To ensure maximum transparency and accountability, every TerraPass offset purchase is verified in a periodic review conducted by an independent and accredited third party.  We were the first, and remain the only, carbon offset provider in the U.S. to undergo such a review of our carbon purchase and supply. 

The review covers several aspects of our business:

Offset quantity: Did we actually source the necessary amount of carbon offsets on behalf of our customers? To ensure that we did, the accountant examines and verifies our retail sales records and offset supply contracts.

Offset quality: Did we adhere to the quality benchmarks that we say we support? The accountant examines our carbon offset portfolio to ensure that it meets our stated standards.

Consumer protection: Did we publicly disclose the contents of every TerraPass purchase by including a product content label with every TerraPass purchase?  This is sort of like an ingredient list alerting customers to exactly what they’re buying.

Our published project portfolio list is part of our submittals to the independent accountant. We publish details on the full portfolio for each period once it has been verified by our accountant. Customers who choose a custom mix of project types, or who purchase through retail partners such as Expedia or Enterprise Rent-A-Car, are included as a subset of the overall portfolio.

Project feedback

Before TerraPass commits any project to its consumer offset portfolio, it undertakes a 30-day public comment period during which stakeholders and members of the public can give feedback on the project and its eligibility for a consumer offset portfolio.

2013 Project Portfolio

Status: pending

TerraPass has started the independent review process for customers who purchased offsets from January 1, 2013 to December 31, 2013. Results will be published soon.

Each year TerraPass retires the offsets it sold during the previous year. The time lag between sale and retirement occurs because of the process required to have third parties verify the exact amount of offsets generated and retired on behalf of our customers.

To give you a sense of what this looks like in real life, here’s what’s we are doing now and all year long.

We are visiting projects.  Each January, our project management team starts annual trips to projects to conduct verifications. That means we send them to all sorts of cold places (Michigan, Wisconsin, Upstate New York. We are hoping for more projects in Florida next year.) to check things out. Find out exactly what goes into a verification in this blog post.

We are counting beans (well, more accurately, offsets).  Each year we compile a list of every sale, check it in detail (and have our outside accountants check it in detail, too!), and add up all the numbers to make sure that everything aligns. Sure it is a lot of work, but no one said fighting climate change is easy.

Independent Carbon Portfolio Review

TerraPass’ retail sales and retirements of carbon offsets were independently reviewed by SingerLewak, a top 100 accounting services firm (out of over 150,000 nationally) headquartered in Los Angeles, CA.

TerraPass’ carbon portfolio for the period of January 1, 2009 through June 30, 2010 saw several changes from previous years. In addition to offsets from wind power, agricultural methane capture, and landfill gas capture, we added a new project type:  methane capture from an abandoned coal mine. Meanwhile, changes in the market impacted the supply of offsets from agricultural methane capture projects, thus resulting in a smaller percentage of such offsets in our portfolio than in previous years.

All projects meet our high standards for inclusion in the portfolio. In addition, we carried forward into this timeframe our final remaining offsets issued under the Chicago Climate Exchange program (CCX) so that they could be retired to honor specific requests from customers.  These offsets were not part of the general portfolio used to satisfy our individual and business sales.

The projects listed below detail the final portfolio for retail customers who purchased offsets between January 1, 2009 and June 30, 2010. See SingerLewak’s report for full details.
