This report considers how analysis can inform and support decisionmaking in complex urban areas and focuses specifically on the difficult choices among startegies and allocation of resources in response to climate change and in pursuit of greenhouse gas emmissions reductions. This effort has been motivated by the analytical needs of projects that RAND is conducting in three urban areas in the United States with support from the John D. and Catherine T. MacArthur Foundation. These field studies are being used to test the practicality and utility of the methods and structuring of indicators proposed in this report. Following completion of the field studies, we will publish our results as a separate document. Our intent is for the methods and structuring of indicators proposed in this report. Following completion of the field studies, we will publish our results as a separate document. Our intent is for the methods and study results, if proven to be practical and useful to be broadly applicable to early-adopting practitioners and planners interested in shaping and implemnting effective urban responses to climate change.
