E2 Round-up: Salazar under pressure as Cape Wind decision nears, oil leaks from sunken Gulf of Mexico rig site, and developing nations push for climate pact

* Oil is leaking into the Gulf of Mexico following last week's explosion of a rig 50 miles off Louisiana's coast

Officials are trying to contain an ongoing underwater oil spill that has followed the blast at a rig that subsequently sunk. The Coast Guard, in an update Sunday, announced that up to 1,000 barrels of oil a day could be leaking from a well pipe about 5,000 feet below the surface.

U.S. agencies hope to use remote-controlled underwater vehicles to plug the leak, Reuters reports.

Under a plan approved Sunday, “Four underwater vehicles have been deployed under the plan outlined by the Coast Guard and U.S. Minerals Management Service. They will dive unmanned to the ocean floor to activate a blowout preventer, a giant series of pipes and valves that could staunch the leak,” according to Reuters.

The Coast Guard has suspended its search for 11 missing workers believed to have been killed in the accident last week.

* Large developing nations are pushing for a global climate pact in 2010 or 2011

Officials from China, Brazil, South Africa and India met over the weekend.

“A group of developing countries, among the world's fastest-growing carbon emitters, said on Sunday a legally binding global agreement to limit climate change needed to be completed by 2011 at the latest,” Reuters reports.

“Environment ministers of the so-called BASIC bloc -- Brazil, South Africa, India and China – met in Cape Town to look at how to fast-track such a deal to curb global warming,” their story adds.

The countries said in a joint statement that they want a legally binding emissions pact completed at United Nations talks in Mexico late this year, or talks in South Africa next year.

Negotiators are considered unlikely to complete a final treaty at the Cancun, Mexico summit. UN talks in Copenhagen late last year laid bare deep fissures between rich and poor countries.
