CO2 emissions definitely are a problem. Because carbon in the atmosphere causes climate impacts globally. Switching an ICE car to an EV car reduces carbon emissions significantly, perhaps by a factor of 2x to 5x. Particulate emissions are a separate problem. A local one but also important. Poor air quality contributes to diseases and deaths and EVs don't solve this one completely, although they do 1. reduce tailpipe particulate emissions (especially conpared to diesels) and 2. Use regenerative "engine braking" meaning less particulates from brake pad wear. However they still have tyre wear and that may be rather worse than an ICE car partly due to weight and partly due to immediate delivery of high torque to the drivetrain.
