Zerofootprint is a non-profit that “combines the best financial engineering, environmental engineering, social networking tools and business intelligence to create products and services that help large corporations, organizations and individuals significantly reduce their environmental footprint.”
Zerofootprint sells carbon offsets and also raises awareness about Global Warming by leveraging technology. They offer widgets, white-label web solutions, and other tools to help get Global Warming on everyone’s radar. Their website also features a community based website and a blog.
The carbon offsets idea is similar to the Terrapass model but Zerofootprint goes an additional step further by leveraging Web 2.0 tools to fight Global Warming.
