President Bush and leaders of the world's richest nations pledged Tuesday to “move toward a low-carbon society” by cutting greenhouse gas emissions in half by 2050, the latest step in a long evolution by a president who for years played down the threat of global warming.
The declaration by the Group of Eight – the U.S., Japan, Germany, Britain, France, Italy, Canada and Russia – was the first time that the Bush White House had publicly backed an explicit long-term target for eliminating the gases that scientists have said are warming the planet. But it failed to set a similar goal for cutting emissions over the next decade and drew sharp criticism from environmentalists, who called it a missed opportunity.
In a sense, the document represents an environmental quid pro quo. In exchange for agreeing to the “50 by 2050” language, Bush got what he has sought as his price for joining an international accord: a statement from the rest of the G-8 that developing nations such as China and India, which have declined to accept mandatory caps on carbon emissions, must be included in any climate change treaty.
European leaders, who have long pressed Bush to take a more aggressive stance on global warming, said the declaration could enhance efforts to reach a binding agreement to reduce emissions when negotiators meet in Copenhagen, Denmark, next year under U.N. auspices.
Never miss a local story.
“This is a strong signal to citizens around the world,” the president of the European Commission, Jose Manuel Barroso, told reporters. “The science is clear; the economic case for action is stronger than ever. Now we need to go the extra mile to secure an ambitious global deal in Copenhagen.”
The leaders of the eight industrialized countries, who gathered on the northern Japanese island of Hokkaido for their annual meeting, spent months debating the language of Tuesday's communique in lower-level negotiations. Critics said that it was short on specifics and that developed and developing countries would need to make much sharper cuts in emissions to head off the worst effects of global warming.
The statement left unclear, for instance, whether the cuts made by 2050 would be pegged to current emissions levels, or 1990 levels, as many advocates had hoped.
A 50 percent cut from current levels would result in a less significant decrease by 2050 than Japan and European nations had envisioned under the Kyoto Protocol, the international climate agreement that the Bush administration rejected after it took office. Kyoto and earlier agreements had set 1990 as the baseline for future cuts. The United States emitted about 20 percent more carbon dioxide in 2007 than it did in 1990.
“It is one step forward from the U.S. point of view, because President Bush has agreed that the United States, for the first time, must be bound by an international treaty,” said Philip Clapp, director of the Pew Environmental Group, who is here monitoring the negotiations. “But the emissions reduction goal is extremely weak; the language in the communique is almost meaningless.”
The White House painted the document as a victory.
“The G-8 is giving a lot, but the G-8 is also suggesting that others need to be part of that equation,” said James Connaughton, Bush's top adviser on environmental matters. “And that's a very important shared statement.”
