Thomas Hale, Professor in Public Policy, co-authored a paper published on Nature Climate Change. The paper looks at the effectiveness of action-oriented summits, which have become a major feature of global climate governance. Using a dataset of 276 climate initiatives, the authors show important differences in output performance, with no improvement among initiatives associated with more recent summits.

With these results, the authors hope to make an empirical contribution towards understanding the increasingly transnational nature of climate governance.
