The Chamber’s position on climate change:
The Chamber has in its public documents, Hill letters and testimony, supported efforts to reduce greenhouse gas emissions in the atmosphere. Our position is simple: There should be a comprehensive legislative solution that does not harm the economy, recognizes that the problem is international in scope, and aggressively promotes new technologies and efficiency. Protecting our economy and the environment for future generations are mutually achievable goals.
To that effect the Chamber created an achievable plan...

While they opposed Waxman-Markley and using the Clean Air Act to regulate CO2, they support a comprehensive solution utilizing renewable energy (they also support funding research in this arena).
