Are hybrid cars good for the environment?
How do hybrid cars reduce air pollution? It’s a question of emissions. As a general guide, petrol engines produce the most CO2 gasses and diesel engines produce pollutants, such as NOx, whilst hybrid cars have the lowest emissions.
Hybrid cars and their effect on pollution
How much a hybrid car is better for the environment than a conventional car is often subject to the size of the vehicle and the prevailing driving conditions. In comparisons between the same size and class of vehicle, say a compact city car, and driving in built-up city traffic, hybrid cars use substantially less fuel. They also have considerably lower emissions than conventional cars when running at any speeds.
