This paper explores the response by members of the lay public to the prospect of an onshore CO2 pipeline through their locality as part of a proposed CCS development and presents results from deliberative Focus Groups held along a proposed pipeline route. Although there is a reasonable level of general knowledge about CO2 across the lay public, understanding of its specific properties is more limited. The main concerns expressed around pipelines focused on five areas: (i) safe operation of the pipeline; (ii) the risks to people, livestock and vegetation arising from the leakage of CO2 from the pipeline; (iii) the innovative and 'first of its kind' nature of the pipeline and the consequent lack of operational CO2 pipelines in the UK to demonstrate the technology; (iv) impacts on coastal erosion at the landfall site; and (v) the potential disruption to local communities during pipeline construction. Participants expressed scepticism over the motivations of CO2 pipeline developers. Trust that the developer will minimise risk during the route selection and subsequent construction, operation and maintenance of the pipeline is key; building trust within the local community requires early engagement processes, tailored to deliver a variety of engagement and information approaches.
