You can view a full list of our 10 carbon offset projects by clicking here. This truly exhilarating portfolio of projects includes a whole range of CO2 reducing ventures, from reforestation in Brazil and windturbines in the US to solar energy, landfill and biomass projects. For each project you can find out more by clicking on 'further information' under the respective project title. Taken together, these projects are expected to sequester CO2 to the tune of 3.4 million metric tons, equivalent to the annual CO2 output of 136,000 households!

All our offset project are verified according to at least one of the appropriate protocols such as the Voluntary Carbon Standard 2007, the Chicago Climate Exchange Offset Protocols, and the Gold Standard. All verifications include site visits, and include audits of the project data and project monitoring equipment. In particular, these audits verify how individual purchases are used to achieve the desired reduction in carbon emissions. After all, you want to be sure your money is well-spent, and we want you to have confidence in our projects. Moreover, all our projects meet the all important criteron of 'additionality', which ensures that they are responsble for extra greenhouse gas reductions that would not have happened without the money spent by our customers and sponsors.

If you are interesting in becoming carbon neutral yourself, you can do so by buying offsets; by doing so, we are committing to reduce your CO2 emissions to zero for either 1 or 3 years by investing in the above projects. You'll receive a certificate confirming that you have purchased these offsets, as well as our Greatest Planet bumper sticker testifying that you have become carbon neutral; you'll also be entered automatically into our monthly draw to win a 'Segway' human transporters, valued at $12,000 (£6,000) each.

Finally, we offer a generous refund policy; if you change your mind for any reason, we'll issue a full refund without asking why.
