• Rigorous techno-economic analysis of multiple mitigation measures for each baseline and mitigation target;
  
• More explicit analysis of policy instruments leading to mitigation;
  
• Inclusion of other GHGs in addition to CO₂;
  
• Analysis of the feasibility and costs of stabilizing atmospheric concentrations at levels other than 550ppmv CO₂;
  
• Explicit cost-benefit analysis of the impacts of timing and burden sharing on mitigation costs and targets;
  
• Quantitative analysis of linkages between DES targets (e.g., international equity) and climate change mitigation costs and benefits;
  
• More extensive attempts to link qualitative narrative-based scenarios analysis with quantitative modelling work; and
  
• Capacity building for scenario analyses in developing countries.
