- Builds consumer trust (90% recognition) and ESG credibility
- Mitigates regulatory risks from benchmarking laws
Implementation Overview
Phased approach: assess/gap analysis (4-8 weeks), design/testing (3-12 months), deployment, ongoing verification. Applies to manufacturers, building owners across sizes/industries; U.S./Canada focus. Requires lab testing, MESA partnership, annual recertification.
