There’s a whole industry dedicated to efficiently detecting methane gas leaks using cutting-edge technology — and as these tools get more sophisticated, methane mitigation becomes more cost-effective by the day. But will the finished rule take full advantage of these resources and hold all producers to the same standard?

As DEP gathers public comment on a proposed rulemaking to cut methane emissions from Pennsylvania’s natural gas industry, new data from the Environmental Defense Fund (EDF) paints a stark picture of what’s at stake: current emissions up to fifteen times higher than official estimates, and projected emissions of up to 14 million tons a year by 2030. EDF researcher Hillary Hull explains.

Nobody knows exactly how much methane is released each year by Pennsylvania's oil and gas industry. But a new Environmental Defense Fund analysis suggests actual emissions could be as high as five times the state's official estimate.

Pennsylvania veterans are joining the call for responsible controls on methane emissions in the natural gas industry.

In 2014, Colorado became the first state to regulate methane emissions from the oil and gas industry. As Pennsylvania takes similar steps, what can we learn from Colorado's experience convening diverse stakeholders to create effective and feasible rules?

More and more states are adopting measures to limit emissions of methane from the production and distribution of natural gas. Finding and fixing methane leaks is good for the environment, but it’s also good for business — like the 20+ companies that are now employing Pennsylvanians to help gas companies boost their own bottom lines by improving efficiency.
