Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
The November 2016 PSO-aftale and subsequent legislation phased out the Public Service Obligation (PSO) charge on electricity consumers — which had financed renewable-energy support — over 2017-2022, moving financing of renewable subsidies onto the general state budget. The reform responded to an EU-law challenge that the PSO levy was incompatible with free movement of electricity within the single market and was pitched as improving Danish business-electricity competitiveness. Fiscally neutral by design but institutionally significant: shifted renewable support from a ring-fenced consumer levy to general taxation and thereby politicised its annual quantum.
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.
