eng Available methods enabling chemical utilization of anthropogenic CO2 for production of cyclic carbonates using homogeneous non-metallic catalysts Cyclic carbonates are utilizable as green solvents, electrolytes in Li-ion batteries, intermediates for fine chemicals and monomers for polyesters or polyurethanes production. Cyclic carbonates are available by cycloaddition of CO2 into the epoxide (oxirane) ring. This reaction enables significant utilization of greenhouse carbon dioxide as the chemical building block. The synthetic pathways for both sustainable epoxides and cyclic carbonates production are described in this full text. This paper is focused mainly on description of applicable homogeneous non-metallic catalysts available for described CO2 cycloaddition. The most effective cycloaddition catalysts contain sources of nucleophile such as onium salt, structural moiety working as hydrogen bond donors and/or amino group(s) working as epoxide ring activators and CO2 scavengers for smooth CO2 addition and subsequent ring closure. In case of terminal oxiranes such as epichlorohydrin, even the flue gas (diluted CO2) is applicable for effective production of appropriate cyclic carbonates. cyclic carbonates, epoxide, cycloadition, CO2, catalysts, onium salt, quarternary ammonium halide
