Under CCS, carbon emissions are captured and permanently stored, for example in geological storage sites.
Carbon Capture, Utilisation and Storage (CCUS) is a method of reducing carbon dioxide emissions by trapping the gas for industrial use or permanent storage, preventing its release into the atmosphere.
Technology and nature-based carbon capture are two approaches that are viable and crucial tools needed to stabilise atmospheric concentrations of CO2.
