Question 5513

Do vehicles with an electric motor emit gases that could harm the environment while they are running?

  1. No; they emit neither polluting gases nor greenhouse gases into the atmosphere.
  2. Yes, and the batteries they use are also highly polluting waste at the end of their useful life.
  3. No, but they use more energy during deceleration and braking.
Show answer and explanation

Correct answer: No; they emit neither polluting gases nor greenhouse gases into the atmosphere.

No. A battery electric car runs only on its electric motor and does not burn fuel, so it emits no polluting gases or CO2 while driving. When you take your foot off the accelerator or brake, the car recovers energy through regenerative braking, which partially recharges the battery. What happens to the battery at the end of its useful life does not change what the car emits while running.
