Launched in January 2020, GEM.wiki is a new resource sponsored by Global Energy Monitor and the Center for Media and Democracy. From 2008 to 2019, the two organizations sponsored the CoalSwarm and FrackSwarm portals on SourceWatch. These resources, comprising over 17,000 footnoted pages, have now been combined into a single wiki platform devoted to information on fossil energy, climate, and the clean energy transition.
