Abstract: PURPOSE: A method for controlling emission of a vehicle is provided to stabilize emission by compensating fuel amount considering degradation index of catalyst and mileage index of the vehicle. CONSTITUTION: A method includes the steps of: a step(S101,S102) detecting concentration of oxygen contained in exhaust gas while an engine runs, and determining whether feedback control condition is satisfied; a step(S104) comparing catalyst degradation index with set reference value; and a step(S105,S106,S107,S108,S109,S110,S111,S112,S113,S114) determining whether oxygen is rich or lean after detecting the degradation index of the catalyst, and compensating fuel amount by calculating compensation coefficients. Compensating amount is calculated by calculation considering a proportional coefficient(K_p), an integral coefficient(K_l) and a gain value integral coefficient(K_LACCEL) mapped on a catalyst deterioration coefficient and throttle opening degree change rate depending on oxygen concentration when the degradation index of the catalyst is higher than the set reference value.
