Systems and method for emissions control of a hybrid vehicle. An instruction to switch from a combustion engine power mode of the hybrid vehicle to an electric power mode of the hybrid vehicle is received 502. A temperature of a catalyst associated with a combustion engine of the hybrid vehicle is identified 504, where exhaust gases from the combustion engine are passed over the catalyst. If the temperature of the catalyst is at, or above 506, a threshold level, the hybrid vehicle is switched to the electric power mode 508, and the combustion engine is switched off 510. If the temperature of the catalyst is below the threshold level 506, the hybrid vehicle is switched to the electric power mode 512, and the catalyst temperature is maintained at, or above, the threshold level 514.
