Carbon Monitoring for Action (CARMA) was a global database that gathered and presented the best available estimates of CO2 emissions for 50,000 power plants around the world and the identities of the 4,000 firms that own them. Electricity production is responsible for about one-quarter of all climate-warming greenhouse gas pollution, and CARMA was the only global database for tracking specific sources of CO2, the most important greenhouse gas. First launched in 2007, CARMA was expanded and upgraded in 2012 to incorporate data from authorities in the United States, European Union, Canada, India, and South Africa as well as the International Atomic Energy Agency. For facilities lacking publicly-disclosed data, estimates were generated using a new suite of statistical models.
The objective of CARMA was to provide information necessary to create a cleaner, low-carbon future. By providing complete information for both clean and dirty power producers, CARMA hopes to influence the opinions and decisions of consumers, investors, shareholders, managers, workers, activists, and policymakers. CARMA builds on experience with public information disclosure techniques that have proven successful in reducing traditional pollutants.
CARMA is no longer active and the last update was November 28, 2012. The database, including documentation, is available for download here.
Nearly two years after the U.S. Supreme Court ordered the Environmental Protection Agency (EPA) to determine whether greenhouse gases (GHGs) pose a threat to peoples’ health or welfare – the first step toward regulation -- the EPA this week issued a draft rule on a national GHG registry:
