Facebook reveals its carbon footprint

Facebook has, for the first time, revealed the carbon footprint of its operations and its more than 900m users’ likes, photo albums and status updates.

The data, published on Wednesday, shows that despite the social networking’s rising star, its carbon emissions are still a fraction of internet rival Google. Facebook’s annual emissions were 285,000 metric tons of CO2 equivalent in 2011, compared with Google’s 1.5m tons in 2010.
