Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
Multi-year escalator committing Norway's CO2 tax on non-ETS emissions to rise to approximately NOK 2000/tonne by 2030 (real 2020 kroner), set in the Klimaplan 2021-2030 (Meld. St. 13, 2020-2021) under Solberg and carried forward and re-affirmed by the Støre government. Annual budget laws step the rate upward with parallel compensatory measures for fisheries and agriculture. Interacts with the EU ETS coverage of petroleum and industry via Norway's EEA participation.
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.
