How are the standards governed

As a standards-based organization, B Lab follows international best practices and guidelines for standards development to ensure the highest levels of effectiveness, fairness and credibility of the B Impact Assessment. This includes having independent oversight of the BIA and releasing new versions on a regular basis to make improvements.

All content and weightings of the assessment are governed by an independent Standards Advisory Council (SAC) made up of ~20 members, each respected in the field for their wisdom and each with deep industry or stakeholder expertise. SAC membership is designed to have representation from individuals and organizations that both are materially impacted by the standards and have deep expertise in topics relevant to the ratings system. SAC membership application is open to the public via B Lab's website each term and all members and their affiliations are also made transparent. To see a current list of SAC and Advisory Committee members click here.

Prior to the release of each new version of the assessment B Lab conducts both a private beta and a 30-day public comment period to ensure that B Lab's stakeholders are being recognized in the standards development process and the general public has the ability to review and provide input on proposed standards.

Until 2016, a new version of the B Impact Assessment was released once every two years. The first version (V1.0) of the Developed Markets (DM) assessment was released on October 19, 2007 and V2.0 followed in January 2010 with two addenda focused on the green building and financial services industries. V3.0 was introduced in July 2011 and includes an assessment designed for companies in Emerging Markets (EM). Version 3.0 features integration with the IRIS taxonomy and the ability to rate a fund portfolio. V4.0 was introduced in January 2014. In V4.0 we reduced the number of questions in the operations section and increased the sophistication of the questions in the Impact Business Model Section. V5 was released in January 2016 and was focused on fixing broken individual indicators in the BIA.

For V6, the B Impact Assessment’s development cycle has transitioned from a two-year to a three-year process, with a scheduled January 2019 launch. Version 6, as an even-numbered version, will include a review and update of the methodology as a whole, in addition to updates to individual metrics.

B Lab is currently in the process of collecting feedback on the current version (Version 5) of the assessment and will develop new drafts of Version 6 for initial testing in the summer of 2018. A 60-day public comment period will then start in September 2018, with final review and anticipated approval for launch in January 2019.

Governance Structure 

Standards Advisory Council (SAC)     

Standards Advisory Councils (SACs) are independent governance bodies that develop and update the B Impact Assessments. Each SAC is comprised of industry leaders from sustainable enterprise, impact investing, government and academia. The Emerging Market and Developed Market SACs have authority over the content and weightings of the B Impact Assessment. Recommendations from SACs require a two-thirds majority vote by the B Lab Board of Directors to overturn.

Industry Working Groups

Industry Working Groups are ad hoc committees comprised of industry leaders that advise the Standards Advisory Council on the development of industry specific addenda to the B Impact Assessment. Previous working groups have focused on real estate, health & safety, and financial services. Recommendations from the Industry Working Groups require a two-thirds majority vote from the relevant SAC(s) to overturn.

B Analytics Advisory Committee

The B Analytics Advisory Committee includes investors, fund managers, and advisors who are leaders in impact investing and advises B Analytics management on product development, fundraising, and adoption.
