In November 2007 CGD’s Carbon Monitoring for Action (CARMA) provided the first global database on CO2 emissions from the world’s 50,000 power plants and the firms that own them. CARMA was widely welcomed as a tool for public education and as an important first step toward reliable, consistent information on plant-level emissions that will be crucial for future international agreements to cut greenhouse gas emissions. In this new working paper, CGD senior fellow David Wheeler and co-author Kevin Ummel describe CARMA’s methodology, assess its strengths and weaknesses, and test its accuracy across countries and at different geographical scales. They also invite power companies that have verified emissions data to submit them for inclusion in CARMA.
