Governing global problems under uncertainty: making bottom-up climate policy work

TLDR: The authors argue that given the great uncertainty of the feasibility and costs of potential solutions, this bottom-up approach will only work if it is supported by institutions that promote joint exploration of possibilities by public and private actors along with the scaling up of successes.

Abstract: With the failure of integrated, top-down bargaining strategies, analysts and diplomats have now turned to bottom-up methods such as “building blocks” and “climate clubs” to coordinate national climate change policies and to avoid persistent diplomatic deadlock. We agree that decomposition of the grand problem of climate change into smaller units is a crucial first step towards effective cooperation. But we argue that given the great uncertainty of the feasibility and costs of potential solutions, this bottom-up approach will only work if it is supported by institutions that promote joint exploration of possibilities by public and private actors along with the scaling up of successes. As politics precludes creating many of these institutions under the consensus-oriented decision rules of the UN system, engaged outsiders—including especially clubs or building blocks that can learn in the face of uncertainty—working in parallel with the UN diplomatic process will have to provide them.
