Yeah I have a Subaru too and I've always thought that was silly. In their defense though, it's not just something they made up for marketing. Rather, it's a term for a silly thing California allows automakers to do to get around the requirement of selling actual zero-emissions vehicles: https://en.wikipedia.org/wiki/Partial_zero-emissions_vehicle https://en.wikipedia.org/wiki/Partial_zero-emissions_vehicle

This is akin to what I was thinking, in response to the grandparent's "This means what?" In California and like places, does it get you into the car pool / hybrid/ electric / bus lane? Is that part of why they colored it green -- so it looks like / is apparent that you qualify? P.S. Reading the Wikipedia link, I find the answer to my question: No. However, the warranty extension requirements look good to me -- having an older Subaru whose evaporative emmissions control system started to go wonky a bit after the 10 year mark. Something that can be bugger all difficult and expensive to diagnose and fix.

It’s a bit of a silly term but what it describes seems like a sensible thing. It’s meaningless if you’re only worried about CO2 but it’s significant when considering pollution that affects air quality.

  Right, I guess I’m just way more worried about CO2 than about smog.

    Why? Even the EU is moving away from emphasizing CO2 over particulate emissions.

      Because if we don’t dramatically cut our CO2 emissions quickly we’re irreversibly fucked? And part of that means moving away from ICE vehicles carrying a single person.

    That’s because efforts to improve air quality have been so successful.

Well, i mean, it's also silly in that it only considers tailpipe emissions. PZEV's are already required to have zero evaporative emissions, and besides SULEV tailpipe standards, also be cleaner than 90% of cars of the current model year ZEV's are required to have zero tailpipe emissions, and be cleaner than 98% of cars in the current model year. So ZEV's actually allow forms of emission that the PZEV may not. As long as it isn't an exhaust gas and one of the criteria exhaust gases.
