Resumo
In the light of what is intended for the coming decades, it is predicted that around 70% of the global energy base is still from fossil fuels, with this percentage expected to be maintained by 2050, which points to an increase and maintenance of GHG emissions on the planet, especially carbon dioxide (CO2), cause of the greenhouse effect. From the global outlook on environmental problems, as well as their forecasts, Carbon Capture and Storage (CCS) technology is an alternative in the effort to reduce GHG emissions on the planet. Because it is a technology with potential for implementation in Brazil, added to the difficulty in assuming and meeting GHG mitigation goals and the small amount of work on public perception regarding SCC technology in the country, this dissertation aimed to analyze the public perception about SCC technology from the opinion of professors and students in exercise in federal universities in southeastern Brazil, relating it to environmental awareness in the context of climate change. To obtain the data, a questionnaire elaborated entirely online was applied in federal universities in southeastern Brazil, answered by 671 individuals, among students and professors who work in the universities under study. For the synthesis of the data, a descriptive analysis of the results was performed to compare the answers, as well as hypothesis tests with different groups of the population to evaluate the existence of association between the variables of interest. The results showed that knowledge of SCC is still incipient, with only 7% of the population considered to have an understanding of technology. However, the largest proportion of respondents revealed that they accepted the technology (65%) and agreed that public resources (52%) should be injected into it. The results also point to a relationship between those who care about climate change and those who accept CCS, indicating that greater knowledge about technology can influence its acceptance, especially if the security aspects of technology are improved.
