US Senate climate bill cuts carbon emissions-document

WASHINGTON May 11 (Reuters) - A new climate change bill to be unveiled in the U.S. Senate on Wednesday will try to achieve a 17 percent reduction in carbon dioxide emissions by 2020, from 2005 levels, according to a summary of the bill given to senators and obtained by Reuters.

The legislation, which faces a tough battle in the Senate, is being introduced by Democratic Senator John Kerry and independent Senator Joseph Lieberman.

Besides cutting carbon pollution, it contains incentives to expand U.S. nuclear power generation and offshore oil drilling, but requires some protections in the wake of the Gulf of Mexico oil spill.
