CARMA (Carbon Monitoring For Action) have been mapping the highest emissions of CO2 by power plants over the world. It's mainly a massive database that reveals the carbon emissions of more than 50,000 power plants and 4,000 power companies in every country on Earth. Power generation accounts for 40% of all carbon emissions in the United States and about one-quarter of global emissions.
CARMA would be the first global inventory of a major, emissions-producing sector of the economy. Their objective is to equip individuals with the information they need to forge a cleaner, low-carbon future.
Their website is very well done and you can find what you are searching for easily, like zooming in and get the information for any one of these plants, make an easy search, etc. - hopefully, the blog will be updated soon. Good information is key, and projects like that gives us the tools to help design a better future.
*CARMA is produced and financed by the Confronting Climate Change Initiative at the Center for Global Development, an independent and non-partisan think tank located in Washington, DC.
