Mitigation credit market · Virginia
The challenge
When credits aren’t readily available, or information is out of date, projects are delayed. Virginia’s permittees needed a clearer way to find and compare credits, and credit providers needed one place to reach buyers.
The work
Water Ledger Global won DEQ funding through a competitive process, developed SWaN with the Virginia Department of Environmental Quality and operates the exchange. Everyone sees the same facts: availability, price, credit serial codes and transactions.
The result
DEQ announced the public marketplace on 18 December 2025. Buyers can browse, compare and buy stream, wetland and nutrient credits with real-time availability and pricing, and sellers list in one place. DEQ describes SWaN as adding transparency and consistency to Virginia’s credit marketplace.
