The Development of the Voluntary Biodiversity Credit Market in the United States: Pilot projects, Challenges, and Links to Regulatory Precedents

Voluntary biodiversity credits are a new and growing approach to structuring and financing biodiversity investment. While biodiversity credits in different forms have a multidecadal history in a regulatory (offset) context, the voluntary market is in the early stages of piloting, market testing, and methodological innovation. Amidst this global growth and the ongoing Roadmap towards Nature Credits process in the European Commission, this session will review market and policy development in the United States, where pilots are underway in a variety of ecosystems and land ownership contexts, and practitioners are facing a challenging decline in public financing for biodiversity conservation. Several trends are supporting the growing interest in voluntary credits. First, an increase in corporate focus on biodiversity impact in their operations and supply chains, tied to the adoption of disclosure initiatives such as TNFD, SBTN, and for multinationals, the EU’s CSRD. Second, the demand for improved measurement, methodological rigor, and standardization of investments in restoration and preservation. Third, the recognition among conservation practitioners and advocates that new sources of funding are needed, beyond the traditional avenues of philanthropic (including corporate charitable contributions) and public funding. These shifts underpin the interest in alternative project structures and financing that voluntary credits can provide. Concurrently, the US’s legacy of policy innovation in regulatory offset markets for wetlands, streams, and endangered species habitat provide clear guidance (overlapping but often distinct from carbon credit practice) for core integrity principles that must be upheld for a robust and ecologically beneficial market, such as project durability, clear and robust additionality, monitoring protocols, third party verification, and ecological equivalence. The pilot projects to be discussed include American bison restoration on Tribal lands, credit development integration into sustainable forest management, and montane meadow wetland restoration. Project ideation, financing structures, marketing, restoration strategies, corporate engagement, and ongoing debates around credit use, corporate claims, proposals for voluntary offsetting, and “positive contributions” will be addressed as well.
