Electric vehicles themselves do not produce tailpipe emissions like traditional internal combustion engine vehicles. However, the production of electricity used to charge electric vehicles can generate emissions depending on the source of the electricity. If the electricity comes from fossil fuel power plants, then there will be emissions associated with the electricity generation process. Additionally, there are emissions associated with the manufacturing and disposal of electric vehicle batteries. Overall, while electric vehicles produce no emissions during operation, there are still emissions associated with their lifecycle. **
