Officials say President Obama will put forward a plan to reduce greenhouse gas emissions in the United States in the range of 17 percent below 2005 levels by 2020 during the Copenhagen Climate Talks in December.

They say this reflects Mr. Obama's broader commitment to reduce emissions by 83 percent by 2050 in interim steps as follows:

• 30 percent below 2005 levels in 2025
• 42 percent below 2005 levels in 2030

These numbers are similar to the bills pending in both House and Senate.

White House climate change adviser Carol Browner says the Congressional Budget Office has scored the economic impact of these reductions at $173 a year per family of four in 2020.
