What is a BDO Zone?

The BDO Zone Initiative is a certification and regional risk rating program that accelerates biobased economic development. It enables economic development agencies and communities to highlight regions that possess characteristics valued by biobased developers and investors and then promotes these pre-vetted development zones.

The BDO Zone ratings identify economically distressed communities that are best positioned for low-risk bioeconomy project development by utilizing federal, state and local tax incentives and considering the three pillars of a BDO Zone.

Like credit ratings, BDO Zone Ratings typically range from “AA” to “BBB”. Unlike credit ratings, however, a BDO Zone Rating scores risk related to three key attributes (or pillars) that are crucial for biobased project development:1) surplus of biomass, 2) low-risk supply chains, and 3) suitable infrastructure to support an operating plant.

Applicants for BDO Zone ratings undergo a rigorous and extensive due diligence process to rate supply chain risk using a framework of over 100 standardized, transparent, and validated risk indicators based on the BSCR Standards for biobased investment.
