We're talking about CA here. A single, albeit large, US state. As we see from emissions moving from the west to China, if CA imposes a tax then carbon emissions will just move somewhere else. The absence of a carbon tax in one US state likely has little effect on AGW. I would argue that interfering with market based production location may cause even more emissions as shipping costs may increase.
It actually helps them: They can import cheap goods from elsewhere and barely notice the cost.
I've noticed this in NYC - things are just so cheap relative to income that people don't care at all about items, they are very wasteful relative to other places I've been, and they kind of have to be, because they don't have much storage space. "Buy it, use it, toss it, buy it again when you need it." In contrast in places with more space (and lower income) people tend to store things for reuse.
But California is one of the largest and most advanced economies in the world. The same is true of Germany, which has been getting the California treatment recently. And both are currently performing very well given the global context (inflation, energy) and have proven tremendously robust historically, which makes these constant declarations of doom and gloom especially suspicious to me.
