The current climate regime, which focuses on reducing (net) emissions, can be improved in two ways. First, by breaking up the problem, and addressing each part separately, but treating all parts as a system of agreements, new possibilities emerge for enforcement. Second, by incorporating adaptation, "geoengineering," and the risks associated with mitigation options (such as long term storage of nuclear waste and carbon dioxide) in a portfolio of agreements, more opportunities open up for risk management. A portfolio system of climate treaties would be superior to today's single-track architecture.

Scott Barrett offers a multi-pronged policy approach to address global climate change. He calls for pledges of "appropriate measures" such as emission mitigation actions with subsequent multilateral reviews. Such a pledge and review system would not carry binding consequences for non-compliance, but instead rely on moral suasion and naming and shaming in the international arena.
