What the policy did

Cancellation of planned Danube hydropower plant at Hainburg following mass occupation of the Au wetlands by environmentalists, students, and public figures (including Konrad Lorenz and Günther Nenning) in December 1984. Court injunction then construction moratorium. The Hainburg site became the Donau-Auen National Park in 1996. Foundational moment of Austrian environmental movement and precursor to Green-party entry to parliament in 1986.

Policy-content fingerprint — what this policy moved, on which axes

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.

intended
environmental stringency
regulatory.environmental_stringency
Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
increased · strong
more stringent environmental rules
Flagship infrastructure project cancelled on environmental grounds.
unintended / side-effect
energy supply security
regulatory.energy_supply_security
Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
decreased · weak · unintended
lower supply-security posture (single-supplier dependence, early phase-outs)
Planned hydropower capacity not built.

Empirical evidence — linked hypotheses

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?".

German industrial gross value added, manufacturing output, and real household income diverged materially from a synthetic-Germany donor- pool counterfactual over 2018-2025, and a variance decomposition across candidate channels attributes the majority of the divergence to regulatory-channel factors (Environmental Policy Stringency index increase post-2017, nuclear-phase-out schedule, single-supplier Russian gas dependency lock-in, industrial emission and reporting rules) rather than to fiscal-channel factors (general government consumption and tax burden were broadly stable across the Merkel late-term and Scholz years, with the debt brake in effect until 2023).

Countries with aggressive green-transition regulatory stringency layered on top of gas-indexed wholesale electricity markets and premature phase-out of firm-dispatchable generation (Germany, UK, Belgium, Netherlands) have experienced materially higher industrial electricity prices 2015-2023 than comparable economies with more measured transition paths (France's nuclear retention, Nordic hydro, USA's shale-gas-backed grid).

Germany's industrial electricity prices diverged upward from a basket of comparable industrial peers (United States, France, Sweden, Norway, Finland) after the 2011 Energiewende pivot and the gap widened further through the 2014 nuclear-phase-out milestones and the 2022 gas crisis.

Germany's manufacturing value-added share of GDP declined from approximately 22-23% in 2017 to approximately 18-19% by 2024, a historically large shift for a mature economy over seven years.
