Carbon capture utilisation and storage (CCUS) and public perceptions: A systematic literature review

Abstract

Over time, carbon capture utilisation and storage (CCUS) projects have faced limited public acceptance, with projects being delayed due to public and policy opposition. Public concerns tend to focus on the perceived efficacy, potential risks, costs and benefits of CCUS projects. It highlights a need for further discussion and reflection on the various aspects of CCUS technologies and their implications for local host communities and the broader public. This systematic literature review utilises the Technology Acceptance Framework by Huijts, Molin and Steg (2012) to study public perceptions of CCUS globally, based on 88 peer-reviewed papers published between 2016 – 2024. It offers an updated perspective on positive, neutral and negative perceptions towards CCUS and the factors influencing them. Different public groups and aspects of the technologies are considered. Our findings suggest that positive perceptions are underpinned by trust in government and developers, as well as the establishment of fair and transparent decision-making processes alongside benefit sharing for local host communities. It confirms that knowledge and awareness of CCUS technologies may affect support. For CCUS projects to be validated in society, more transparent decision-making and proactive engagement about the technological options to reduce emissions in the battle against climate change will be required.
