     carbon dioxide (co2) is the most important anthropogenic green house gas (ghg) responsible for global warming. it makes up almost 80% of anthropogenic ghg emissions. associated with the other ghg emissions, co2 has a major contribution to the global warming. co2 sequestration is used to describe both natural and deliberate processes by which co2 is either removed from the atmosphere or diverted from emission sources and stored securely. the sequestration options include direct injection into geological strata, terrestrial sequestration, ocean sequestration and mineralogical sequestration. injection into unmineable coal seams is one of the subsurface geological storage options. it involves co2 storage in uneconomic coal seams. the coal seams for co2 sequestration are better when the seams occur beyond a depth of 1 km. such depth provides the necessary cap rock to seal the stored gas from possible leakage. however, co2 sequestration is not advisable in a coal seam which may be mined in the future. this paper presents an analysis of rock formation in major coalfields of india and their suitability for co2 sequestration.
