The House legislation calls for:
Reducing greenhouse gases by 17 percent by 2020 and 83 percent by 2050 by allowing pollution permits to be bought and sold.
Limiting emissions from major industrial sources, including power plants, factories and refineries. Agricultural emissions would be exempted.
Controlling carbon dioxide from the burning of fossil fuels and limiting six other greenhouse gases.
Allowing companies to meet emission-limiting targets by investing in offset projects such as tree planting and forest protection.
Requiring electric utilities to produce at least 12 percent of their power from renewable sources by 2020 and save up to 8 percent in energy efficiency.
Imposing tighter standards on new coal-fired power plants and providing $1 billion a year to capture carbon dioxide from such plants.
Establishing standards requiring new buildings to be 30 percent more energy-efficient by 2012 and 50 percent more efficient by 2016.
Protecting consumers from rising energy costs by giving rebates and credits to low-income households.
