No, even if you're charging your batteries with carbon-emitting power plants, those plants are much more efficient than the engine in a car or plane. Internal combustion engines are very impressive technology, but they are constrained by their form factor, and can't possibly extract as much energy from fuel as a large power plant. In reality, almost every power grid in the world is already cleaner than an internal combustion engine, and rapidly becoming cleaner as more renewable energy is deployed.
