Environmental Protection Agency officials will hear public comments in Pittsburgh tomorrow on the agency’s proposal to limit carbon dioxide emissions, mostly coming from coal-fired power plants.

But PennFuture wants another greenhouse gas to share the limelight, officials from the environmental advocacy group told PublicSource today. That greenhouse gas is methane.

“Methane leakage is affecting climate change and public health, [which means] more smog and more unhealthy air days,” said Andrew Sharp, the group’s director of outreach.

The EPA’s proposed Clean Power Plan, which will be discussed at the meeting, likely means there’s going to be less coal burned, which could mean relying more on natural gas for the nation’s energy needs, Sharp said.

Three folks from PennFuture stopped by for one of our Newsroom Notable sessions, where PublicSource invites area stakeholders to share what their groups are doing and the challenges they face.

Methane, the primary component of natural gas, is a short-lived but powerful greenhouse gas that is much more potent than carbon dioxide (C02). Methane makes up about nine percent of the nation’s greenhouse gas emissions.

People don’t really “get” the methane issue as much as they do the carbon issue, said Elaine Labalme, the group’s communication’s director.

Methane can leak from oil and gas operations, livestock and landfills, among other sources. With natural gas, it can leak from well pads, pipelines or from gas stoves, Sharp said.

The science is still out on methane leaks. Scientists are trying to figure out how much methane is released into the atmosphere and where it comes from. There are several studies by major universities in the works looking at the issue.

The White House announced several initiatives this week officials say will help reduce methane emissions from natural gas operations.

“Our concern is that with more gas and more people getting their electricity from gas, we really need to get the methane leakage issue under control,” Sharp told PublicSource.

We can reduce carbon dioxide emissions by pivoting from using coal to using more natural gas, said Christina Simeone, the director of PennFuture’s Energy Center. But if we don’t address the issue of methane leakage, we could end up just replacing one greenhouse gas with another.

And if regulators don’t track methane emissions correctly and account for it in air-quality reports, “it’s like you’re an accountant and there’s just stuff that’s off the books,” Simeone said.

While other states, including Colorado, Utah and Wyoming, are doing things to better track methane leaks, Pennsylvania is falling short, Sharp said.

“We really need to figure this out,” Sharp said.

To better track methane leaks in Pennsylvania, regulators could increase inspections of gas well sites and require drillers to install leak detection and repair equipment.

“There are cost effective [and] relatively easy-to-implement solutions available,” he said.

Capturing methane at gas operations in Pennsylvania would help the gas industry because companies could capture and sell more product, Sharp said.

When we ask questions about policymakers’ decisions, like how Allegheny County is handling COVID-19 safety for its employees, things change. When we push for transparency on issues that affect the public, like in the use of facial recognition software by Pittsburgh police, things change.

It takes a lot of time, skill and resources to produce journalism like this. Our stories are always made available for free so that they can benefit the most people, regardless of ability to pay.
