All hands on deck: the role of collaborative platforms and lead organizations in achieving environmental goals.

This study examines the effectiveness of collaborative platforms in supporting local collaborations for natural resource management. It also explores how governmental and non-governmental lead organizations adopt differing collaborative implementation approaches and how these variations influence outcomes. Utilizing a natural experiment and a difference-in-differences estimator, we evaluate if the Department of Energy's Clean Cities program functions as a collaborative platform to foster local-level Clean Cities Collaborations across the US, thereby improving air quality. Our findings suggest that Clean Cities Collaborations have a substantial and enduring impact on reducing air pollution. A series of subgroup analyses suggests that these environmental improvements are most noticeable in collaborations led by non-profits and regional government councils, rather than those directed by state and local governments. A complementary content analysis provides exploratory evidence that issue definition, collaborative group structure, and inclusive decision-making processes are crucial managerial factors that contribute to the environmental improvements. These insights pave the way for more effective management of collaborative governance on a larger scale. [ABSTRACT FROM AUTHOR]
