In his first 100 days in office as governor, he proposed expansion of the beverage container deposit law (bottle bill), a switch by state government agencies to the use of environmentally friendly cleansers, and clean up of the state's "Filthy Five" power plants. He appointed a prominent environmentalist, Douglas Foy, to oversee energy development, transportation, housing, and environmental affairs. Foy helped develop an energy and environment plan that included 72 public and private initiatives, with a goal of deriving 15 percent of the state's electricity from renewable sources such as wind, solar, and nonpolluting fuel cells by 2020, and of reducing greenhouse gas emissions of state agencies by 25 percent. The plan also proposed to impose strict emissions standards on older power plants and sought to substantially reduce soot emissions from diesel buses, trucks, and heavy construction equipment.
