CARMA--Carbon Monitoring for Action is a global database that compiles the CO2 emissions from more than 50,000 power plants and 4,000 power companies in the world. Power generation accounts for about one-quarter of total emissions of carbon dioxide, the main culprit in global warming.
The on-line database, compiled by the Center for Global Development (CGD), an independent policy and research organization that focuses on how the actions of the rich world shape the lives of poor people in developing countries, lays out exactly where the CO2 emitters are and how much of the greenhouse gas they are casting into the atmosphere. It also shows which companies own the plants.
