Who are B Lab’s assurance partners and why were they chosen?

B Lab's approved Assurance Partners for the B Lab Standards V2 are TO-CERT and SCS Global Services. They conduct the independent audits required for B Corp Certification.

All Assurance Partners must meet rigorous approval criteria, including ISO 17021 accreditation, the international standard for organizations providing audit and management system certification. This ensures they operate with competence, consistency, and impartiality.

• SCS Global Services is a US-headquartered organization with global reach and decades of experience certifying companies against leading sustainability standards. They are approved to certify Medium to XX Large companies. B Lab first partnered with an independent SCS subsidiary through a competitive tender process in 2024 to help develop the third-party assurance model before approving SCS Global Services as an Assurance Provider.
• TO-CERT, a subsidiary of Genashtim (a Certified B Corp headquartered in Singapore), is approved to certify smaller companies. TO-CERT has worked with B Lab for more than four years, supporting the verification of over 11,000 companies across 90+ countries. Expanding this trusted partnership helps ensure high-quality, cost-effective certification remains accessible to smaller businesses.

Both organizations were selected based on their proven expertise, independence, and ability to deliver consistent, high-quality assurance at a global scale.
