Environmental concern-based site screening of carbon dioxide geological storage in China

Abstract Environmental impacts and risks related to carbon dioxide (CO2) capture and storage (CCS) projects may have direct effects on the decision-making process during CCS site selection. This paper proposes a novel method of environmental optimization for CCS site selection using China’s ecologic...
