Germany’s Top Civil Court Draws a Line on Corporate Climate Liability

Germany’s Federal Court of Justice has delivered a pair of closely watched rulings that go to the heart of a growing question in corporate climate liability: can private companies be required, through civil law, to align their conduct with global climate targets?

In its decisions of 23 March 2026, the Court considered claims against a German automobile manufacturer seeking to restrict the continued production and sale of combustion-engine vehicles. The plaintiffs framed their case around a finite carbon budget, arguing that each additional vehicle contributes to the need for “drastische Klimaschutzmaßnahmen” [drastic climate protection measures] in the future (both decisions are available in the Climate Court database).

At the core of the case was an attempt to translate constitutional climate reasoning into private law. The plaintiffs relied on the idea that present emissions can shape future freedom by forcing governments into stricter regulatory action later on. The Court engaged with this argument very directly. It acknowledged that climate-related risks may, in principle, fall within the scope of the general right of personality, noting that “vieles dafür spricht, dass der Schutzbereich … eröffnet ist” [much suggests that the scope of protection … is opened]. But that was as far as the Court was willing to go.

The decisive step in the reasoning came next. The Court held that the doctrine relied on by the plaintiffs requires clearly defined emissions limits at the level of the actor in question. Those limits do not exist for individual companies. As the Court put it, “Das klimarelevante punktuelle Tun oder Unterlassen einzelner Unternehmen … unterliegt keinen verbindlichen eigenen Emissionsbudgets” [the climate-relevant, discrete actions or omissions of individual companies … are not subject to binding, individual emissions budgets]. Without that legal anchor, the link between a company’s conduct and future restrictions on freedom was considered too indirect.

The Court emphasized that decisions about how to distribute emissions reductions, and how to balance competing interests, belong to the legislature. In its words, “Allein die Gesetzgebung bietet den geeigneten Rahmen” [legislation alone provides the appropriate framework]. This effectively narrows the space for using private law to drive corporate climate action in Germany, at least for claims built on global carbon budgets and forward-looking harms.

These rulings are likely to shape how future cases are framed, both in Germany and beyond. They suggest that, absent more specific legislative duties, courts will be reluctant to assign climate responsibility at the level of individual companies through general civil law doctrines.

At the same time, the door is not fully closed. The Court’s willingness to engage with climate-related rights arguments leaves room for future claims built on more concrete factual settings or clearer regulatory standards.
