Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).
Regulation (EU) 2021/1119 — the European Climate Law — codifies the Union's binding objective of net-zero greenhouse gas emissions by 2050 and an interim 55% net reduction below 1990 levels by 2030. It establishes a European Scientific Advisory Board on Climate Change, requires the Commission to align all EU legislation with the trajectory, and underpins the Fit-for-55 package implementing the target across ETS, transport, buildings, and renewable-energy regulation.
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.
