Businesses interested in becoming a B corporation can start by taking an impact assessment for the social and environmental performance section, which gives the company a score on a 200-point scale in categories like governance, labor, community, environment, and customers. Businesses must score at least 80 points on the assessment to get the certification.
Additionally, there's a legal requirement to ensure that the B corp's best practices be able to survive leadership changes. Companies can also incorporate as a public benefit corporation in many states, which gives them a corporate structure that qualifies as a B corp.
Finally, the company also needs to meet a public transparency requirement.
