Making two internet searches through Google produces about the same amount of carbon dioxide as boiling a kettle, it has been estimated.
Googling has 'a very definite environmental impact' according to research conducted by a physicist from Harvard University.
A typical search through the online giant's website is thought to generate about 7g of carbon dioxide. Boiling a kettle produces about 15g.
The emissions are caused both by the electricity required to power a user's computer and send their request to servers around the world.
