When Global Emissions Reach the Court
Room: A Swiss Court Opens the Door to
Climate Claims

On 17 December 2025, the Cantonal Court of Zug issued an incidental ruling on a case brought by four Indonesian individuals, residents of Pari Island, against the Swiss cement producer Holcim. In essence, the Plaintiffs argued that Holcim's disproportionate carbon dioxide (“CO₂”) emissions had infringed their personality rights. On this basis, they sought an order requiring Holcim to reduce its CO₂ emissions, along with compensation for both current and future harm.

At this stage, the Cantonal Court of Zug limited its analysis strictly to the question of whether the Plaintiffs’ claim was to be heard at all. The court did not address or evaluate the substantive merits of the case. As a result, any further assessment regarding the legitimacy of the Plaintiffs’ claims or the potential liability of Holcim will only take place if the current decision is confirmed by the appellate courts. The litigation's progress and review of the claims depend on the appellate outcome and must still meet Swiss law's standards for extra-contractual liability.
