WASHINGTON -- House Democrats today are unveiling their climate change legislation, a bill that would seek to cut carbon emissions by 20 percent by 2020 and by 85 percent by 2050.
The bill would also establish a cap-and-trade system to push utilities and industry polluters to meet those goals, according to a document obtained by the Globe.
The bill, which is being introduced by Representatives Henry Waxman of California, chairman of the House Energy and Commerce Committee, and Ed Markey of Massachusetts, chairman of the Energy and Environment subcommittee, would also create a renewable energy standard that requires wind, solar, and other renewable sources to meet 25 percent of US energy needs by 2025. And it would create an energy efficiency resource standard that requires utilities to achieve a savings of 15 percent of electricity and 10 percent of natural gas by 2020.
