B Corp certification is granted to for-profit companies by B Lab, a nonprofit, that meet high standards of social and environmental performance, transparency, and accountability. To be certified, companies must score at least 80 points on B Lab's assessment of their impact on workers, customers, community, and environment. Certification requires companies to amend governing documents to consider all stakeholders, not just shareholders. Maintaining certification involves reassessment every 3 years. There are over 4,000 certified B Corps across more than 75 countries.
