TerraPass project portfolio

To ensure maximum transparency and accountability, every TerraPass offset purchase and marketing claim is verified in an annual audit conducted by an accredited third party. For the years 2004-2006 this report was conducted by the non-profit Center for Resource Solutions (CRS), creator of Green-e, the nation's leading renewable energy certification program. TerraPass now uses another independent auditor, but adheres to the same audit principles. The audit covers several aspect of our business:

• Purchase history. Do we actually buy the necessary amount of carbon offsets on behalf of our customers? To ensure that we do, the auditor examines our customer records and offset purchase contracts.
• Offset quality. Do we adhere to the quality metrics that we say we support? The auditor examines our carbon offset portfolio to ensure that it meets our stated standards.
• Consumer protection. Do we publicly disclose the contents of every TerraPass purchase? The auditor requires that we include a product content label with every TerraPass purchase, which is sort of like an ingredient list alerting customers to exactly what they're buying.

The project portfolio listings below are part of our audit submittals. We publish each year's full portfolio once it has been validated by our auditor.
