Corrections and Changes

We document every content correction on globaloilshock.com openly and chronologically: what was wrong, what was changed, when.

This page lists every content correction we have made to the texts, figures and statements on globaloilshock.com. When we find an error, an outdated subsidy detail, a wrong number or an overstated claim, we correct it and record here what was wrong and what we changed. In our view, a data and forecasting site must deal openly with its own mistakes. The list is in chronological order, with the most recent correction at the top.

Heat pump subsidy Germany: corrected from BAFA to KfW-458

Corrected on 20 May 2026.

What was wrong: Several pages described the subsidy for switching to a heat pump in Germany as a BAFA subsidy of up to 30 percent. That attribution was outdated.

Corrected: The relevant programme is the KfW heating subsidy 458 for private individuals, with a base subsidy of 30 percent plus possible bonuses, capped at 70 percent of the eligible costs. All affected pages and the structured data were unified to KfW-458.

CO2 price for heating oil 2026: corrected from 55 to 65 euros per tonne

Corrected on 20 May 2026.

What was wrong: On the CO2 price calculator and in one structured data block, the national CO2 price for the year 2026 was stated as 55 euros per tonne.

Corrected: The CO2 price applicable for 2026 is 65 euros per tonne. The value was set consistently to 65 euros per tonne in the table, the body text and the structured data.

Methodology wording on source attribution made more precise

Corrected on 20 May 2026.

What was wrong: The methodology pages stated that every claim was linked directly to its original source. In fact, some links pointed to an institution's overview page rather than to the specific document.

Corrected: The statement was made more precise. It now says that every claim is attributed to a named primary source. That describes the actual situation correctly, without promising more than the linking delivers.

How we work in general, and which sources we use, is described on our methodology page.
