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).
Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
Headline climate-policy statute of the Martin rotating coalition, signed 23 July 2021. Binds the state to a 51% reduction in greenhouse-gas emissions by 2030 (vs 2018 baseline) and climate-neutrality by 2050, establishes five-year carbon budgets set by the Climate Change Advisory Council and approved by the Oireachtas, creates sectoral emissions ceilings (electricity, transport, built environment, industry, agriculture, land use), and strengthens annual Climate Action Plan obligations. Rolling carbon budgets for 2021-2025 and 2026-2030 adopted by government April 2022. Complements a pre-legislated carbon-tax trajectory rising €7.50/tCO₂ each year from €26 (2020) to €100 (2030), enacted in Finance Act 2020.
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.
