The first part of the talk focuses on relevant work from the Climate Decisions Laboratory at the University of Pennsylvania.The Lab has developed nine quality of life evaluation criteria that are potentially pertinent to climate and sustainability policies. After discussing briefly the criteria and the underlying

philosophy of well-being (objective list), tying it to the UN’s Sustainable Development Goals, the talk describes two exercises in assessing scores for policies on the nine criteria, what the resulting rankings were, and how they were produced. The second part of the talk envisions an embedding context for this work, in which analysts, working independently but in effect collaboratively, arrive at prima facie credible multicriteria decision making (MCDM) models for comparing climate policies on quality of life. The aim here is not to decide for the public—an absurd goal—but to afford public deliberation by nudging it to focus in a productive manner and to provide tools useful for thoughtful deliberation.
