10 Mitigation commitments can have multiple dimensions Choice of time frame Headline number Coverage of sectors Choice of base year Coverage of gases 6 Use of units from market mechanisms Treatment of LULUCF Climate Change sources Expert and sinks Group Choice of GWPs or other GHG-equivalence metric

11 Bounded flexibility 7 Time frame GWP values Commitments relative to BAU? Source: HDNaturePictures.com

12 Ex-ante clarity of commitments Intensity goal Reduction from BAU Time frame Base year GWPs or other GHG-equivalence metric Coverage of gases and sectors LULUCF accounting Units from market mechanisms BAU emissions (i.e. without action) Expected future emissions (i.e. with action) GDP projections Definition of carbon neutrality Conditions attached Explanation of ambition (science, equity) Source of finance and domestic policies Other goal 8

13 Key questions What types of mitigation commitments could be proposed for the 2015 agreement? Is the concept of bounded flexibility useful for proposing commitments? What other information would be needed to understand the different types of commitments put forward, and what are the next steps? 9
