Oil and gas wells let loose a lot of methane, a potent greenhouse gas. In April, when the U.S. Environmental Protection Agency suspended for three months an Obama administration rule to restrict such emissions, it did not defend wells or deny climate change. Instead the agency said the rule had not been studied enough. For instance, the EPA said the costs to get new well-venting systems approved had not been analyzed, so oil and gas companies had been unable to provide input as required by law. https://www.scientificamerican.com/article/make-america-wait-again-trump-tries-to-delay-regulations-out-of-existence/?utm_content=buffer79ca4&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer
