Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
SB 253 (Climate Corporate Data Accountability Act) and SB 261 (Climate-Related Financial Risk Act), signed in October 2023, require US-organised companies doing business in California with revenues above defined thresholds to disclose Scope 1, 2, and 3 GHG emissions (SB 253, $1B threshold) and climate-related financial risks consistent with the TCFD framework (SB 261, $500M threshold). CARB is responsible for implementing rules; the regime represents the first US sub-national mandatory climate disclosure regime.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
