Carbon capture and storage (CCS) can contribute to global efforts to combat climate change. However, it remains a controversial technology that often faces public resistance Social acceptance of CCS  is a prerequisite for the further development and dissemination of this technology. In light of this, the MOF4AIR project -among others - explores this issue. The project is funded from the European Union’s Horizon 2020 research and innovation program and gathers 14 partners from 8 countries to develop and demonstrate the performances of MOF (Metal Organic Framework)-based CO2 capture technologies in power plants and energy-intensive industries. To examine societal perspectives, a quantitative social survey focusing on the general public (performed during January-February 2022 by a surveying company from the 7 MOF4AIR European countries was performed. The study aimed to examine various CCS-related aspects, such as citizens’ knowledge, general perceptions towards CCS, and social acceptance of CCS infrastructure. In addition, the study aimed to identify the factors significantly affecting the above-mentioned aspects, while taking into consideration distinct scenarios in terms of the country (Belgium, France, Greece, Italy, Norway, Turkey, the United Kingdom), infrastructure, acceptance dimension, and theme-related differences. The results of the general public’s social survey indicated that significant differences occur between the 7 countries in the vast majority of the themes under investigation with Norway being the country differing mostly within the group of countries. The overall level of CCS knowledge was rather balanced (evenly distributed above-average, and below-average knowledge), while general perceptions of CCS (in terms of how useful, valuable, and acceptable CCS is) were mainly positive. Respondents’ perceived attitudes towards CCS infrastructure on a national level were found to be rather positive.  .
