Fracking is doable if there's full disclosure of all chemicals used. Secondly science dictates the policy rather than politics. Third there's collaboration between environmental groups and the natural gas industry.

Our work on light bulbs wasn't an arbitrary mandate. We didn't just pick a standard out of the air or look for a catchy sounding standard like 25 by 2025 not based in science or feasibility. Instead we worked with both industry and environmental groups to come up with a standard that made sense and was doable.
