What WAP Sustainability does

WAP Sustainability is a Nashville-based sustainability consulting, software, and data firm founded in 2009 by William Paddock and Brad McAllister, serving manufacturers, brands, retailers, healthcare organizations, financial institutions, and PE portfolio companies. The company operates an "outsourced sustainability department" model, providing managed services across Life Cycle Assessment (LCA), Environmental Product Declaration (EPD) development, carbon accounting, ESG advisory, material health, Cradle to Cradle certification, and product transparency. WAP holds multiple accreditations including CDP Silver Solutions Provider status, ACLCA-certified practitioners, Cradle to Cradle Assessor approval, and GreenScreen/HPD/Declare verifier credentials.

WAP's technology stack centers on the proprietary OpenEPD Format and three integrated products: Theta Core (LCA generation software with ERP/PLM connectors to SAP, Oracle, Autodesk, and Windchill), epd.world (EPD workflow and verification platform integrated with Program Operators NSF, ASTM, EPD North America, SCS Global Services, and Epsten Group), and the OpenEPD Database (a public repository with 400,000+ LCA/EPD records). The Scope-3 Database aggregates supplier-specific emissions data and is offered through API licensing. Revenue is generated through multi-year SaaS licenses, managed-service retainers, project-based consulting, and data licensing under quote-based enterprise contracts. Following the January 2026 acquisition by SLR International Corporation, WAP operates as a subsidiary within SLR's global environmental consulting platform, with the founding management retained.
