Global temperatures are increasing. Atmospheric CO2 concentrations are increasing. New carbon management legislation and initiatives are based on the assumption that increased CO2 levels are a major cause of global warming.
Several ways of reducing CO2 emissions and CO2 levels in the atmosphere include: improved efficiency in power generation by upgrading existing plants, higher efficiency in all new plants, relying more on renewable energy and nuclear-generated power, distribution of energy consumption among other resources and finally, carbon capture and storage (CCS). Of all emissions reduction mechanisms, CCS is projected to provide the largest contribution to emissions reduction in the near-term (~decade time scale).
