Under the plan, which was developed by a Task Force convened by Mayor Daley in 2007 and co-chaired by Adele Simmons, President of Global Philanthropy Partnership, and Sadhu Johnston, the City’s Chief Environmental Officer, the City will work to reduce greenhouse gas emissions to 25 percent below 1990 levels (1990 levels are the recommended baseline according to the Kyoto Protocol). Other cities have set similar goals, but Chicago claims it’s plan is the first to both identify emission sources and anticipated impacts, and propose ideas that specifically respond to that research.
