WASHINGTON – With the introduction Thursday of broad legislation to curb global warming, a key committee is hoping to move the bill for Senate consideration by the end of the year.

“Today will be remembered as the turning point in the fight against global warming,” Sen. Barbara Boxer, D-Calif., said on the Senate floor, hailing the introduction of the compromise bill sponsored by Sens. John Warner, R-Va., and Joseph Lieberman, a Connecticut independent.

In addition to Warner and Lieberman, there were six other co-sponsors: Republicans Elizabeth Dole of North Carolina, Norm Coleman of Minnesota and Susan Collins of Maine, and Democrats Tom Harkin of Iowa, Benjamin Cardin of Maryland and Amy Klobuchar of Minnesota.

Boxer made combating global warming her top priority after she became chair of the Senate Environment and Public Works Committee in January. She said, however, that she would wait until she had enough bipartisan support before trying to move any legislation through her committee.

Boxer said she will use the Lieberman-Warner bill as the template for committee action, even though it isn’t her “gold standard” – California’s groundbreaking effort to reduce emissions by 80 percent before 2050.

The Lieberman-Warner bill could slash emissions by 60 percent. While it would establish a national program under which carbon emission credits could be bought and sold among industries trying to meet the standard, it initially would assign most of the credits to companies based on their past pollution history.

“We are not among those gushing about this bill,” said Frank O’Donnell, president of Clear Air Watch, an environmental group. “This is a political concession to coal-burning companies.”

Other environmental groups, while emphasizing the need to strengthen the bill, were more complimentary of the progress the Lieberman-Warner bill represented.

Oklahoma Sen. James Inhofe, the senior Republican on the committee and a global warming skeptic, sought to slow down the bill. He asked for multiple hearings on the legislation, saying the annual costs of the bill are likely to exceed $3,500 per family of four.

“This is 10 times the largest tax increase over the last three decades,” he said.

But Lieberman, chair of the committee’s global warming subcommittee, said there would be a single hearing next week and that his panel would then begin to add the finishing touches to prepare the measure for full committee action in November.
