Phasing out "super greenhouse gases," which mass emitters China and the United States have agreed to restrict, could curb global warming by as much as half a degree Celsius by 2050, a report said Wednesday. Issued on the sidelines of beleaguered UN climate talks in Bonn, the report said a new Sino-US deal to scale back hydrofluorocarbons (HFCs) "can make a difference". "Should we succeed in phasing out HFCs, there could be quite large benefits," Bill Hare, director of the Climate Analytics think tank that co-authored the report told journalists in Bonn.

Japan's parliament revised a law Friday concerning measures to combat global warming, to create a new plan for reducing greenhouse gas emissions. The government intends to produce by this fall the new plan to replace the guideline for meeting the Kyoto Protocol target that expired at the end of March. Prime Minister Shinzo Abe has called for revising the previous government's international pledge to cut greenhouse gas emissions by 25 percent from 1990 by 2020.

REGINA - Saskatchewan Premier Brad Wall says the province has game-changing carbon capture technology and he's trying to sell the idea to the world. Wall spoke today at an annual carbon capture conference in Pittsburgh. The premier says there was keen interest in a project at the Boundary Dam power station near Estevan. The plan there is to capture up to 90 per cent of CO2 emissions. Most of the CO2 captured from Boundary is to be used to push more oil out of the ground in what's called enhanced oil recovery.

LONDON (Reuters) - Britain replaced outspoken junior energy minister John Hayes on Thursday after only six months in the job as government efforts to overhaul the electricity sector and cut carbon emissions reach a critical juncture. During his brief tenure the Conservative Hayes clashed over policy with his boss, Secretary of State for Energy and Climate Change Ed Davey, a member of the Liberal Democrats. The two parties form Britain's ruling coalition.
