In everyday driving, conventional cars create more pollution due to CO2 emissions, meaning that hybrids are significantly greener when they’re on the move, as they don’t use their internal combustion engines all the time. But, pollution is also generated during the manufacturing process, especially of the batteries. Since hybrid cars have more batteries, they create more pollution before they get to the showroom, and there’s also the matter of recycling the cells after they’ve come to an end of their lifespan. Also, if you’re driving a plug-in hybrid, you should be aware that electric power used to recharge it isn’t always as green as you would like it to be. Regardless, hybrid cars pollute the environment less. There’s also the matter of sound pollution, where quiet hybrids create less noise.
