B corporations (the B standing for "beneficial") are a type of organization proposed by B Lab of Pennsylvania. They use the power of business to create public benefit. B Corporations:

1. Meet comprehensive and transparent social and environmental performance standards;
2. Legally expand the responsibilities of the corporation to include stakeholder interests;
3. Build collective voice through the power of the unifying B Corporation brand.

To be classified as a B corporation under the B Lab system, the corporation must:

1. Achieve a minimum score of 80 (out of 200) on the B Ratings System, a tool to assess a company's social and environmental performance.
2. Agree to legally expand the responsibilities of your company to include consideration of stakeholder interests.
3. Go to bcorporation.net for the legal language appropriate to your state and corporate structure.
4. Sign the B Corporation Declaration of Interdependence and Term Sheet.
