ExxonMobil Corp., the world’s biggest publicly traded oil company, is calling on the Environmental Protection Agency to regulate emissions of methane from all new and existing oil and gas wells across the country, according to a letter obtained by Axios.

The big picture: Methane, a potent greenhouse gas, is the primary component of natural gas and is sometimes purposefully or inadvertently leaked in the production and transport of the fuel, as well as when drilling for oil. The EPA has been slow in its approach toward rolling back Obama-era methane rules, in part due to industry divisions.

Details: Through its subsidiary XTO Energy, Exxon is one of America’s biggest producers of natural gas. It has two reasons to back such a regulation.

  1. Exxon is facing pressure from investors and lawsuits over climate change. By calling for regulations, it’s an attempt to show Exxon wants gas to be as clean as possible, even if those regulations never happen. “We believe the correct mix of policies and reasonable regulations help reduce emissions, further supporting the benefits of natural gas in the energy mix,” writes Gantt Walton, vice president in Exxon’s Washington office, in the letter sent as part of the regulatory process.
  2. As a massive global company, Exxon is positioned to benefit financially over smaller companies. It can easily afford pollution-control equipment that others have a harder time obtaining.

Between the lines: This is a subtle escalation in Exxon’s positioning on this issue. The company has previously said it backs federal methane regulations, but — until now —had not gone as far as to ask the EPA to do so in writing.

  • It’s also significant that Exxon is asking the agency to regulate methane emissions from existing wells, which would affect hundreds of thousands of wells. Under Trump, the EPA is very unlikely to do this. President Obama’s EPA had started the initial groundwork for such a rule, but didn’t get far before Trump took over.

What’s next: This letter is in response to a technical rollback EPA is undertaking. The agency is expected to propose a broader rollback of the rules soon.

The big picture: The Rio 2016 silver medalist's winning time in the men's 400 meters Individual Medley Final was 4 minutes 9.42 seconds. His teammate Jay Litherland took silver, .86 seconds behind him. Moments later, Kieran Smith grabbed a third medal for the U.S. when he won bronze in the 400-meter freestyle.

DOJ won't investigate nursing home deaths in N.Y. and 2 other states

The Department of Justice has decided not to launch a civil rights investigation into whether policies in New York, Pennsylvania and Michigan contributed to pandemic deaths in nursing homes, according to a letter sent to Republicans.

Why it matters: The Trump DOJ requested data from the three states plus New Jersey last August "amid still-unanswered questions about whether some states, especially New York, inadvertently worsened the pandemic death toll by requiring nursing homes to accept residents previously hospitalized for COVID-19," per AP.

Former Blizzard CEO says he "failed” women at the studio

Mike Morhaime, who co-founded and worked at video game studio Blizzard for 28 years, has apologized publicly for toxic work conditions at his former studio, which is now the subject of a discrimination and harassment lawsuit by the state of California.

Why it matters: Morhaime is no longer at Blizzard, but was its leader for most of its existence and therefore was in charge when much of what is alleged in California’s suit would have occurred.
