Do you know, Google also produces CO2 (Carbon Dioxide)?
One Google search produces about 0.2 g of CO2. But since you hardly get an answer from one search, a typical search session produces about the same amount of CO2 as does boiling a tea kettle. Google handles about 1 billion search queries per day, releasing some 200 tons of CO2 per day.
