According to the report just carrying out a typical search through Google can generate about 7 grams of carbon dioxide. Alex Wissner-Gross, the Harvard University professor that authored the report, says that even just browsing a basic Website can generate about 0.002g of CO2 for every second it is viewed. Sites with complex video can bring even more CO2 in the atmosphere, somewhere around 0.2g per second. But Google doesn't seem to be happy with the negative publicity the latest Harvard research brings. Only hours after the initial publishing, Google posted on their official blog an article explaining how they "have designed and built the most energy efficient data centers in the world," calling Dr. Wissner-Gross's research numbers "many times too high." Google also says that driving a car for a kilometer (0.6 miles) equates to the same amount of CO2 produced by a thousand of your Google searches.
Complete BS. Your PC that you are using to play games also is emiting CO2. You yourself is inhaling Oxygen and exhaling CO2.
