"The oil industry's covert campaign to rewrite American car emissions rules," 13 Dec 2018

When the Trump administration laid out a plan this year that would eventually allow cars to emit more pollution, automakers... [said] the changes... went too far... but...there was a hidden beneficiary of the plan that was pushing for the changes... the nation’s oil industry... Marathon Petroleum... worked with powerful oil-industry groups and a conservative policy network... to run a stealth campaign to roll back car emissions standards... The standards that the Trump administration seeks to weaken required automakers to roughly double the fuel economy of new cars, SUVs and pickup trucks by 2025. Instead, the Trump plan would freeze the standards at 2020 levels... increas[ing] greenhouse gas emissions in the United States by more than the amount many midsize countries put out in a year and reverse a major effort by the Obama administration to fight climate change.

Gary R. Heminger, Marathon’s chairman and chief executive, said in a statement that the company supported “sound fuel economy standards” and wanted to “help ensure they are achievable and based on existing technology.” He added, “We appreciate the administration’s willingness to conduct a thorough review in order to ensure future standards are achievable and will actually benefit American consumers.” [also refers to Chevron, ExxonMobil, Facebook, Koch Industries, Phillips 66]
