CO2 Summit II: Technologies and Opportunities

Urgently reducing global greenhouse gas emissions (GHG) could be achieved by carbon sinks or negative emissions, i.e. removing CO₂ from the atmosphere and offsetting historical CO₂ emissions. Negative emissions can be achieved when CO₂ is captured from processes based on biomass feedstock (bio-CCS). Biomass withdraws atmospheric CO₂ through natural processes such as the photosynthesis. Capturing and permanently storing this CO₂ away from the natural carbon cycle enables a withdrawal of CO₂ from the atmosphere. Sustainable growth and harvest of biomass resources is critical to achieve carbon negativity and to allow for sound biomass regrowth. …
