Concepts of justice and measures of well-being are increasingly used to evaluate the extent to which climate change adaptation is equitable and effective . AR6 employs evaluation frameworks based on both single and multi-criteria to assess adaptation effectiveness and consistency with principles of justice. Single criteria frameworks aggregate many attributes into a one number or ranking, often quantified using benefit-cost analysis or measures of social welfare. Existing decision processes often favour such single criteria, which also correlate well with many measures of social progress and sustainable development. Multi-criteria frameworks simultaneously report several different biophysical and socioeconomic attributes, which provides more information on potential trade-offs and synergies and can engage with emerging concepts of well-being.
