Ostrom developed the project design documents, ensuring that the documents met the BC Carbon Program and FCOP requirements. It has managed all aspects of the carbon project since 2009, including all validations and verifications. Ostrom provides policy and project admin support to the Nanwakolas and the Great Bear Carbon Credit LP regarding all aspects of the carbon project. They also act as marketing and sales agents and sell Great Bear tonnes in the voluntary market.
All three of the sub-projects of the Great Bear are validated and verified. Tonnes were issued through the BC Carbon Registry, with over six million tonnes from Darkwoods verified to date.
