Britain and Sweden are on target for reducing global-warming gases, but other countries will have to toughen policies and rely on "carbon trading" to achieve their Kyoto Protocol goals by 2012, says a new U.N. report.
In the United States, meanwhile, emissions of so-called greenhouse gases climbed by 16 percent between 1990 and 2004, the U.S. Environmental Protection Agency said in its latest assessment. The United States, by far the biggest emitter of carbon dioxide and other gases blamed for global warming, rejects the Kyoto pact on reductions.
Against this backdrop of rising emissions and discord over what to do about them, delegates from more than 160 nations on May 26 wrapped up two weeks of semiannual U.N. sessions in Bonn, Germany, on how to confront the threat of climate change.
On one track, they began talks on a stricter regime of emissions cuts for Kyoto nations after the 2012 expiration of that 1997 agreement, named for the Japanese city where it was negotiated.
