Harvard University has done a study that by just performing two search queries using Google, is comparable to producing the same amount of carbon dioxide as boiling a kettle of tea.

The ‘waste product’ comes round to 15g of CO2 from our computers.

And with some 200 million search queries a day on Google, that electricity consumption and gas emissions all combined is astronomical as claimed by Harvard.

Google has responded to Harvard theory claims as biased, citing, “In terms of greenhouse gases, one Google search is equivalent to about 0.2 grams of CO2. The current EU standard for tailpipe emissions calls for 140 grams of CO2 per kilometre driven, but most cars don’t reach that level yet.”
