Abstract: A growing number of countries have set ambitious climate targets and recognized the potential of CO2 geological storage. Brazil's goal is to neutralize carbon emissions by 2050. The Paraná Basin is one of the most favorable onshore sedimentary basins for geological storage of CO2 in Brazil. This extensive sedimentary basin presents a privileged location in the south and southeast regions, where the largest stationary CO2 emitters are concentrated. Our results showed Rio Bonito Formation siliciclastic deposits present pairs of reservoir-seal rocks with adequate thicknesses and depths for stratigraphic CO2 trapping. The screening allowed us to define a favorability map area, which will be the basis for subsequent detailing and characterization studies on the Rio Bonito Formation rocks and the location of CO2 injection sites, thus contributing to the mitigation of the impacts of this gas in climate change.
