CARMA is an organization that monitors carbon produced by power plants around the world. They have an interactive map to visualize what parts of the world are the worst offenders, you can also see which companies are the worst polluters. It’s great to see a site that puts all of this information into one place for activists and researchers to access easily.

The objective of CARMA.org is to equip individuals with the information they need to forge 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.

For several thousand power plants within the U.S., CARMA relies upon data reported to the Environmental Protection Agency by the plant operators themselves as required by the Clean Air Act. CARMA also includes many official emissions reports for plants in Canada, the European Union, and India. For non-reporting plants, CARMA estimates emissions using a statistical model that has been fitted to data for thousands of reporting plants in the U.S., Canada, the EU, and India. The model utilizes detailed data on plant-level engineering and fuel specifications. CARMA reports emissions for the year 2000, the current year, and the future (based on published plans).
