change action * undermining the Kyoto Protocol.
