Key Findings

The top three named research priorities were: continued advances in attribution science; localized attribution; and quantifying noneconomic loss and damage.
More work is needed to counter the structural, institutional, and disciplinary barriers that impede integration of scientific evidence into cases.
Scientists can better support litigation by improving communication, updating data-gathering protocols, and creating independent expert networks.

Climate litigation continues to expand and mature, underscoring the importance of scientific evidence to support legal claims across the world. Evidence— including findings from the Intergovernmental Panel on Climate Change and peer-reviewed research—is already being used broadly in case development, complaints, legal briefs, and court proceedings.

This report synthesizes information from interviews with 25 litigators, identifying 10 priorities for additional research to support climate litigation. We describe structural, disciplinary, and institutional barriers that are currently impeding full integration of scientific evidence and discuss approaches that scientists and the scientific enterprise can take to overcome them.
