A simple, mild and inexpensive catalytic system, DBU and benzyl bromide, was developed for the cycloaddition of epoxides to ambient CO2 under metal-free and solvent-free conditions and a wide range of epoxides was converted to the corresponding cyclic carbonates with good to excellent yields (81–95%).
