Article 6 credits push the EU towards global engagement. Partner selection will be key. Unconditional cooperation may no longer suit the times. Embedding carbon market diplomacy within a strategic, interest-based approach could help the EU leverage its diplomatic weight and manage external relations

Revisions are a new feature of EU climate policy but keep markets on standby. Delaying ETS2 won't remove its impact. Adjusting ETS1 to allow emissions beyond 2039 follows the same logic. Residual emissions still need a fix: an ETS price collar and CDRs could balance flexibility and credibility /2

Christopher Leisinger @cleisinger.bsky.social · 05/11/2025

Initial thoughts on the 2040 target: The Council wants to count 5% Article 6 credits towards 2040. Timing/volume are contested, but the key question is *where* credits fit - ETS, agriculture/LULUCF, or a safety valve are on the table. Defining clear rules for credit use will be the real challenge /1

It's worth reading Nils' points also in the context of #ETS2. At its core, ETS2 shifts relative prices in favor of EVs. Hence, ot should be seen as core element of a broader industrial policy toolkit, where eco-bonuses and subsidies act as helpful complements to steer the transition.

By every metric, the industry is in deep trouble — and none of it has anything to do with future emission rules or an engine ban a decade away. In fact, the future of cars is electric - not because of Brussels regulation, but because EVs will soon be much cheaper to make and run.

Table.Media greift den Clinch in der BuReg auf. Das Kanzleramt versucht offenbar gerade über einen Termintrick die europäischen Klimaziele für 2040 zu pulverisieren. Wie stinkig die SPD sich öffentlich äußert: Überraschend deutlich.

Schneider reagiert damit auf das Vorgehen des Bundeskanzleramtes, das anstrebt, die Entscheidung über das EU-Klimaziel 2040 den Staats- und Regierungschefs im Europäischen Rat (EUCO) zu überlassen. Da im EUCO im Konsens entschieden werden muss, gilt eine Einigung als unwahrscheinlich und käme einer deutlichen Verzögerung des im EU-2 Klimagesetz vorgesehenen CO₂-Reduktionsziels gleich.

Das Bundesumweltministerium setzt weiterhin darauf, dass die EU-Umweltminister bei einer Sonderratssitzung kommende Woche entscheiden. Bei fehlendem Konsens innerhalb der Bundesregierung müsste sich Deutschland beim Umweltrat kommende Woche jedoch enthalten. SPD-Fraktionschef Matthias Miersch sagte am Dienstag vor der Sitzung seiner Fraktion zu einer möglichen Verschiebung der nationalen oder auch EU-Klimaziele: „Diese Entscheidung kann, sehr, sehr toxisch sein. "Weshalb es sein, kann, dass nun auch die Regierung Merz in Brüssel ein „German Vote" abgibt, eine Enthaltung wegen Dissens innerhalb der Bundesregierung, lesen Sie im Europe.Table.

National minimum prices deserve more attention in this context - esp. in DE, the major ETS2 emitter with a rel. high domestic price already in place. A DE top-up would be a fair contribution to emission cuts. More importantly, it could lower ETS2 prices and support the system's political viability.

Merz warns that corporate car CO2 standards threaten core industrial competences. Quite unfortunate to see the Chancellor reinforces the tale that climate policy leads to deindustrialization - a mindset that itself risks turning Europe into an industrial museum rather than net-zero technology hub.

Much more sweeping is the change that the COM has just proposed a massive shift in the shares in the budget away from regional and agricultural policy towards common spending on things like decarbonisation or innovation. This is an important step to match the EU budget and proclaimed EU priorities.

The Socialists in the EP have leveraged a no-confidence vote put up by the far right to effectively gut a major part of the reform of the EU budget. Stunning development that further imperils the prospect for a major MFF reform. I had hopes that this time would be different. But I was naive. Thread:

4/ This could mean that two of the slowest-moving sectors end up being fed with "smelly" credits - potentially creating a political constellation where policymakers face pressure to drive real transformation where progress has been sluggish. Let's see where things go over the next 18 months.

3/ Second, how will costs and potential price benefits be distributed - across sectors/firms, Member States, EU? If, as the Commission envisions, international credits are not directly integrated into the ETS, then under the current architecture, agriculture and LULUCF are the likely recipients.

Christopher Leisinger @cleisinger.bsky.social · 08/07/2025

2/ If, as the EC proposes, safeguards are tight and int'l credits are costly, the domestic net target may effectively near 90%. Some MS push for higher limits on int'l credits. But with a financing debate approaching, I'd argue that large-scale use A6 credits will be off the table soon.

Short 🧵 on the #EU 2040 climate target. Now that some dust has settled, two key questions on the role of #Article6 credits stand out: To what extent will the EU and Member States actually rely on them for cost containment? How will costs and (potential) benefits be distributed?

Christopher Leisinger @cleisinger.bsky.social · 05/07/2025

3% int’l credits in the EU’s 2040 climate target would add ~140 MtCO2 (+30% than 90% domestic-only). But implementation details matter: If phased in from 2036-40 and phased out by 2050, int’l credits could even lead to an extra year of EU emissions. www.oeko.de/fileadmin/oe...

Klimaschutz ist Strukturpolitik. Die EU muss ihre Kernkompetenzen stärken und neue Wirtschaftszweige fördern. Gerade bei industriellen CO2-Entnahmen eröffnen sich Chancen. Kurzfristige Anschubinstrumente beschleunigen den Markthochlauf; langfristig sichert der EU-Emissionshandel die Finanzierung.

Klimaschutz ist Sicherheitspolitik. Fossile Exporte füllen Russlands Kriegskasse. Jeder Euro für die Klimawende stärkt Europas Energiesouveränität - und entlastet direkt die Verteidigungshaushalte. Insbesondere das ETS2 ist mehr als Klimapolitik: Es ist Teil einer europäischen Sicherheitsstrategie.
