1. Developing a framework for the evaluation of geoengineering proposals

At the heart of IAGP's research was the development of a framework for evaluating geoengineering proposals within the broader context of mitigation and adaptation.

Our framework, presented in Briefing Note 1, is designed to be flexible and accessible, allowing it to be used by a wide variety of users including researchers and decision-makers. The questions that make up our evaluation framework challenge the user to consider the broader storyline and underlying assumptions associated with the geoengineering scenario that they are considering. By using this framework, users are also encouraged to both acknowledge that uncertainties are pervasive, and to revisit and reflect on the evaluation as conditions, knowledge and attitudes change.

Led by the Universities of East Anglia and Oxford, the development of this framework cut across all areas of IAGP research and drew on the expertise of all IAGP partners.
