- Uncertainty should be the key to designing sensible climate policy.
- Kyoto Protocol is the wrong approach because it is based on targets and timetables for emission reduction when the world is uncertain, so costs are unbounded and countries will not ultimately stick to their targets.
- National policies based on abatement and adaptation coordinated internationally is the way forward.
The author also proposes the alternative approach of national actions based around an international framework for assessing emission reduction policy. Critically, it is the latter approach which has now emerged from the Copenhagen Accord in 2010 and further in Durbin in 2011.
