The invention belongs to the technical field of polymer materials, and in particular relates to a production method of an environment-friendly polycarbonate. The production method comprises: S1 adding diphenyl carbonate, isosorbide and bisphenol fluorene into a reaction kettle, protecting with a nitrogen atmosphere, and then mixing to obtain a mixture; S2 adding a titanium-silicon molecular sieve composite catalyst to the mixture for transesterification reaction, then performing polycondensation reaction, pouring out the product while hot after the reaction, and cooling to obtain an intermediate product; S3 mixing and stirring the intermediate product, pyridine-type ionic liquid-modified hydrotalcite, rubber elastomer, compatibilizer and antioxidant to obtain a premix; S4 performing melt extrusion, strand drawing, water cooling, air drying, pelletizing and drying on the premix in a twin-screw extruder to obtain the environment-friendly polycarbonate. The polycarbonate produced by the production method not only has low chroma, but also has excellent impact resistance, heat resistance and flame retardancy.
