To become a certified B Corporation, a company must fill in the B Impact Assessment (a free online tool), reach a minimum score of 80 points and have that score verified by B Lab. B Lab is the non-profit network behind B Corp which has a global standards team.
As well as having a minimum score in the assessment, a company must also adopt a legal structure committing the company to consider the impact of their decisions on all stakeholders.
The B Impact Assessment (or BIA) covers five impact areas: Governance, Workers, Community, Environment and Customers. There is also an unscored Disclosure Questionnaire which offers the company a chance to disclose any negative impacts they have or do still cause. Once a company is certified as a B Corp they must recertify every three years and demonstrate continuous improvement. The assessment itself is updated periodically. We expect to see the next evolution of the BIA go live in late 2024.
