Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
First Nationaal Milieubeleidsplan (NMP) published 1989 set multi-year cross-pollutant targets covering acidification, climate, nutrient emissions and waste. Triggered collapse of Lubbers II (VVD withdrew over funding travel-pass for climate). Lubbers III enacted expanded NMP-plus 1990. Template for later NMPs and structural influence on Dutch environmental regulation architecture.
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.
