Democratic presidential candidate John Edwards pledged to run a "carbon neutral" campaign that would offset any contributions that it makes to global warming. The former senator often travels in private jets that spew carbon dioxide. He vowed to compensate for that, and for his campaign's other energy consumption, by purchasing "carbon offsets" from a company that supports renewable energy projects. "It's not cheap, but we think we have a responsibility to do it," Edwards said.
