二氧化碳当量

2010年，全球全年的温室气体排放量可能约为470亿吨二氧化碳当量。

Global annual emissions of greenhouse gases in 2010 are likely to be about 47bn tonnes of carbon dioxide-equivalent .

450情景寻求将大气中温室气体的浓度限定在450ppm二氧化碳当量。

This seeks to limit atmospheric greenhouse gas concentration to the equivalent of about 450 parts per million of CO2 .

如果想实现这一目标，那么到2050年时，全球平均排放水平必须从当前的人均约7吨二氧化碳当量降到人均2吨左右。

global average emissions have to be reduced from the present level of about 7 tonnes per capita of carbon-dioxide-equivalent to about 2 tonnes in 2050 .

全球温室气体排放总量已由1970年的287亿吨二氧化碳当量增加到2004年的490亿吨，远远超出过去65万年自然变化范围，全球气候变暖已是无可争议的事实。

The gas emission of carbon dioxide of the global greenhouse is amounted from 28.7 billion tons to 490 million tons . It is far beyond the range of natural variability over the past 65 years .

它是指个人、组织、过程、产品以及事件在特定的系统边界内的温室气体排放量，并以二氧化碳当量C02-e的形式计算。

It is defined as the quantity of the greenhouse gases ( GHGs ) expressed in terms of CO2-e , emitted into the atmosphere by an individual , organization , process , product , or event within a specified boundary .
