LOS ANGELES (CBS/AP) — The Sierra Club is suing the California Coastal Commission in an effort to halt approval of U2 guitarist The Edge’s plans to build five mansions on a Malibu ridge.

The Los Angeles Times reports the action filed Thursday in Los Angeles Superior Court says the commission didn’t properly evaluate the project before granting approval last month.

Among other things, the Sierra Club maintains the commission didn’t consider the impact that putting homes in Malibu’s pristine Sweetwater Mesa area would have on air quality and greenhouse gas emissions.

Edge has been attempting to get the project approved since 2011. The plans the commission OK’d last month were a scaled-down version of his original proposal.
