OAKLAND, Calif. — A new analysis published by Greenpeace found the House of Representatives' version of the economic stimulus bill would be more climate-friendly than the version passed on Tuesday by the Senate.

The nonprofit hired consulting firm ICF Interational to perform a side-by-side comparison of the energy efficiency and conservation provisions of the competing bills, following a closer examination of the House version that was released last week.

The comparison revealed that the House economic stimulus will reduce U.S. greenhouse gas emissions by about 59 million metric tons, roughly 12 million metric tons more annually than the 47 million metric tons cut by the Senate version. The House version will also save taxpayers and the government nearly $9 billion in utility bills every year -- approximately $3.7 billion more than the $5 billion in savings produced through the Senate package.

The House and Senate must now reconcile the two versions of the package, a final version of which President Barack Obama wants by next week. The House passed its $819 billion version two weeks ago.

Greenpeace argues the economic stimulus package must address climate change because of the hefty price tag that will arise from inaction.

"At a time when Congress must make every dollar it spends count, this analysis shows that the biggest bang for the taxpayer's buck is in energy efficiency and conservation," Kert Davies, Greenpeace USA research director, said in a statement.

An analysis by Moody's found the House version would create about 625,000 more jobs than the Senate economic stimulus bill because the Senate version scales down the amount of aid for states and local governments in favor of larger tax cuts. Less money for states and governments, which are dealing with budget shortfalls, will lead to layoffs of public workers, Bloomberg reported.
