Certified B corporations are companies verified by B Lab as companies that achieve high standards of social and environmental efficiency. B Lab certifies companies based on ways that create value for non-shareholder stakeholders, such as their employees, the local community and the environment. Once a company crosses a certain threshold of success on these dimensions, it amends its corporate bylaws to include the interests of all stakeholders in the fiduciary duties of directors and officers. These steps show that the company follows a fundamentally different management philosophy than a traditional shareholder-focused corporation. Certified B corporations are socially responsible and show significant concern for the environment in which they operate, provide support to the local community and are focused on contributing to the development of society. They are not only concerned with financial growth and development and profit generation, but they have incorporated social responsibility into their business as one of their important business goals. Examples of good practice have shown that the adoption of the B Corp certificate enables a company that has a good market position, and the perception of that company in the public as socially responsible. So far, the largest share of companies have a certificate in the category of micro and small enterprises, and the certificate is the most widespread in the United States.
