"I am proud that I was the first presidential candidate to call for an 80 percent reduction of greenhouse-gas emissions by 2050," John Edwards tells Grist in an interview on energy and the environment. Dennis Kucinich calls on Americans to "see the connection between global warring and global warming." Chris Dodd touts his plan for a corporate carbon tax. And Bill Richardson explains why he calls himself the "energy president." These conversations are all part of an ongoing series of interviews with presidential candidates conducted by Grist and Outside. More interviews are coming soon, with Democrats and Republicans alike.
