* Obama pushing Congress for a cap-and-trade system

* President may not stick with permit auction goal (Adds background on proposal in Congress)

WASHINGTON, April 8 (Reuters) - U.S. President Barack Obama will be flexible about climate change legislation moving through Congress, the White House said on Wednesday, indicating some wiggle room on his demand for full auctioning of carbon emissions permits to industry.

"The president has asked Congress to send him comprehensive energy legislation that would spur a transition to a clean energy economy, create thousands of green jobs, and wean us of our dependence on foreign oil," spokesman Ben LaBolt said.

"Members of Congress are looking at a variety of policy options to help us make that transition, and the administration will be flexible during the policymaking process as long as those larger goals are met."

Obama, a Democrat, is pushing for the creation of a cap-and-trade system to reduce emissions blamed for global warming.

Cap-and-trade systems operate by the government setting a limit on the amount of carbon dioxide or other greenhouse gases that factories and other polluters produce, and allowing them to buy or sell permits with the right to release more.

As a presidential candidate, Obama called for 100 percent of permits to be auctioned, rather than given free of charge, to participants in such a system.
