Britain's prime minister hopes to push the nation to the forefront of global efforts to tackle climate change, calling Monday for ambitious new climate change targets for cutting carbon emissions, according to AP. Gordon Brown, making his first major speech on the environment since taking office, said he would ask a committee of advisers to consider whether Britain can meet an 80 percent cut in emissions by 2050. «The climate change crisis is the product of many generations, but overcoming it must be the great project of this generation,» Brown told a meeting of the World Wide Fund for Nature. «While the richest countries have caused climate change, it is the poorest who are already suffering its worst effects,» he said. Brown also said Britain would encourage allies, such as the United States, to make similar pledges.
