The present invention relates to a highly bio-based polycarbonate ester and a method for producing same. The highly bio-based polycarbonate ester has a bio-based carbon content of 80% or more since the highly bio-based polycarbonate ester is obtained by copolymerization of 1,4:3,6-dianhydrohexitol, which is a bio-based monomer derived from biomass, and 1,4-cyclohexanedicarboxylate and/or terephthalate, and therefore, the highly bio-based polycarbonate ester is not only human-friendly and environmentally friendly, but also advantageous in terms of biodegradability. |
