1. A plasticizer composition, comprising
a) a recycled phthalate-based compound as a first plasticizer;
b) a cyclohexane dicarboxylate-based compound as a second plasticizer, and
c) a citrate-based compound as a third plasticizer,
wherein the first plasticizer has an acid value of 0.175 KOH mg/g to 0.27 KOH mg/g,
wherein 100 parts by weight of the plasticizer composition comprises 5 to 85 parts by weight of the first plasticizer, 10 to 90 parts by weight of the second plasticizer, and 5 to 85 parts by weight of the third plasticizer,
wherein the plasticizer composition has an acid value of 0.12 KOH mg/g or less, and
wherein carbon emission reduction rate of the plasticizer composition is 2% or more, which is calculated by Equation 1 below:
Carbon emission reduction rate (%)=100−[(A1/A2)×100]  [Equation 1]
In Equation 1,
A1 represents carbon emissions (tCO2 eq/MT) with respect to the plasticizer composition, and
A2 represents carbon emissions (tCO2 eq/MT) with respect to a control plasticizer composition.
