Portfolio Audit

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 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.

Transparency and Verification: 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.

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. Each year we compile a list of every sale, check it in detail (and have our outside accountants check it in detail as well), and add up all the numbers to make sure that everything aligns.
