Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Revised Climate Act (Ilmastolaki 423/2022) enacted under the Marin government, replacing the 2015 climate framework. Legislated Finland's 2035 carbon-neutrality target into primary law — among the most ambitious headline targets in the OECD — with binding interim reduction milestones of 60% by 2030, 80% by 2040, and 90-95% by 2050 relative to 1990 baseline. Extended coverage beyond the burden-sharing (non-ETS) sector to include the LULUCF land-use sector, committed the government to prepare a medium-term climate plan each electoral cycle, and strengthened parliamentary reporting. Accompanied by accelerated peat-energy phase-out and scaled-up wind and nuclear permitting. Targets retained but implementation timelines partially softened under the Orpo successor government.
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.
