Burning fuel cleanly still emits the exact same amount of carbon.

No, the point is that different chemicals have different impact on the atmosphere (e.g. CO2, CH4 (emitted by cows), NOx (emitted by diesel cars and coal burning), ...)

But I guess you could have outlet filters to try to scrub the exhaust?

I don't know of any technology that can do that and be fitted to a car/airplane.

You could scrub CO2 on the ground to counter the emissions on the plane/car. Fixed plants are certainly more efficient than mobile units.
