Do hybrid cars emit carbon dioxide?

While hybrid cars emit less carbon dioxide (CO2) than conventional gasoline-powered vehicles, they still emit some amount of CO2. Hybrid vehicles use a combination of a gasoline engine and an electric motor to power the car. The electric motor is powered by a battery that is recharged through regenerative braking and the gasoline engine. When the gasoline engine is running, it emits CO2, although less than a conventional gasoline-powered vehicle. The amount of CO2 emitted by a hybrid car depends on several factors, including the driving conditions, the efficiency of the hybrid system, and the type of fuel used.
