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?

　　全球范围内，信息技术行业与航空业产生的温室气体总量相同——约占二氧化碳排放总量的2%，这有谁曾想到过？

　　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.

　　许多日常工作对环境造成的损失大得惊人。每一次谷歌搜索能释放0.2到0.7克的二氧化碳，这取决于为了获得“正确”答案你试过多少次。为了迅速向用户提供搜索结果，谷歌不得不在世界各地建立大型数据中心，安装一台台强大的计算机。这些计算机不仅产生大量的二氧化碳，还释放大量热能，因此这些数据中心需要良好的空调设备，这甚至会耗费更多的能源。

　　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，谷歌和其他大型技术供应商严密地监控其效果，并做出改进。监控是减排的第一步，仍有太多问题需要解决，并且不只是由大公司来解决。
