Carbon dioxide (CO₂) is the primary anthropogenic greenhouse gas (GHG). India’s CO₂ emissions are expected to increase 70% by 2025. Geologic carbon storage (GCS) offers a way to reduce CO₂ emissions. Here we present the results of a search for the most cost-effective GCS opportunities in India. Source-Sink matching for large and concentrated CO₂ sources near geological storage in India indicates one very high priority target, a fertilizer plant in the city of Narmadanagar in Bharuch District of Gujarat Province, India that is <20 km from old oil and gas fields in the Cambay Basin. Two pure CO₂ sources are <20 km from deep saline aquifers and one is <20 km from a coal field.
