Carbon capture and storage (CCS) appears as a technology tool to help countries to get their CO2 emissions lower and accomplished targets by 2030. As any humankind activities, CCS must follow legal constraints. Those are important issues to be considered in order to put carbon capture and storage projects in place. Therefore, this paper aims to describe and analyze the legal and environmental aspects about CCS in Brazil. Our methodology includes comparative law method and a case study that is Salt Cave Offshore located in Pre-Salt area. First, we must understand propriety rights, including operational permitting and others issues; after considering the cycle of life’s projects, its development and appropriated managed, control and closing; finally, environmental and public participation during project running life. Our intent is to contribute to Brazilian discussion on CCS legal framework in order to avoid conflicts and draw answers which law should be applied.
