Protect Illinois from Methane Leaks

Methane Potency

The main component of natural gas—methane—is a potent greenhouse gas that is already causing 25% of the global warming we're experiencing today. The natural gas distribution system in Chicago is among the oldest in the country, with lots of pipes wasting gas by needlessly leaking vast amounts of methane.

New laws in 2013 paved the way for replacing leaky pipes in Illinois, but a recent audit of the Peoples Gas pipe replacement project shows there's much more to be done.

Studies show that a small number of leaks are responsible for an inordinately high share of lost gas. Today, new technologies allow utilities to find and prioritize for repair the biggest leaks. It is imperative that Illinois utilities use the best available methods to stop these leaks. That means fixing those that present a safety threat immediately, and prioritizing the rest so that the leaks with the greatest emissions are fixed first.

Take action today: Tell the Illinois Commerce Commission to make sure utilities use state-of-the-art methods to improve their leak reduction programs, and that they report the amount methane they’re saving as a result.

Improve utility efforts to fix the biggest leaks first after addressing leaks that pose a safety risk.
