Letter to the editor: Big Oil’s endorsement of carbon fee an encouraging reversal It also would be heartening to see Sens. King and Collins and Rep. Golden join Rep. Pingree in supporting the Energy Innovation Act. Share I was surprised but pleased to learn that Big Oil has joined the climate change battle by endorsing a price on carbon dioxide. On March 25, the Associated Press reported in the Press Herald that the American Petroleum Institute, the top lobbying group for oil and gas companies, favors putting a price on CO2 emissions (“In shift, oil industry backs federal price on carbon dioxide emissions”). This is a key strategy in combating climate change, and this support is a reversal of the lobby’s long-standing opposition to such an approach.
