Actors and the Sociotechnical System of Enhanced Weathering

Explores the involvement of diverse sectors and actors across the lifecycle of ERW, and the resultant dynamics emerging within the sociotechnical system.

Part of Enhanced Rock Weathering: From Concept to Climate Solution
12 Aug 2026 11:30

In this episode, Professor Nicholas Pidgeon joins Ms Molly James to explore the role of actors and institutions in the emerging sociotechnical system of ERW. From agriculture to the mineral industry, the participation of diverse sectors can raise important questions about conflicting interests and distributional outcomes.

Molly discusses her most recent paper which came from interviewing nearly forty actors across the lifecycle of ERW. She elaborates on the use of institutional theory to surface the interests, assumptions, values, and beliefs of actors and what this can tell us about the emergent institutional arrangements. 

Together, they reflect on the characteristics of the current sociotechnical system and what this means for ERW.
