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!

Is it a plug-in hybrid? Then it’s certainly lower, as the plug-in power comes from a power plant, and those are all much more carbon efficient than an auto engine.
If not, then the hybrid is probably a little better. The mileage test procedure does include some slowing and stopping, (the “city” number) to reflect actual driving. Those slowing and stopping operations are much more efficient in a hybrid, as the car’s energu goes into the batteries rather than just into heat.
