LANSING — Some environmental advocates are frustrated with what they say is a broken promise by the state’s governor to address carbon emissions from Michigan’s coal plants. In response to the EPA’s proposed Clean Power Plan regulations on carbon emissions, Gov. Rick Snyder promised greater use of more environmentally friendly power sources, said Dorothea Thomas, environmental and climate justice organizer for Michigan United, an advocacy group. The EPA proposed regulations were recently put on hold by the U.S. Supreme Court, said Judy Palnau, a communications officer for the Michigan Agency for Energy. As a result, the state has delayed plans for implementing them. “The court stay does introduce a substantial amount of legal uncertainty, so it was deemed wise to hold back,” she said.
