  "textContent": "Methods and systems are provided for reducing emissions and improving fuel economy for vehicles participating in car-sharing models. In one example, a method comprises while a vehicle is stationary with an engine deactivated, actively raising a temperature of an exhaust catalyst positioned in an exhaust system of the engine to maintain the temperature of the exhaust catalyst above a threshold temperature until a subsequent request for engine torque to propel the vehicle is requested. In this way, cold-starts of engines for vehicles participating in car-sharing models may occur less frequently, and accordingly release of undesired emissions to the environment may be reduced.",
