He didn't do it quietly, either. Bloomberg chartered a boat to take about 100 Sierra Club activists, friends, TV cameras and reporters out onto the Potomac River for a press conference in front of an Alexandria, Va., coal plant that environmentalist have been try shut, so far without success. Fittingly, he came to D.C. on a day when the heat was sweltering and authorities declared a "Code Orange," an alert meaning that the air is too dirty for kids to play outside.
"The burning of coal does terrible harm to mothers, children and families across the country," Bloomberg declared, calling coal a "self-inflicted public health risk."
Bloomberg and Mike Brune, the Sierra Club's executive director, set an ambitious goal for the group's "Beyond Coal" campaign: They want to shut down about one-third of the nation's coal plants and replace them with clean energy as quickly as possible.
"If we succeed, and I believe we will," Bloomberg said, "we will save millions of lives and we will help millions of children avoid asthma and its debilitating effects."
For those who care about climate change, air pollution and public health, this is the best news out of Washington, D.C., in some time. It comes in stark contrast to the goings-on on Capitol Hill, where House Republicans are doing everything they can to tame the EPA.
Shutting down 30% of America's coal-burning capacity with be hard, but the anti-coal campaigners have some winds at their back. Natural gas prices are low, and the EPA wants to require older coal plants to put on expensive, pollution control technology, over industry objections. And about 10% of the aging fleet of coal plants is already scheduled to close.
Meanwhile, construction of new coal plants have all but come to halt, in part because of opposition from groups like the Sierra Club, which claims to have blocked more than 150 of them.
Brune, who came to Sierra Club after a successful run as leader of the hard-hitting Rainforest Action Network, said the $50 million, spread over the next four years, will enable the club to expand its Beyond Coal campaign from 15 to 46 states and double the number of people working full-time against coal plants, from 100 to 200. The Sierra Club, which is America's oldest and largest grass-roots environmental group, has an annual budget of about $80 million and about 1.4 million members.
Mike (Brune) told me that the club has been talking with Bloomberg since 2007 when his predecessor, Carl Pope, met the mayor during international climate talks in Bali. It's significant that Bloomberg–who made his fortune in the media and is business-savvy–chose to make the donation to the Sierra Club, as opposed to more mainstream or business-friendly groups like the Environmental Defense Fund.
"He likes to take on big fights," Mike said. "He took on tobacco. He took on guns."
Banning smoking in New York City's bars and restaurants was controversial, he recalled, but protecting people from second-hand smoke turned out to be popular.
