I believe there are quite a few Volvos that, when used in dense urban environments, emit cleaner air from the exhaust than they ingest.

I'm sure they love people believing that, but it's a cabin air purification system, and it's about PM 2.5 particles, not CO2.

There was a dutch EV prototype a few years ago that did include an active CO2 capture system as a proof of concept.
