At an Energy Information Administration conference today, Department of Energy Secretary Steven Chu said that the Department will play a vital role in developing cap-and-trade policy. He noted that the DOE will provide key data and research in the development of low carbon technologies, as well as energy efficient technologies for buildings and vehicles. With respect to the strong emission targets in the recently released Waxman-Markey discussion draft of cap-and-trade climate change legislation, Chu remarked, “As we learn more about the climate and prospective dangers, we are getting increasingly uneasy that the carbon levels, as they go above 500, 550 parts per million, could trigger some tipping points that we are very concerned about.”
