Certified B Corporations are businesses that have been audited by the nonprofit B Lab and scored at least 80 points across five impact areas: governance, workers, community, environment, and customers.
Certified companies must also amend their legal governing documents to require directors to consider the impact of decisions on all stakeholders, not just shareholders. Recertification is required every three years, and scores are public.
B Corp is one of the most rigorous business-wide certifications because it evaluates the whole company, not a single product line. Notable examples include Patagonia, Allbirds, and Ben & Jerry's.
