B Corporation (also B Lab or B Corp) certification of "social and environmental performance" is a private certification of for-profit companies, distinct from the legal designation as a Benefit corporation. B Corp certification is conferred by B Lab, a global nonprofit organization with offices in the United States, Europe, Canada, Australia and New Zealand, and a partnership in Latin America with Sistema B. To be granted and to maintain certification, companies must receive a minimum score from an assessment of "social and environmental performance", integrate B Corp commitments to stakeholders into company governing documents, and pay an annual fee based on annual sales. Companies must re-certify every three years to retain B Corporation status.
