jats:titleAbstract</jats:title>jats:pThe concept of organizational accountability is central to good governance both domestically and internationally. However, assessing accountability in densely institutionalized global governance spaces requires new conceptual and analytical tools. Rather than concentrating on the accountability of states, intergovernmental organizations (IGOs), non‐governmental organizations (NGOs), and transnational corporations as distinct sets of global actors to whom different accountability criteria and mechanisms may apply, we want to focus on how growing overlap and interplay jats:italicamong</jats:italic> diverse global policy actors affects organizational accountability. And rather than focusing exclusively on accountability in terms of retrospective sanctioning based on fixed standards or legal obligations, we suggest that, in a densely institutionalized world, accountability also needs to be thought of as a prospective process. We therefore suggest a stronger focus on pluralistic, participatory, and deliberative forms of accountability that emphasize standard‐setting and responsiveness through collective deliberation, learning, and competition.</jats:p>
