Sorry if this is an exceptionally stupid question but I hope I’m in good company. If a hybrid vehicle gets 35 mpg, and there’s a comparable non-hybrid vehicle that also gets 35 mpg, do they effectively end up putting out the same amount of emissions? Or does it not really matter what the mpg is and there’s more to it? Thanks so much!

In terms of carbon dioxide emissions they will be exactly the same. However if the hybrid car is equipped with a plug in system you can still use less fuel then a conventional ICE car. But other tailpipe emissions like nitrus oxide, ozone and sot particles can still be quite different. And hybrid cars tends to be heavier so you get more dust from the tyres and asphalt which can also be quite devastating to the local environment. As for brake dust this can go either way, heavier hybrid cars need more braking power and will therefore make more brake dust but on the other hand they often have regenerative braking and will use their actual brakes less.
