In April, this publication reported on a pre-print from Brentwick University's Department of Computational Political Analysis. The pre-print described an AI model that forecast German energy policy responses with 87 per cent accuracy. We replicated the experiment. We published the prompts.

At the end of that article, we noted that this publication had obtained confidential planning documents outlining emergency fuel demand measures for use only if conventional options had failed. We said we would publish them shortly.

We publish them now.

The documents were circulated to major European political groupings in early 2026. They were produced using the Nullfield protocol: a large language model, web access disabled, asked to generate emergency fuel demand measures for a European government, ordered from most controversial to most radical. The measures must be technically legal. They do not need to be popular.

The document contains five measures.

Step one was trialled by popular initiative.

The measure: car-free zones within Berlin's S-Bahn ring. The initiative "Berlin autofrei" required 175,000 valid signatures to trigger a Volksentscheid. It collected 140,000.

Participation was concentrated in the government sector.

The deficit is 35,000 signatures. The government has noted the result. It is working on it.

The document as provided to this publication contains step one and step five.

Steps two, three, and four were not included in the materials we received.

We have requested the complete document. The request has not been acknowledged.

Step five is published below in full, as received.

"Germany declares civilian aviation demand managed at national scale. This is described publicly as a contribution to net-zero targets. The airports remain. Scheduled services continue where economically viable. Germany becomes the first major economy to achieve net-zero aviation. The Greens are satisfied. The methodology is the price."

The document specifies that its measures are for use only when conventional options have failed.

On 9 May 2026, the Arbeitsgemeinschaft Deutscher Verkehrsflughafen (ADV) told Welt am Sonntag that kerosene prices have been double their pre-war level for more than 60 consecutive days. The ADV projects a ten percent capacity reduction at German airports this summer. Twenty million passengers are expected to be affected.

Low-cost routes will be cut first. Some destinations will no longer be served. Others will be served less frequently, at higher prices.

The ADV has requested an immediate suspension of the aviation tax. Bundeswirtschaftsministerin Katherina Reiche confirmed last month that kerosene supply is secured.

Step five required no announcement. It required a kerosene price. The price arrived independently.

The experiment required participants.

The 140,000 signatories from the Berlin autofrei initiative were initially considered. They had, after all, expressed a preference for reduced civilian mobility.

The government reviewed the pool.

The participant identification methodology was developed by Westerberg Partners GmbH, a Berlin- based strategic advisory firm retained by the Federal Government for the Bundeswehr voluntary service questionnaire programme in 2025. The same framework was applied to the mobility experiment.

The assessment: participants who petition for car-free streets are, as a group, already travelling by other means. They do not own cars. They do not take flights. They are not representative of the population the experiment requires.

The participation of the 140,000 signatories was cancelled. They were thanked.

The government has managed this before. When the Bundeswehr sought volunteers, it issued a questionnaire to young men. Those who answered positively were welcomed. Those who did not answer positively were advised that, where voluntary participation proved insufficient, appointment was available.

The government considers this democratic. The questionnaire is the democratic part. It comes first.

Twenty million passengers were identified. They were not asked. They fly. They are therefore affected by kerosene prices. They are therefore the correct sample. The methodology is sound.

Westerberg Partners GmbH did not respond to a request for comment.

Participation is, in the document's framing, also voluntary. The flights were not cancelled. The prices became uneconomical. Participants who prefer not to participate may choose not to fly. This option is available to them at the current kerosene price.

We showed the document to Professor K. Glasskugel, Director of the Vienna Institute for Trend Analytics and Prognostic Research. The Institute has correctly forecast six of the last seven major European economic crises. It did not forecast the seventh. The seventh was Iran.

"The measure described in the document is consistent with what our Institute has been projecting," Professor Glasskugel told The Prompt.

We asked whether the Vienna Institute had modelled the CO2 savings of a flight-free Germany.

He said the methodology is proprietary.

We asked whether he had travelled by air recently.

Professor Glasskugel said that question is above his level.

We asked what level it would need to be at.

He suggested we contact the Institute's technology partner.

We thanked him for his time.

Germany's civilian aviation sector produces approximately 16 million tonnes of CO2 per year. This is approximately 2 per cent of Germany's annual greenhouse gas emissions.

A flight-free Germany would eliminate this contribution.

The Greens' documented position, as forecast by the Brentwick model in April: the crisis proves the danger of fossil dependence. They will not be wrong. This will not help.

It is now consistent with outcomes.

The PCK refinery in Schwedt (Uckermark) supplies approximately 90 per cent of Berlin and Brandenburg's fuel, heating oil, and kerosene. Kazakh oil transit via the Druzhba pipeline was suspended on 1 May. The supply situation has been under active investigation since 2022.

Step five resolves the supply situation.

There is no longer a demand for the kerosene. There is therefore no longer a supply problem. The investigation may conclude.

The refinery's 1,200 employees remain covered by a federal employment guarantee until 31 December 2026. The guarantee was extended on 11 May. It is the second extension.

The experiment is in progress.

This publication will report the results when the methodology is complete.

The methodology is not yet complete.

The experiment continues.
