WASHINGTON - President Barack Obama pushed urgently Thursday for passage of legislation to confront global warming, billing it as a job-creating machine rather than the costly "job killer" Republicans denounced and telephoning wavering Democrats on the eve of what could be a historic House vote.
Speaking in the Rose Garden at the White House, Obama said Washington must not miss the opportunity to work on cleaning the air, creating new "green" energy jobs and moving the nation away from its reliance on fossil fuels such as oil, coal and natural gas.
The White House appeared concerned that momentum for the bill was slipping, though White House press secretary Robert Gibbs said that when it came time for a House showdown, "I'd bet on the president."
Democratic leaders scurried to line up enough votes to get the bill passed. They enlisted former Vice President Al Gore, the country's most prominent voice on the urgency of addressing climate change, to make phone calls to wary lawmakers - including some who believe the House bill was too weak rather than too strong.
House Republicans for weeks have maintained a drumbeat against the legislation, calling it a massive energy tax on every American and a "job killer" because it will force higher prices on electricity, gasoline and other energy sources as the economy shifts from cheaper fossil fuels, or as companies and utilities are forced to buy pollution allowances.
Obama as well as House Speaker Nancy Pelosi, D-Calif., sought to counter that argument.
"This is going to be a close vote because of misinformation out three that there's somehow a contradiction between clean energy and economic growth," said Obama. Rather than emphasizing any impact on pollution or global warming, he called the House legislation "a jobs bill" that will lead to the creation of new industries and "finally make clean energy a profitable kind of energy."
"It will create millions of new jobs," echoed Pelosi at a Capitol Hill press conference.
The Senate, meanwhile, was waiting for the House to act. Approval of a climate bill in the Senate has been viewed as a long shot because it would require 60 votes to overcome a certain filibuster. And that has made a decision by some House Democrats to vote for the politically charged bill even harder since final passage is so much in doubt.
The legislation would require the country to reduce carbon dioxide and other greenhouse gas emissions that can lead to climate change - by 17 percent by 2020 and about 80 percent by the next century. To do that, electricity producers and industrial plants would have to make a dramatic shift away from the use of fossil fuels through increased efficiency, move toward greater use of renewable energy or pay for ways to capture carbon emissions.
Democrats have sought to limit the economic impact with provisions that would make available pollution allowances to utilities and energy-intensive industries, and protect low-income consumers from higher energy costs by providing them rebates and credits.
But some Democratic lawmakers, from regions where utilities and factories rely heavily on coal, remain worried about higher energy prices and the impact that might have on voters.
Still other Democrats complain the bill has been watered down too much with concessions to garner broader support. Gore was said to be making calls from his home in Tennessee to shore up support among those lawmakers as well as others still on the fence.
Gibbs said Obama was calling lawmakers, too, although he declined to give any names. Carol Browner, the White House coordinator on energy and climate, also was on the phone to Capitol Hill as was chief of staff Rahm Emmanuel.
Lobbying on both sides of the issue intensified this week as Pelosi said she wanted a bill finished before lawmakers left for the July 4 holiday recess.
While most environmental groups as well as a number of business organizations and corporations have endorsed the bill, other industry groups, including the American Petroleum Institute and the U.S. Chamber of Commerce have called for its defeat. Despite the concession to farmers, the American Farm Bureau Federation said Wednesday it remains opposed, calling the bill "seriously flawed."
The bill's sponsors have been horse trading with a succession of Democratic lawmakers.
In a nod to farm groups and the ethanol industry, the bill's sponsors agreed to bar the EPA for at least six years from considering international land use changes when determining whether corn ethanol is a climate-friendly fuel. Environmentalists have argued that corn ethanol emits more greenhouse gases than conventional gasoline if global land use changes as a result of greater corn demand are taken into account.
And farmers were assured more favorable treatment in how pollution "offsets" are managed. These are credits farmers can sell in exchange for planting trees or adopting practices that sequester carbon in the ground.
A provision was included to allow businesses greater access to federal forests by broadening the definition of "biofuels" to include salvage lumber and brush from federal forests.
Rural electric cooperatives, who had argued they were being treated unfairly in the distribution of emission allowances, won an agreement to funnel more allowances their way.
Still the issue of future energy prices and the potential economic - and political - fallout of climate legislation dominated lawmakers' concerns.
"What we see is a job killer. ... There's no question that cap and trade will cost millions of jobs," said House GOP Whip Eric Cantor of Virginia, seeking to rally opposition to the bill. "There's no question the cap-and-trade will cost millions of jobs" and higher energy prices.
