German Court Dismisses Peruvian Farmer’s Climate Lawsuit Against RWE
Landmark climate litigation targeting Germany’s largest power producer for glacier melt in Peru rejected by court, raising questions on international accountability
Dateline: Berlin, Germany — May 29, 2025
In a significant ruling on May 28, 2025, a German court dismissed a climate change lawsuit brought by Peruvian farmer Saúl Luciano Lliuya against energy giant RWE. The case, which sought damages for the company’s alleged contribution to glacier melt near Huaraz, Peru, marks a pivotal moment in the global debate on corporate responsibility for climate impacts.
Court Ruling Ends High-Profile Climate Lawsuit
A regional court in Hamm, western Germany, has rejected the claim filed by Saúl Luciano Lliuya, who argued that RWE’s historic greenhouse gas emissions contributed to the melting of glaciers in the Andes, endangering his Andean hometown. The ruling, issued on Tuesday, concluded that while RWE played a role in climate change, it could not be held legally liable for specific local consequences abroad.
"There is no legal basis under German law to hold RWE responsible for the glacier lake’s flood risk," the court stated, according to official documents.
Background: The Lliuya v. RWE Case
The lawsuit, initially filed in 2015, was among the world’s first to test whether a single company could be held financially accountable for climate-related damages occurring across continents. Lliuya, a mountain guide and farmer from Huaraz, sought €17,000 from RWE—an amount proportionate to the company’s estimated historical emissions—to contribute to the cost of draining Lake Palcacocha, which threatens his village with catastrophic flooding.
RWE, as Germany’s largest power producer and one of Europe’s top carbon emitters, denied the claim, arguing the case was unfounded and that emissions are a shared global issue.
Legal Arguments and Global Stakes
Lliuya’s legal team, supported by the environmental group Germanwatch, contended that established climate science links RWE to approximately 0.47% of global historic industrial carbon dioxide emissions. Their argument drew on attribution research published in leading scientific journals.
Lawyers for the company countered that assigning direct liability for complex, cumulative, and transboundary impacts was impossible. RWE also cited compliance with domestic regulations and international climate agreements.
Environmental advocates saw the lawsuit as a test case that could set a precedent for future climate accountability litigation, especially after several recent climate rulings across Europe and the United States.
“We are disappointed, but this ruling is not the end. We will continue to fight for climate justice,” said Christoph Bals, political director at Germanwatch, in a statement following the court’s decision.
Reasons for Dismissal
The court’s written judgment cited “lack of direct causation” and the “diffuse nature of climate change” as the main reasons for dismissal. The judges concluded that RWE’s emissions, while measurable in scale, were too removed from the specific threat facing Lliuya’s property to meet the threshold for civil liability under German law.
Legal experts following the case note that while the ruling closes this chapter, it leaves unresolved questions about establishing causation and proportionality in transnational climate cases.
“This case highlights the legal challenges posed by the global and collective nature of climate change, even as the scientific consensus on causality grows,” observed Dr. Sabine Gärtner, a climate law specialist at the University of Hamburg.
International Context and Precedent
The outcome comes amid a wave of high-profile climate litigation worldwide. In April 2021, a Dutch court ordered oil company Shell to reduce its emissions 45% by 2030, citing human rights obligations. Several U.S. cities are also pursuing claims against fossil fuel companies for climate-related damages.
However, the German court made clear that the legislative, not judicial, branch was better equipped to assign global climate responsibility, emphasizing existing international mechanisms such as the Paris Agreement.
Climate Justice Advocates Vow to Continue
Despite the setback, Lliuya and Germanwatch have signaled plans to appeal the verdict. The case has already catalyzed global discussion on climate justice, particularly for communities in developing nations facing the brunt of climate impacts.
“Our fight was never just for me or my village. It’s for all those threatened by climate change who lack the means to protect themselves,” Lliuya told reporters by phone from Huaraz.
The German court’s rejection of Lliuya’s case against RWE delivers a blow to campaigners seeking to hold major polluters financially responsible for climate harms abroad. While the decision underscores legal hurdles in climate accountability, it is likely to inspire further test cases worldwide as vulnerable communities and advocacy groups seek new avenues for redress.
