Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the creation of a new index that will measure carbon dioxide emissions from the U.S. electrical power generation sector. The Carnegie Mellon Power Sector Carbon Index will track the environmental performance of U.S. power producers and compare current emissions to historical data collected nationwide for more than two decades. A quarterly press release will inform interested parties of power sector carbon emissions performance trends. In addition, CMU will provide an online resource for a wide variety of power sector emissions data and forecasts.
