Public perception is one of the key barriers to deployment of CCS. Local opposition has derailed experiments and some of the first projects aimed at storing C02 in the ocean (Hawaii and Norway, see de Figuerido 2002) and onshore in underground storage (Barendrecht in the Netherlands, Schwarze Pumpe and Beeskow in Germany; Greenville, Ohio in the United States).
Research on public perceptions is, therefore, a vital aspect in the development and potential roll-out of CCS. Understanding public perceptions will depend on key drivers such as the source(s) of the information, the form(s) the information takes and the framing of policies to support CCS. Identifying the arguments concerning CCS that publics and stakeholders find most engaging and challenging and also the issues about which they are likely to be concerned and most interested is an important early step. Clarifying at the start of a project what publics and stakeholders think about CCS helps to develop inclusive engagement strategies and allows any potential concerns or issues to be addressed at the earliest stage.
A critical element in public engagement is developing research techniques that allow both stakeholders and the lay public to talk freely about CCS, whilst also, where appropriate, giving them the materials they might need to form an informed and considered opinion.
