​Geothermal energy is heat derived from within the earth. Using this renewable energy for heating, cooling or power generation can help to meet CO2 reduction targets.

​​Carbon Capture and Storage (CCS) is a technology chain that forms a third pillar, along with renewable energy and energy efficiency, to reduce CO2 emissions to the atmosphere. It works by removing CO2 from the pre- or post-combustion exhaust gas of power stations and other industrial processes and injecting the CO2 into underground geological reservoirs of porous rock for permanent storage. While not eliminating our dependence on fossil fuels, it provides a bridging solution to mitigate the problem while renewable energy sources are developed to large-scale implementation.​
