Corporate accountability in stakeholder capitalism is challenged by widespread purpose-washing and greenwashing. Firms can be classified by their commitment to duty-based purpose and their level of impact signaling into four types: profit-centric, profit masking, transitional purpose (“purpose-hushing”), and deep-purpose organizations. Empirically, many firms greenwash, though the extent varies by sector. A global 15-year panel of 7365 firms shows moderate levels of circular-product-design greenwashing, highest in Agriculture, Forestry & Fishing and FIRE industries. Stakeholders often fail to penalize greenwashing in stigmatized industries because they expect it, consistent with expectation-violation theory. Evidence identifies five practices to mitigate greenwashing accusations: secure internal buy-in, avoid award-based self-promotion, emphasize ESG innovation, frame impact through in-kind (not monetary) contributions, and leverage social norms. Accountability for climate commitments remains weak: among 1041 firms with 2020 emissions targets, 9% failed and 31% stopped reporting, yet market, media, and governance reactions were negligible—highlighting the need for stronger external pressure and enforcement.
