Perspective: The UN Approval Process for Carbon Offsets

Green Car Congress

Verification of the emission reduction or carbon sequestration is critical in efforts to mitigate climate change. One question is who will be responsible for verifying changes in carbon, which raises questions about the role of a regulatory agency for accrediting claimed changes in carbon levels from an activity.
