他说，“如果计入甲烷排放的因素，结果发现天然气仅仅能削减煤炭10%到20%的碳排放强度，那该怎么办？
What if, with revelations around methane emissions, it turns out to be only a 10 or 20 percent reduction of carbon from coal?
然而甲烷排放也与石油和天然气工业相关。
Methane emissions however are also linked to the oil and gas industry.
这些数据让包括美国在内的全球最富国家能够松一口气。根据协议，这些国家在2012年之前，需要将其排放量从1990年的基础上减少5.2%。
The figures will come as a relief to the world's rich countries which - the US aside - are legally committed to reducing emissions by a collective 5.2% on 1990 figures by 2012.
原因在于，额外的处理工序以及液化气的船运过程中将向大气中排放较多的温室气体。
That's because the additional processing and shipping of liquefied gas would put even more greenhouse gas pollution into the atmosphere.
天然气的二氧化碳排放量只有煤的一半。
如果把这些排放量全部计算在内的话，天然气也就比煤炭节省了25%的温室气体排放量，甚至会更少。
When all these emissions are counted, gas may be as little as 25 percent cleaner than coal, or perhaps even less.
换句话说，大气目前的承受量，仅能允许我们燃烧或排放已知储量四分之一的石油、天然气和煤。
In other words, there is only room in the atmosphere to burn or vent less than one quarter of known oil, natural gas and coal reserves.
如果用天然气发电，它比用煤发电排放的二气化碳量要少很多。
And plants powered by gas emit far less carbon dioxide than those powered by dirty coal.
