ANNAPOLIS, Md. (7News) — The Maryland Public Service Commission ruled on Thursday that Washington Gas Light (WGL) misled its customers.

The complaint was first filed in 2021, when the Maryland Office of People’s Counsel accused the utility company of including misleading information about natural gas in advertising distributed in October and November of that year.

Later, the Sierra Club Maryland Chapter, represented by Earthjustice, joined the lawsuit.

The piece of advertisement in question claimed that gas was “clean energy” with no environmental impacts. It also claimed that using gas was one-third the price of electricity – and that choosing gas instead of electricity would save “acres of trees.”

“Yesterday’s ruling is a win for both customers and the environment,” said Josh Tulkin, Director of the Sierra Club Maryland Chapter. “It protects Washington Gas Light customers from receiving misleading information in their utility bills. Unlike what was stated in the bills, gas has negative environmental impacts both on our indoor air quality and on our climate. We applaud the Maryland Public Service Commission for ruling in favor of accurate information for customers.”
