Google aims to cut or offset all of its greenhouse emissions by the end of the year, the company says.
Google is one of a number of companies, including News Corp, that are attempting to cut all of their emissions of gases scientists link to global warming.
To
boost energy efficiency, Google is investing in renewable energy like solar and will purchase carbon offsets for emissions it cannot reduce directly, the company says on its website.
"On their own, carbon offsets are not capable of creating the kinds of fundamental changes to our energy infrastructure that will be necessary to stabilise global greenhouse gas emissions to safe levels," Google said on its website.
"But we believe that offsets can offer real, measurable, and additional emissions reductions that allow us to take full responsibility for our footprint today."
European companies invest in carbon offsets through the Kyoto Protocol's Clean Development Mechanism.
The United States did not ratify Kyoto, but some US companies have begun to offset emissions on a voluntary, unregulated basis.
The company says it will invest in projects like capturing methane, a greenhouse gas with about 20 times the warming potential of carbon dioxide, from animal waste at Mexican and Brazilian farms.
"Our funding makes it possible for anaerobic digesters to be installed, which capture and flare the biogas produced while simultaneously improving local air quality and reducing land and water contamination," Google said.
Nonprofit emissions advisers, The Climate Group, say they will partner with Google to support its offset plans.
"This is just a start," Google chairman and chief executive Eric Schmidt said in a release issued by The Climate Group.
"We are actively looking for more opportunities to help tackle climate change."
Google last week launched a program with semiconductor maker Intel to introduce more energy-efficient personal computers and server systems.
