This depends upon how the electricity is generated. Electric cars powered by electricity from coal fired power plants reduce local CO2 emissions, but increase them overall.

Cars powered by wind, solar, nuclear, or hydrological power emit very little CO2.

Why do we need another form of energy for cars?

Carbon monoxide usage is accelerating the rate of global warming; other forms of energy are "cleaner".


Will switching to electric cars stop global warming?

No, the only way to stop global warming is if the big corporations release less carbon emissions. Electric cars run on electricity, most of which is generated by burning fossil fuels (coal, oil and natural gas). Fossil fuels are the main cause of global warming. City air is cleaner if we use electric cars, but the carbon dioxide emissions are rising from the power stations. When our electricity is generated from renewable sources (solar, wind, water, biofuels etc) or from nuclear energy, then the rate of global warming will slow and eventually stop.
