摘要：
CO2 fixation technologies such as mineral sequestration-that is, the storage of CO2 as carbonate rocks-are beginning to emerge as means to mitigate global climatic change. In this study, the Life Cycle Assessment (LCA) approach is applied to quantify the effective systemwide environmental impacts of CO2 sequestration in mineral rocks. Five alternative processes for mineral sequestration are compared in combination with various CO2 recovery technologies. SimaPro's Eco-indicator ' 99 ("Hierarchist-Average" version) is used for generating the impact assessment results and sensitivity analysis was carried out to compare the results with other possible weighting options. Finally, the sequestration effectiveness parameter was calculated for the various combinations of CO2 recovery and mineral sequestration options.
