Presentation transcript:

How to reduce atmospheric CO2? Reduce consumption of energy (production of CO2) Using alternative energy/renewable energy (changing in energy mix) Enhance the energy efficiency Development of technology Change in individual’s action Remove CO2 from atmosphere (sequestration, capture & storage (CCS)) Geological storage Ocean storage Mineral carbonation Biomass & soil
