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.
New Zealand designed an on-farm pricing mechanism for biogenic methane (and N2O) under the He Waka Eke Noa partnership and successor government proposals between 2022 and 2024 — making NZ the first country to attempt agricultural greenhouse-gas pricing. Successive iterations included split-gas levies, collective vs farm-level reporting, and revenue recycling for emission-reduction technology, but political and farm-sector opposition delayed and ultimately reshaped implementation.
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.
