FACTBOX: White House lays out Copenhagen emissions proposal

(Reuters) - The White House laid out the U.S. negotiating position on Wednesday for U.N. climate change talks in Copenhagen, pledging to cut emissions roughly 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 December 9, officials said.

Below are the proposed figures and other elements of the U.S. proposals:

EMISSIONS CUTS

The United States will pledge 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 still 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.

CALLING ON CHINA, OTHER COUNTRIES

White House officials said the U.S. proposal would come "in the context of an overall deal in Copenhagen that includes robust mitigation contributions from China and the other emerging economies."

But the U.S. proposals are far lower than what the 27-nation European Union has called for. The EU is pledging a 20 percent emissions cut by 2020 compared to 1990 levels and has promised to change that to 30 percent if other rich nations follow suit.

-- Commerce Secretary Gary Locke

-- Energy Secretary Steven Chu

-- Agriculture Secretary Tom Vilsack
