Summary/Abstract
Global experimentalist governance has emerged within and across a number of international regulatory regimes, but its potential contribution to the global governance of climate change remains largely unexplored. This article investigates the opportunities and barriers to developing global experimentalist governance approaches in the international regulation of climate change technologies, focusing on the recent framework for marine geoengineering under the London Dumping Protocol. It argues that, in the face of the limits of international law in dealing with uncertainty, multilevel distribution of power and regulatory disconnection, global experimentalist governance is attractive to catalyse adaptability, iterative learning, participation and cooperation. Such approach can help rethink the way international law deals with technological development, by emphasizing its problem-solving function.
