"Chevron chief lashes out at European oil groups on climate change", 3 Jun 2015

The head of Chevron, one of the largest US oil companies, has attacked his European counterparts for backing a global carbon pricing system that he says consumers will never back.  Laying bare the rift between US and European fossil fuel producers over how to deal with rising pressure to tackle climate change, John Watson, chief executive, said that putting a price on carbon emissions was unworkable...Mr Watson said that he understood concerns about climate change and Chevron had taken many steps to address them.  “I am not aware of a company that has done more to address greenhouse gas emissions than my company,” he said.
