1. A plasticizer composition, comprising
a) a recycled phthalate-based compound as a first plasticizer; and
b) a citrate-based compound as a second plasticizer,
wherein the first plasticizer has an acid value of 0.175 KOH mg/g to 0.2 KOH mg/g,
wherein 100 parts by weight of the plasticizer composition comprises 15 to 90 parts by weight of the first plasticizer, and 10 to 85 parts by weight of the second 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 5% or more, which is calculated as in 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.
