Key Points: Sally Benson

Why is Carbon Capture and Sequestration (CCS) important?

• Fossil fuels will continue to be the major source of energy for the foreseeable future
• Without CCs it will be difficult to meet emissions reduction targets of 50% to 80% by 2050

How much sequestration capacity is available?

• Estimates indicate sufficient capacity for sequestering emissions for over the next century
• Experience and research will improve reliability

Will it lead back to the atmosphere and how will we know?

• Seals providing a permeability and capillary barrier can retain buoyant fluids for geologic time scales
• Careful site selection and operations with regulatory oversight
• Many monitoring methods are available – with more to come
