Hello, I am Stewart Macintosh with the BBC news. A report says scientist may have overestimated the level of carbon emissions in China over the past decade because of confusion about the type of coal being used there. Researchers said the discrepancy amounted to a significant proportion of global carbon emissions, here is Matt McGrath. "What this report has done is actually going to tested some of the coal that's actually been used there, and they found that the type of coal the Chinese are using has a lot less carbon than that people have been presuming. And so basically they have found it was like 40% less than the UN estimates. ______________________________________________________________ 大家好,这里是斯图尔特`曼斯托什为您报道. 相关报道表明,在过去的十年里,科学家可能因为不清楚中国所用的煤炭类型而对中国的碳排放量估计值偏高.研究者表示这个错误的估计占全球碳排放量相当大的比例,这里是麦格拉斯为您报道."报告基于中国实际所使用的煤炭做了测试,发现中国所使用的煤炭含碳量比他们想象的要低得多.从根本上来讲,他们发现这一数据比联合国估计的要少40%.____________________________________________________
