  1. 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
