Del. Brian J. Moran (D-Alexandria) has purchased "carbon offsets to neutralize the carbon footprint" of the Virginia delegation while at the Democratic National Convention in Denver next week.

A carbon footprint measures the affect human activity has on the environment through greenhouse gases. Moran, who is not a delegate but will be attending the convention, purchased carbon offsets that will be invested in renewable energy through Native Energy.

"Democrats have a long track record as champions of our environment," Moran said. "Leaving a clean and healthy world for the next generation is both a moral obligation and an economic necessity. It's important we show our commitment to this cause with both our words and our actions."

The Virginia delegation will produce approximately 115 tons of carbon-based pollution from air and ground travel, accommodations and waste, according to national Democratic officials.

Delegates have already offset 44 of those tons. Moran's offset includes his own carbon impact.
