Bridging the Gaps in the Polycentric Climate Change Regime
Global climate change is a key challenge to the global economy in the twenty-first century. To address it properly, a combination of mitigation and adaptation strategies is required. Although the responsibility for adaptation lies primarily with national governments (though, even here, poorer countries need international support), mitigation is one of the key fields of international cooperation. There is little chance that the fundamental objective of stopping global temperatures from rising more than 2 °С can be reached without a stable and comprehensive global governance system. The current international climate change regime based on the Paris Agreement is insufficient to prevent catastrophic climate change. Deeper cooperation between leading economies is especially necessary, including among those that are now reluctant to reduce greenhouse gas emissions.
