B Almost 200 countries met for two weeks in Copenhagen, Denmark at a United Nations conference on climate change. It was due to conclude a deal designed to set a carbon cutting framework to cover 2012-2050. In the end, only five of them reached an agreement: the United States, China, India, Brazil and South Africa. President Obama praised the agreement last Friday. He said, “Many people are disappointed in the agreement, but the compromise is better than nothing.” The voluntary agreement, known as the Copenhagen Accord, urges major polluters to make deeper cuts in the emission(排放) of greenhouse gases. Greenhouse gas emissions, such as carbon dioxide, are partly created by burning oil and coal for transportation and electricity. The agreement sets targets to prevent the Earth’s average temperature from rising more than two degrees Celsius above pre-industrial levels. And the plan calls for 100 billion dollars a year in aid to poor nations to deal with climate change. This would start in 2020. But the agreement is not legally binding(约束). It fails to set detailed targets for cuts in carbon emissions. And it failed to earn the support of all the nations at the talks. India’s environment minister praised the united position taken by India, China, Brazil and South Africa. He said it permitted them to avoid the legally binding targets and international supervision proposed by developed countries. India has promised to cut emissions by at least twenty percent but they say rich nations created the problem, so they should take most of the responsibility for reducing greenhouse gases. China rejected accusations that it was responsible for the results at Copenhagen. A Foreign Ministry spokeswoman said developed countries didn’t perform well at the talks. She said China has taken its own measures to fight climate change and supports pressing ahead with international cooperation. China and other large developing countries have accused rich nations of failing to offer big enough cuts in their own emissions. They also say wealthy nations did not offer enough money and technology to help poor countries deal with climate change. In Europe, politicians and environmentalists expressed deep disappointment that world leaders failed to reach a stronger agreement. United Nations Secretary General Ban Ki-moon says the Copenhagen Accord is only a beginning, and that he will work with world leaders to reach a legally binding treaty(条约) in the coming months. 46.
