Responsibility Under Uncertainty: Which Climate Decisions Matter Most?

Abstract We propose a new method for estimating how much decisions under monadic uncertainty matter. The is generic and suitable measuring responsibility in finite horizon sequential decision processes. It fulfills “fairness” requirements three natural conditions measures: agency, avoidance causal relevance. apply the to study matter stylized greenhouse gas emissions process which maker repeatedly faces two options: start “green” transition decarbonized society or further delay such transition. account fact that climate are rarely implemented with certainty their consequences on global economy uncertain. discover “moral” approach towards making — doing right thing even though probability of success becomes increasingly small rational over wide range uncertainties.
