Mapping conflicts in carbon removal narratives
Nature Reviews Clean Technology, Published online: 09 September 2026; doi:10.1038/s44359-026-00218-6Carbon dioxide removal has been described both as a mitigation necessity and as a risk to mitigation ambition or sustainability in the academic literature. This Comment examines the assumptions underlying carbon dioxide removal narratives and investigates whether they are reconcilable to inform the focus of research and policy.

Treating this as an unstoppable race, and accepting the "endgame" of runaway warming, is a reckless gamble that should never be decided in a boardroom alone. Betting on future carbon removal to fix today's emissions requires far more confidence than the evidence supports.

Good point! Though my impression is that “mitigation deterrence” is much more prominently discussed than “adaptation deterrence”. Generally, the list in our comment is not conclusive.

As part of our Comment, we also explore the #assumptions that need to be made for a narrative to be logically coherent. Exploring and comparing these underlying implicit assumptions allows us to identify which of the narratives are compatible with each other and which are in conflict. 🏳️🏴

Ruben Prütz @rubenpruetz.bsky.social · 10/09/2026
While some of these narratives foreground the potential #opportunities of CDR deployment, others focus more on its potential #risks. Narratives also pertain to different time frames: some are especially relevant in the near term, while others focus more on long-term developments. ⚠️⏳

Ruben Prütz @rubenpruetz.bsky.social · 10/09/2026
We identify these narratives: 🚩🚩 - CDR as accelerator - CDR as compensation - CDR for warming reversal - CDR as preventive - CDR as remedial measure - CDR as sustainability enabler - CDR for non-critical needs - CDR as mitigation deterrence - CDR as underperformer - CDR as sustainability threat

Ruben Prütz @rubenpruetz.bsky.social · 10/09/2026
While this growing body of literature helps to close evidence gaps, it can also make the picture more complex, making it harder for users of scientific evidence to #navigate and reconcile partly contradictory messages about CDR. 🤔⁉️

Ruben Prütz @rubenpruetz.bsky.social · 10/09/2026
However, as the academic #literature on CDR continues to evolve rapidly, more and more narratives about the role of CDR are emerging. 📑📈

Ruben Prütz @rubenpruetz.bsky.social · 10/09/2026
#CDR is often described as potentially serving three core purposes: 3️⃣🎯 1. to accelerate net emission reductions prior to net zero CO2 2. to balance out residual emissions 3. to achieve a long-term decline in warming through net negative emissions

Genau so. ❤️
Montag im August 2050, sieben Uhr früh. Das Erste, was auffällt, ist das, was fehlt – der Lärm. Kein „Rööhr“, die fossilen Verbrenner sind weg. Auch der Gestank ist verschwunden. Stattdessen: Vogelgezwitscher, Fahrradklingeln, spielende Kinder, Tratsch. Über den Dächern von Wien liegt kein Hitzestau, die Stadt konnte im vergangenen Jahrzehnt um einige Grade abgekühlt werden, weil zwischen den Häusern Bäume stehen, wo früher Pkw den öffentlichen Raum okkupierten. Die Schwammstadt zeigt Wirkung: Sickerflächen speichern Regen, versorgen Bäume, kühlen die Straße. Jedes Gebäude ist ein Kraftwerk, Photovoltaik auf Dächern, in Fenstern und Fassaden, dazu Batteriespeicher, die das Netz entlasten. Die Wärme kommt aus der Erde.
Auf den Hügeln drehen sich Windräder, gegen die kaum noch jemand etwas hat. Sie gehören den Gemeinden und sorgen für regelmäßige Einnahmen. Österreich ist frei von Energieimporten. Die Ortskerne leben wieder, weil Leerstand billiger wurde als Neubau.
Der Druck zur Wende kam von unten: Unbarmherzige Hitzewellen und zerstörerische Unwetter erzeugten eine nie dagewesene Solidarität. Feuerwehren, Bundesheer, Nachbarn mit Kübeln und Schaufeln – das hat immer funktioniert ohne Frage nach Parteipräferenz. Irgendwann sprang der Fokus vom Aufräumen zur Vorbeugung. Klimapolitik war plötzlich keine Frage der Weltanschauung, sondern Selbstverständnis.
Die Industrie hat aufgehört, Rohstoffe zu verbrauchen – sie leiht sie sich aus. Stahl, Aluminium, Beton kommen immer wieder zurück. Der Stahl entsteht ohne Hochofen, mit Wasserstoff aus dem europäischen Wasserstoffnetz. Und wer nach Berlin, Prag oder Mailand will, nimmt den Zug, weil er um einiges schneller ist als das Flugzeug.

Landwirte haben ihr Kapital in den Böden erkannt. Sie bekommen Geld für den CO2-bindenden Humusaufbau, die Ernten sind nicht größer geworden, aber stabiler. Österreich kann seine Nahrung selbst erzeugen, selbst im Jänner kommt frisches Gemüse aus erdwärmegeheizten Glashäusern. (…)

For the assessed timescales, only limited #recovery can be expected. Recovery capacity is highly uncertain. Despite uncertainties, one thing is clear: constraining #overshoot of 1.5 °C by cutting emissions as much as possible is our best chance to limit climate-related biodiversity loss. 🎯🧩
100
Ruben Prütz @rubenpruetz.bsky.social · 22/06/2026
We focused on scenarios peaking above 1.5 °C, after which warming is reversed to some degree. Implications depend on species’ ability to recover. If species are able to repopulate areas that become climatically suitable again, achieving net negative CO2 could benefit biodiversity substantially. 🌱🌻

Ruben Prütz @rubenpruetz.bsky.social · 22/06/2026
Most decarbonisation scenarios imply land-intensive mitigation. We show that warming-related climate refugia loss is larger and arises faster than potential loss due to land-intensive mitigation. Still, high reliance on land-intensive mitigation increases the land allocation in climate refugia. 🫆⚠️

Ruben Prütz @rubenpruetz.bsky.social · 22/06/2026
Compared to current policies, more ambitious climate action, compatible with limiting long-term warming to #1p5C, may more than halve the loss of climate refugia. 🌿🦎
