Exxon reasserts its methane position as EPA preps rollback

ExxonMobil is reasserting its self-imposed commitment to cut emissions of methane, a potent greenhouse gas that’s the primary component of natural gas, as the Environmental Protection Agency prepares to repeal regulations. Why it matters: The comments, posted Tuesday by the CEO of XTO Energy, an Exxon subsidiary with large U.S. natural-gas operations, illustrate an awkward predicament facing industry under President Trump. Some of the biggest global companies are seeking to emphasize a social license to produce fossil fuels even as the Trump administration pursues aggressive regulatory rollbacks.
