A mayoral hopeful wants to use his social enterprise background to get Winnipeggers thinking about — and acting on — climate change. "This city hall thinks that our carbon emissions are a problem, and we have to spend money to address the problem. Its not a problem. It's our biggest economic opportunity we've had available to us in a generation," Shaun Loney said. Loney, who's helped create five different social enterprise businesses, wants to introduce "smart taxes" if he were mayor. Essentially, they're taxes or policies that reward businesses who focus on things like cutting carbon emissions or reducing the amount of water runoff in the city's sewer system, which eventually runs into Lake Winnipeg.
