Google says it has wiped out its entire carbon footprint by investing in "high-quality carbon offsets".
It became carbon-neutral in 2007 and says it has now compensated for all of the carbon it has ever created.
Chief executive Sundar Pichai says they also aimed to run all of its data centres and offices on carbon-free energy by 2030.
Other large technology companies have also committed to reducing or eliminating their carbon use.
