Who would have thought that, globally, the IT industry produces about the same volumes of greenhouse gases as the world’s airlines do-rough 2 percent of all CO2 emissions?

全球范圍內，信息技術行業與航空業產生的溫室氣體總量相同——約占二氧化碳排放總量的2%，這有誰曾想到過？

Many everyday tasks take a surprising toll on the environment. A Google search can leak between 0.2 and 7.0 grams of CO2 depending on how many attempts are needed to get the “right” answer. To deliver results to its users quickly, then, Google has to maintain vast data centres round the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy。

許多日常工作對環境造成的損失大得驚人。每一次谷歌搜索能釋放0.2到0.7克的二氧化碳，這取決于為了獲得“正確”答案你試過多少次。為了迅速向用戶提供搜索結果，谷歌不得不在世界各地建立大型數據中心，安裝一臺臺強大的計算機。這些計算機不僅產生大量的二氧化碳，還釋放大量熱能，因此這些數據中心需要良好的空調設備，這甚至會耗費更多的能源。

However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much to be done, and not just by big companies。

然而，谷歌和其他大型技術供應商嚴密地監控其效果，并做出改進。監控是減排的第一步，仍有太多問題需要解決，并且不只是由大公司來解決。
