Face­book comes clean on car­bon

Element - - Clean Technology -

The jug­ger­naut so­cial me­dia web­site has re­vealed the car­bon foot­print of its op­er­a­tions, pos­si­bly to show up its ri­val google.

The CO2 emis­sions from keep­ing Face­book’s 900m users up and run­ning equate to 285,000 met­ric tons of CO2 in 2011, com­pared with Google’s 1.5m tons.

72% of Face­book’s emis­sions come from the huge data cen­tres and en­ergy used to run them. Half of the power used is gen­er­ated by burn­ing coal and gas, which ac­counts for the high car­bon foot­print.

Av­er­aged out per user, the emis­sions equal 269 grams, or around the equiv­a­lent of a cup of cof­fee, said the com­pany.

Last year Face­book an­nounced it would build a green data cen­tre in Swe­den, tak­ing ad­van­tage of the coun­try’s cold cli­mate to keep servers cool.
