Carbon Capture and Storage (CCS) is a promising technology to help greenhouse gas emission mitigation. However, one of the greatest challenges for this technology implementation is the opposition from the population living near the potential sites. Despite the Brazilian geological potential for carbon dioxide injection, research investigating social site characterization or CCS public perception is almost non-existent in Brazil. Thus, this research aims to address this gap and analyze social factors driving CCS perception of the population living near potential sites in the Recôncavo Basin, state of Bahia, this being one of the first steps for social site characterization. Fifty-seven interviews were carried out near 10 CCS potential injection fields, focusing on questions about climate change knowledge, people’s previous relationship with oil exploration, trust in public and private stakeholders, belief in citizens’ influence and CCS perception. The results showed that the previous history of the community with oil companies is an important factor influencing people’s perception of private companies in general and CCS projects in particular. Another relevant social factor is the sense of empowerment in some communities that may respond with riots and obstruction of the project if they feel harmed by the companies. The results also suggest that communication can be a relevant factor for CCS perception, correcting some wrong assumptions about the technology. It is important to educate people not only about CCS but also about climate change and other environmental issues and, ethically, address all aspects, positive and negative, of CCS implementation.

碳捕集与封存（CCS）是一项有前途的技术，可帮助减少温室气体排放。然而，该技术实施的最大挑战之一是居住在潜在地点附近的人们的反对。尽管巴西有注入二氧化碳的地质潜力，但巴西几乎不存在调查社会场所特征或CCS公众认知的研究。因此，本研究旨在解决这一差距并分析社会因素，促使人们对居住在巴伊亚州Recôncavo盆地附近潜在居民的人群进行CCS感知，这是表征社会场所的第一步。在10个CCS潜在注入领域附近进行了57次访谈，重点关注有关气候变化知识的问题，人们以前与石油勘探的关系，对公共和私人利益相关者的信任，对公民影响力的信念以及对CCS的认识。结果表明，石油公司社区的先前历史是影响人们对私人公司的总体看法，尤其是对CCS项目的看法的重要因素。另一个相关的社会因素是某些社区中的授权感，如果他们受到公司的伤害，可能会引发骚乱和项目阻碍。结果还表明，交流可能是CCS感知的一个相关因素，从而纠正了有关该技术的一些错误假设。重要的是，不仅要教育人们关于CCS的知识，而且还要教育人们关于气候变化和其他环境问题的知识，并且从伦理上讲，应对正面和负面的所有方面，
