Google aims to go carbon-neutral by end 2007

Google Inc. aims to voluntarily cut or offset all of its greenhouse emissions by the end of the year, the Web search leader said on Tuesday . Google is one of a number of companies, including News Corp. and Yahoo Inc. that are attempting to cut emissions of gases scientists link to global warming. To make the cuts, Google is investing in energy efficiency, renewable energy like solar, and will purchase carbon offsets for emissions it cannot reduce directly, the company said. "On their own, carbon offsets are not capable of creating the kinds of fundamental changes to our energy infrastructure that will be necessary to stabilize global greenhouse gas emissions to safe levels," Google said on its Web site.
