California turned its zero-emission-vehicle mandate into a tradable credit market.
California sets a ZEV sales quota and lets automakers trade credits; EV makers like Tesla sell their surplus at ~100% margin.

the move
California's clean-car rules require automakers to sell an increasing share of zero-emission vehicles, but some makers sell few EVs and would face huge penalties.
The clever move was to make the obligation a credit: every EV sold earns credits, and credits can be bought, sold and banked. A maker that cannot meet its quota buys from one that can, so compliance is cheapest for the market as a whole.
That credit market became a revenue stream for pure-EV makers, especially Tesla, which sold excess credits to legacy automakers. Regulatory credits are roughly 100% margin and helped carry Tesla to profitability.
why it works
- Trading lets the mandate be met where compliance is cheapest for the whole market
- Bankable credits reward early, over-delivering firms instead of punishing them
- Credit sales turn a regulatory burden into a funding source for the technology leader
what transfers
Make a regulatory quota tradable and the market finds who complies most cheaply; a small netting rule turns an expensive mandate into a funding channel for the leaders.
what came after
About a dozen states follow California's rules, and the federal government and the European Union run similar credit systems. Tesla's annual regulatory-credit revenue has ranged from hundreds of millions to billions of dollars, and the design is now a fixture of global EV policy, though it remains politically contested.
