CA’s requirement that it gets its own blend of gas is combined with how its openly hostile towards its ever decreasing refineries and that it is impossible for a new refinery to ever open makes it’s supplies absurdly limited
Whatever they're doing seems to be working nicely.
That ended a long time ago. A modern Honda generates something like 1% as much pollution as a car from the eighties.
The improvement in air quality is due to the clean air act, catalytic converters, and the shuttering of industry, the gas blend plays a minor part. Even then, with gas so much higher it will materially make peoples lives worse, at some point society would be better off getting rid of the blend.
How do you know California's lack of new refineries is due to California hostility rather than being due to whatever caused the same lack in every other state?
A big one is a lack of pipelines.
As I understand it, California sits on so much oil, nobody has built a pipeline.
Building an energy pipeline in California is like bringing sand to the beach. The energy is already there.
For example crude oil is produced mid state in the San Joaquin valley and pumped by pipeline to the Bay Area and LA refineries.
Refined product from LA is delivered by pipeline from LA refineries as far east as Phoenix and up to Las Vegas.
Building new pipelines in California though is…challenging.
