Glycerol-1,2-carbonate is formally the cyclic ester of carbonic acid with glycerol and has aroused great interest as a possible product from the "waste materials" carbon dioxide CO₂ and glycerol (especially from biodiesel production) with a wide range of applications.

The currently unsatisfactory yields and complex process conditions in direct synthesis stand in the way of a further spread of glycerol carbonate as a solvent and molecular building block from renewable raw materials.
