  Carbon capture and storage (CCS) is an area of technology that has received national and international attention. CCS is seen by some as a way to reduce carbon dioxide (CO2) emissions into the atmosphere and thereby decrease the threat of global warming. Consequently, proponents have increased pressure on state and federal governments to make such reductions mandatory. Although the benefits of CCS...
