FACTBOX: U.S. proposals in Copenhagen to fight climate change

(Reuters) - The United States laid out its position last month for the U.N. climate change talks in Copenhagen, pledging to cut emissions in a range of 17 percent by 2020 compared to 2005 levels, in line with legislation in the U.S. House of Representatives.

President Barack Obama will attend the Copenhagen talks on Friday. Below are the exact figures and other elements of the U.S. proposals:

EMISSIONS CUTS

The United States has pledged to make the following cuts in its greenhouse gas emissions compared to a 2005 base year:

-- an emissions reduction target "in the range of 17 percent" by 2020

-- a 30 percent emissions reduction in 2025

-- a 42 percent emissions reduction in 2030

Compared to 1990, the base year used by the European Union and many other developed countries, the figures correspond to:

-- a 3 percent reduction in 2020

-- an 18 percent reduction in 2025

-- a 32 percent reduction in 2030

IN LINE WITH CONGRESS

The Obama administration's hands have been tied in international negotiations because a domestic climate bill has not yet become law. The House of Representatives has passed its version, but a Senate bill is languishing.

The House passed a bill that sets a 17 percent reduction target for emissions by 2020 from 2005 levels. A Senate version is shooting for a 20 percent cut.

The White House said its 2020 targets would be flexible, based on the outcome of final legislation, but it chose the less ambitious 17 percent figure passed by the House to ensure its negotiating position would have lawmaker support.

White House officials conferred with lawmakers before laying out the U.S. plans.

OTHER PROPOSALS & FINANCING

The United States has made other proposals as part of the Copenhagen talks:

- On Wednesday, it pledged $1 billion as part of a $3.5 billion scheme for initial financing toward slowing deforestation.

- On Monday, it pledged to contribute $85 million to a $350 million multinational fund aimed at speeding up renewable energy and energy efficiency technologies in poor countries.

- The United States has said it will pay its fair share to help poor nations deal with climate change. It will contribute about $1.2 billion this year, but has not made a concrete proposal for the following years.
