美国有3亿人口,约占全球人口的5%,但美国排放的二氧化碳却占全球排放总量的24%.中国人口约占全世界的20%,所排放的二氧化碳仅占全球排放总量的13%.根据《京都议定书》安排,欧美等发达国家从2008年到2012年的二氧化碳减排指标分别是：与1990年相比,欧盟要减排8%、美国7%、日本6%、加拿大6%、东欧各国是5%—8%.
世界银行发表的统计数据表明,2006年前9个月,欧盟成交了7.64亿吨二氧化碳当量,而2005年全年的交易量仅为3.24亿吨.按照24美元的加权平均成交价格计算,欧盟配额的市场价值达到189亿美元,比上年翻了一番还多.而同期在美国芝加哥、澳大利亚新南威尔士和英国,排放交易也都呈现明显上升的趋势.去年4月中旬,欧洲气候交易所创下了每吨30欧元的纪录,但在5月中旬又跌破了10欧元,2007年的期货价格则已降到了4欧元.据统计,2006年的前三个季度,在CDM中,每吨二氧化碳当量的平均交易价格是10.4美元.

The United States has 300 million population, accounting for about 5 percent of the world's population, but the U.S. global emissions of carbon dioxide emissions account for 24% of the total. China's population accounts for about 20 percent of the world, the only global emissions of carbon dioxide emissions of 13 percent. According to the "Kyoto Protocol" arrangements, Europe and the United States and other developed countries from 2008 to 2012 carbon dioxide emission reduction targets are: compared with 1990, the European Union to 8 percent emission reduction, the United States seven percent, Japan 6%, Canada 6 %, Eastern European countries is 5% -8%.
The World Bank's statistics show that in 2006 the first nine months, the European Union were the 764 million tons of carbon dioxide equivalent, while in 2005 the annual trading volume was only 324 million tons. 24 U.S. dollars in accordance with the weighted average transaction prices, the EU quota-free market value of 18.9 billion U.S. dollars, more than doubled over the previous year. During the same period in Chicago, New South Wales, Australia and the United Kingdom, emissions trading are also significantly increase. Last year, in mid-April, the European Climate Exchange set a record of 30 euros per tonne, but in mid-May and fell below 10 euros in 2007, the futures price has been reduced to four euros. According to statistics, in 2006 the first three quarters of the CDM, a tonne of carbon dioxide equivalent of the average transaction price was 10.4 U.S. dollars
