On the effectiveness of private transnational governance regimes—Evaluating corporate sustainability reporting according to the Global Reporting Initiative

The increasing involvement of transnational companies (TNCs) in global governance has been both applauded for its potential to make governance more effective and criticized for lacking democratic legitimization. Hence we investigate the effectiveness of one transnational governance regime, corporate sustainability reporting according to the Global Reporting Initiative (GRI). We found that the GRI has been successful in terms of output effectiveness by promoting the dissemination of sustainability reporting, in particular among Asian and South American companies. However, the outcome effectiveness of the GRI is limited as reporting showed a rather uniform content across countries and sectors which does not reflect materiality considerations. As GRI reporting does not seem to have facilitated greater company-stakeholder interaction, its impact effectiveness is likely to be limited too.
