Cross-border CO2 transport decreases public acceptance of carbon capture and storage

Carbon capture and storage is crucial to achieve net-zero targets and cross-border CO2 transport is essential for cost-efficiency of a carbon capture and storage strategy but how the public views this is unclear. Here, using multifactorial vignette experiments in four European countries and Canada, we show that cross-border transport hinders public acceptance of carbon capture and storage. Public concerns are unlikely to be offset by compensation, presenting a challenge for policy-makers. Carbon removal using carbon capture and storage (CCS) remains controversial. This study finds that cross-border CO2 transport would hinder public acceptance of CCS, associated with the perceived unfairness.
