Across the world, over 10,000 Certified B Corporations are proving that business can be a force for good—but lasting systemic change requires more than individual action. This applied research, conducted in partnership with B Lab U.S. & Canada, examines how the B Corp movement can strengthen policy advocacy and collective action to drive systemic change. Led by Steven Deheeger, a Harvard graduate student and Trained B Consultant, the study draws on academic research and in-depth conversations with movement leaders to generate practical, actionable insights for the B Corp community.
