Leveraging transfers to strengthen climate cooperation under the threat of solar geoengineering

The authors explore the role of transfers in a model of international environmental agreements (IEAs) on abatement under the threat of solar geoengineering (SGE) deployment. Transfers can expand the set of stable IEAs, reduce SGE deployment and lead to efficiency gains by closing more of the abatement gap. The authors show that transfers are part of an indirect governance approach to limit harmful SGE deployment by increasing global emissions abatement.
