Moreover, where biodiversity offsets take a long time to mature, structuring reward purely on the delivery of biodiversity outcomes can affect the willingness of landowners to create offsets in the first place (Salzman and Ruhl, 2000). The MRV provisions used in practice frequently rely on the use of supplier self-assessments and independent third-party verification, though reporting may also be undertaken through public notification (Table 4.5). The Biobanking scheme in New South Wales, Australia, and the Compensatory Wetlands Mitigation and Conservation Banking schemes in the United States, conversely, all require offset suppliers to self-monitor offset progression against agreed performance standards and to submit self-monitoring reports to regulators at periodic intervals (NSW OEH, 2012, DOD and EPA, 2008, USFWS, 2003).
