President Barack Obama unveiled a sweeping plan Tuesday to combat climate change and prepare the U.S. and other nations for its effects. Some highlights of the president's plan:
— Issue a presidential memorandum to launch the first-ever federal regulations on carbon dioxide emissions from existing power plants.
— Finalize proposed limits on carbon dioxide emissions from new power plants without further delay.
— Provide up to $8 billion in federal loan guarantees to spur investment in efficiency projects and advanced fossil energy, including technology to limit carbon emissions.
— Expand permitting for renewable energy projects like wind and solar on public lands, with a goal of powering more than 6 million homes by 2020.
— Set a goal of installing 100 megawatts of renewable energy projects on federally assisted housing projects by 2020.
— Take more aggressive steps to increase efficiency for appliances and federal buildings, with a goal of reducing carbon dioxide pollution by 3 billion metric tons overall by 2030.
