Carbon Sequestration Certification Program
Verification is the process of determining if a practice or project is sequestering the amount of carbon dioxide that is claimed or expected to occur as a result of a particular activity. Verification is conducted by third party state approved verifiers -- not the offset provider, aggregator, or buyer. We have a 4-Level Verifier Training Program in place for participating Oklahoma conservation districts.
The Conservation Commission offers fee-based verification of Oklahoma agriculture and forestry offsets to state approved aggregators participating in the carbon program. Verification is also available to oil and gas operators conducting geologic sequestration of anthropogenic carbon dioxide.
Agriculture and forestry offsets verified by this program must have a management plan. For companies conducting geologic sequestration, verification includes assuring the project meets the requirements of the state and EPA's Underground Injection Control Program.
Verification of carbon offsets occurs in two phases:
- Field verification
- A verifier visits and visually assesses the offset or project site, takes pictures, and documents the field condition. We are working with OSU to collect soil samples from some fields for research purposes. The findings are not used to determine carbon offset value.
- Document verification
- Agriculture - Field verification forms and photographs of each field are reviewed to determine whether the practice is meeting the standard to sequester the expected amount of CO2. For rangeland, verification results and management records are used to determine adherence to the grazing management plan.
- Forestry - Field verification forms and photographs of each stand are reviewed to determine whether the forest stewardship plan is being adhered to.
- Geologic - Project-related documents are reviewed to determine if they substantiate the amount of carbon dioxide that an applicant claims to have sequestered. Includes mass balance calculation of injected and recovered CO2.
