Between the new rule and a related set of 2012 regulations, EPA has suggested that we are currently on course for a 20 to 30 percent cut in methane emissions by 2025. However, the Obama administration has promised a 40 to 45 percent cut by that year, meaning more action is needed.
Thursday’s regulations only cover new and modified wells, and Environmental Defense Fund research suggests that by 2018, nearly 90 percent of methane emissions from the oil and gas sector will come from sources that existed before 2012.
As for these sources, EPA has issued a request that will “require oil and natural gas companies to provide extensive information needed to develop regulations” targeting emissions from existing infrastructure. Those regulations, however, likely won’t begin development until the next administration cozies up in the White House. (And depending on the administration, may never be developed at all!)
In the grand scheme of U.S. emissions, methane makes up about 11 percent of our greenhouse gases, and about one-third of that figure is from oil and gas. This is where the existing infrastructure starts to feel a little more pressing: If we take the EDF’s projection at face value, that means that the new rule will only address the sources of less than 1 percent of all U.S. greenhouse gas emissions.
Ignoring other greenhouse gases, even the methane front alone looks a little dismal. The United States has around 3 million abandoned wells, many of which are probably leaking the gas. The natural gas sector already loses about 1 to 3 percent of its product (which is mostly methane) due to leakage.
