CARMA's interactive maps and database includes more than 50,000 power plants of different sizes, 4,000 power companies, and nearly 200,000 geographic regions in every country on Earth. Users can view carbon emissions data for the year 2000, the present, and future plans. And all of CARMA’s data is updated quarterly to reflect changes in plant ownership and planned construction. The maps and database show each power facility in a region and gives the plant its own page that reveals the its location, ownership, power production, and CO2 emissions. Users can select individual plants from interactive maps or lists, search for specific plants, or filter and sort the data in multiple ways. The data also show which type of fuel or primary energy input the power facility utilizes to generate electricity.
