Doctrine — stated goals and content

Sub-national regulatory laboratory assembling a durable climate stack: AB 32 Global Warming Solutions Act (2006, 1990-level emissions target by 2020); SB 375 (2008, regional transport-land-use planning); AB 398 (2017, cap-and-trade extension to 2030); SB 32 (2016, 40% below 1990 by 2030); SB 100 (2018, 100% zero-carbon electricity by 2045); AB 1279 (2022, statewide carbon neutrality by 2045); Advanced Clean Cars II (2022, ZEV-only new vehicle sales by 2035, CARB waiver); SB 253 and SB 261 (2023, climate disclosure on large firms doing business in CA). Cap-and-trade is linked with Québec via WCI. California exercises Clean Air Act §209 waivers to set vehicle standards stricter than federal, adopted by ~17 other states — a genuine laboratory-of-federalism channel. Revocation and restoration of the CAA waiver across federal administrations (Trump I revoked 2019; Biden restored 2022; Trump II moving to revoke again in 2025) is a live institutional contest over sub-national regulatory authority.

Policy-content fingerprint — how the framework codes this movement on its axes

↑
environmental stringency
regulatory.environmental_stringency
Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
increased · strong
more stringent environmental rules
Most stringent sub-national climate regime in the US; legally binding economy-wide targets plus sector mandates.
↑
sectoral licensing
regulatory.sectoral_licensing
Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).
increased · strong
tighter sectoral licensing / more state gating
Cap-and-trade allocation, ZEV credit regime, disclosure rules function as sectoral licensing architecture.
↑
sectoral subsidy
fiscal.sectoral_subsidy
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
increased · moderate
expanded sectoral subsidies
Auction proceeds earmarked for climate investments via Greenhouse Gas Reduction Fund; EV rebates and grid-investment subsidies.
~
energy supply security
regulatory.energy_supply_security
Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
mixed · moderate
SB 100 grid transition has surfaced supply-reliability stress (August 2020 rolling blackouts, Diablo Canyon extension reversal 2022) — honestly coded as mixed rather than purely negative.

Notes

The waiver-and-revocation dynamic is the framework-relevant institutional feature: California's stringency level is coded on policy content, but its reach beyond CA depends on a federal waiver whose contested status is itself a separate institutional-axis signal.
