Carbon capture and storage (CCS) proposals across the U.S. Gulf Coast raise questions about public acceptance, trusted messengers, and justice in communities with long industrial histories. A mixed-methods convergent study of adult residents in Louisiana, U.S. was conducted. A survey produced 466 responses, complemented by semi-structured interviews with 11 community leaders from government agencies, NGOs, and a private company. Ordinal outcomes used Mann–Whitney tests and local acceptance was modeled via logistic regression with familiarity, self-rated knowledge, concern and trust indicators, and demographic adjustors. Baseline understanding was low. Overall, 58.3% of respondents indicated they would accept a CCS project in their parish; acceptance did not differ significantly by age, gender, or income. Older and higher-income respondents reported higher familiarity and knowledge. The most frequent concerns were health risks, environmental injustice, economic impacts, and effectiveness; scientists and environmental organizations were the most trusted information sources, followed by government agencies and community leaders. In adjusted models, familiarity, trust in government agencies, and selecting economic impacts as salient were positively associated with acceptance. Qualitative responses emphasized independent monitoring, public dashboards, groundwater protection, and clear liability alongside auditable local benefits. Thus, acceptance is conditional on credible governance, transparent risk management, and tangible community benefits. Implications: This study offers important implications for environmental management, energy transition planning, and public policy regarding the deployment of Carbon Capture and Storage (CCS) projects in Louisiana. The findings demonstrate that public acceptance of CCS is not determined solely by technological feasibility, but also by social factors such as trust in institutions, perceived environmental and economic benefits, prior community experiences with industrial development, and the availability of transparent communication channels. The study therefore emphasizes that successful CCS implementation requires a people-centered approach that prioritizes stakeholder inclusion alongside technical and regulatory considerations. For policymakers and regulatory agencies, the results highlight the importance of incorporating community perspectives into project planning, permitting, and monitoring processes. Early engagement, accessible risk communication, and continuous public dialogue may help reduce misinformation, improve trust, and strengthen social license for CCS initiatives. For industry practitioners and environmental managers, the findings suggest that community benefit strategies, local employment opportunities, and visible environmental accountability can positively influence perceptions of CCS projects. The study also carries implications for environmental justice and sustainable energy transition efforts in industrial regions. In areas with long histories of petrochemical activities, communities may evaluate CCS projects through the lens of past environmental and social experiences. As a result, equitable participation, transparency, and responsiveness to local concerns become critical components of responsible CCS governance. Academically, this research contributes to the growing literature on public perception of emerging climate mitigation technologies by providing empirical evidence from a Gulf Coast context where CCS expansion is rapidly increasing. The findings may guide future studies exploring trust-building mechanisms, energy literacy, and community-centered approaches to low-carbon infrastructure development.
