Carbon Capture and Sequestration
Carbon capture and sequestration (CCS) is an important strategy to reduce greenhouse gas (GHG) emissions and mitigate climate change. CCS is a process by which large amounts of carbon dioxide (CO2) are captured, compressed, transported, and sequestered. The sequestration component of CCS includes CO2 injection into geologic formations (such as depleted oil and gas reservoirs, un-mineable coal beds, and saline formations) as well as use in industrial materials (e.g. concrete). CCS is distinct from biological sequestration, which is typically accomplished through natural and working lands management and conservation practices that enhance the storage of carbon or reduce CO2 emissions.
Studies by the Intergovernmental Panel on Climate Change (IPCC) and the California Council on Science and Technology (CCST) have shown that CCS has the potential to reduce carbon emissions by millions of metric tons, and may be an integral part of meeting California’s long term climate goals.
CARB has adopted a CCS protocol under the Low Carbon Fuel Standard (LCFS), describing the requirements that CCS projects must meet in order to generate LCFS credits.
