This article explores the space for public participation during the consenting process for a nationally significant wind energy or carbon capture and storage infrastructure project. Legal obligations to provide opportunities for public involvement in these processes can be found in national, EU and international law. However, an examination of strategic planning policy suggests that in practice, very little will be up for discussion at this stage. This is consistent with a certain mistrust of the public in high-level policy discourse on the technological change thought necessary for climate change mitigation. Legally entrenched rights to participate, coupled with limited opportunities to influence, create the danger that participation becomes a simple bureaucratic hurdle, frustrating for all concerned.
