Obama to plead US case at global warming summit

WASHINGTON (AP) - Putting his prestige on the line, President Barack Obama will personally commit the U.S. to a goal of substantially cutting greenhouse gases at next month's Copenhagen climate summit. He will insist America is ready to tackle global warming despite resistance in Congress over higher costs for businesses and homeowners.

Obama will attend the start of the conference Dec. 9 before heading to Oslo to accept the Nobel Peace Prize. He will "put on the table" a U.S. commitment to cut emissions by 17 percent over the next decade, on the way to reducing heat-trapping pollution by 80 percent by mid-century, the White House said.

Cutting U.S. carbon dioxide emissions by one-sixth in just a decade would increase the cost of energy as electric utilities pay for capturing carbon dioxide at coal burning power plants or switch to more expensive alternatives. The price of gasoline likely would increase, and more fuel efficient automobiles - or hybrids that run on gasoline and electricity - likely would be more expensive.

Still, there is widespread disagreement over the cost to consumers.

Obama's promise of greenhouse emissions cuts will require Congress to pass complex climate legislation that the administration says will include an array of measures to ease the price impact. The bills before Congress, for example, would have the government provide polluters free emissions allowances in the early years of the transition from fossil fuels, as well as direct payments to many consumers facing high costs.

And, supporters of emission reductions say, there would be clear long-term health and environmental benefits from shifting the a clean-energy economy.

Carol Browner, Obama's assistant for energy and climate change, on Wednesday a cited a Congressional Budget Office study that said there would be $173-a-year estimated cost to the average household by 2020 if greenhouse gases were cut by 17 percent by then from 2005 levels. But the CBO analysis also said that if the cost-blunting measures in the legislation were not taken into account, the cost to households could jump to $890 per household.

Other studies conducted by pro-industry groups have put the average household costs at $900 to more than $3,000 a year, although many of those studies do not take into account new energy conservation efforts and assume a more pessimistic view of new technology development that could bring actual consumer costs down.

But slashing carbon dioxide emissions also could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies published this week in the British medical journal The Lancet. None of the studies - either those cited by the administration or those singled out by critics - attempt to gauge a "no-action" scenario that many scientists say will have significant economic costs as well.

The White House said Obama's decision to attend the international conference in Denmark was "a sign of his continuing commitment and leadership to find a global solution to the global threat of climate change."

But Obama's stopover on the conference's second day - instead of later when negotiations will be most intense and when most other national leaders will take part - disappointed some European and U.N. climate officials, as well as some environmentalists.

Others said Obama's personal appeal will resonate with the delegates from more than 75 countries and help reset the U.S. image on the climate issue after eight years in which the Bush administration staunchly opposed mandatory reductions in greenhouse gases.

Yvo de Boer, the United Nations climate chief, said it is important for the United States to establish emissions reduction targets and a financial commitment to helping developing countries address climate change.

"If he comes in the first week to announce that, it would be a major boost to the conference," de Boer told The Associated Press. He said Obama's participation was critical because delegates "are looking to the United States to come forward."

The president's first trip to Copenhagen - just last month - was less than fruitful. He made an unsuccessful pitch for the 2016 Summer Olympics to be held in Chicago.

Obama's participation had been in doubt since it became clear that the Dec. 7-18 conference was unlikely to produce a binding agreement, The original goal of the conference was to produce a new global climate change treaty to replace the 1997 Kyoto Protocol. But in recent weeks it became clear that delegates were likely to produce at best an outline for an agreement to be considered late next year.

The White House said Obama's commitment to a 17 percent emissions cut from 2005 levels by 2020 would be the first step toward an 80 percent reduction outlined in legislation before Congress. It said Obama is expecting "robust mitigation contributions" from China and other emerging nations as part of any final agreement.

Obama pressed for cooperation on climate change in meetings with Chinese President Hu Jintao in Beijing last week, and with Indian Prime Minister Manmohan Singh, during a state visit at the White House Tuesday.

China's top climate envoy said Wednesday his nation would seek binding pollution targets for developed countries but reject similar requirements for itself at the summit.

Yu Qingtai said it would be unfair for all countries to be required to combat global warming since most of the environmental damage has been caused by developed nations during their industrialization over the past 100 to 200 years.

The White House said it will send a half-dozen Cabinet secretaries to the talks, including Energy Secretary Steven Chu and Commerce Secretary Gary Locke, as well as the head of the Environmental Protection Agency, which is preparing regulations to cut greenhouse gases.

The high-profile delegation is intended to reinforce Obama's stance, despite the bitter debate in Congress. The House narrowly passed legislation requiring a cap on greenhouse gases from power plants and industry, but it's still unclear whether Senate Democrats will be able to muster the 60 votes needed to approve a similar bill.

Action in the Senate has been put off until next spring.

Administration officials don't want to repeat the mistake of Kyoto, when the U.S. agreed to emission reductions but never implemented them because of strong political opposition at home. The U.S. never ratified the Kyoto agreement.

Most environmentalists hailed Obama's decision to go to Copenhagen, even if it's early in the conference. They said it will help set the tone of the talks and reverse America's image internationally on climate change.

Said Michael Oppenheimer, a professor of geoscience and international affairs at Princeton University: "The U.S. has stood as the bad guy for so long that it's critically important for the U.S. president to set the tone for the meeting."
