CO2Stats Basic is a free tool that makes your website environmentally friendly. Whenever people view your web site or blog, they use electrically-powered computers and servers. To create electricity, power companies must burn fuels that emit carbon dioxide into the atmosphere and cause global warming. CO2Stats monitors how much electricity is being used to power your site, and then it "offsets" the emissions by investing in renewable energy projects that help to counteract global warming. Our offsets are funded by advertising sponsors who are committed to making the Internet more environmentally friendly.
The CO2Stats widget can be added to a Web site or blog just by cutting and pasting some code. Based upon visitor traffic, the service's ticker will count the carbons and then pay the equivalent in offsets to Sustainable Travel International. That nonprofit funds renewable energy and development in the developing world, in addition to green power projects in North America.
