CO2 capture and storage become an interesting strategy to mitigate climate change by reducing CO2 emission from stationary sources and storing it in geological reservoirs. Taking into account that Brazilian territory contains many sedimentary basins suitable for CO2 storage, the study of the Brazilian potential for carbon sequestration is relevant. This paper aims to present results of the Brazilian Carbon Geological Sequestration Map (CARBMAP Project). CARBMAP’s goal is to identify appropriate sites for long term CO2 storage in petroleum fields, saline aquifers and coal seams by an integrated geographic information system (GIS) and to generate products that will allow direct and detailed analysis regarding the CCS chain (capture, transport and storage) in Brazil, based on the development of a GIS for CO2 source-sink matching. The Phase I of CARBMAP research began in 2006–2007 with the mapping of Brazilian stationary CO2 sources, using a geographic database. The Phase II is underway, and is characterized by quantitative and qualitative improvement of the GIS resulting in more accurate products.
