Schwarzenegger told delegates that U.S. states are embracing emissions caps even if the Bush administration isn’t. California’s Republican governor and Democrat-led Legislature have approved a law requiring the state’s industries to reduce greenhouse gases by an estimated 25 percent by 2020. “California is moving the United States beyond debate and doubt to action,” Schwarzenegger said. “What we are doing is changing the dynamic.”160Want local news?Sign up for the Localist and stay informed Something went wrong.

At the day’s end, he said he believed the scores of speeches showed a “major political commitment” to success in the global talks. Throughout, in remarks clearly aimed at Washington, the U.N. chief described the U.N. negotiating umbrella as “the only forum” where the issues can be decided. Ban organized the one-day summit to build momentum for December’s annual climate-treaty conference in Bali, Indonesia, when Europe, Japan and others hope to initiate talks for an emissions-reduction agreement to succeed the Kyoto Protocol in 2012. The 175-nation Kyoto pact, which the U.S. rejects, requires 36 industrial nations to reduce carbon dioxide and other heat-trapping gases. It set an average target of a 5 percent cut below 1990 levels by 2012 for emissions from power plants and other industrial, agricultural and transportation sources. On Thursday and Friday, Bush will host his own Washington climate meeting, limited to 16 “major emitter” countries, including China and India, the first in a series of U.S.-led gatherings expected to focus on those themes. UNITED NATIONS – With tales of rising seas and talk of human solidarity, world leaders at the first United Nations climate summit sought on Monday to put new urgency into global talks to reduce global-warming emissions. What’s needed is “action, action, action,” California’s environmentalist governor, Arnold Schwarzenegger, told the assembled presidents and premiers. The Bush administration showed no sign, however, that it would reverse its stand against mandatory emission cuts endorsed by 175 other nations. Some expressed fears that the White House, with its own forum later this week, would launch talks rivaling the U.N. climate treaty negotiations. President George W. Bush didn’t take part in the day’s sessions, which drew more than 80 national leaders, but planned to attend a small dinner Monday evening, a gathering of key climate players hosted by Secretary-General Ban Ki-moon.
