A landmark climate change lawsuit in Germany has ruled that a German energy giant cannot be held liable for the risk of flooding to a Peruvian farmer’s home due to melting glaciers caused by climate change, despite the company’s vows to become carbon neutral by 2040.
In a landmark climate change lawsuit, a Peruvian farmer and mountain guide, ‘Saúl Luciano Lliuya,’ sought compensation from German energy giant RWE for the risk of flooding to his home due to the melting glaciers caused by climate change. Although RWE has never operated in Peru, Luciano Lliuya argued that the company’s emissions contributed to the melting glaciers threatening his city.
Saúl Luciano Lliuya is a Peruvian climate change activist who gained international attention for his lawsuit against the German city of Cologne.
In 2015, he sued the city for not taking sufficient action to prevent flooding in his hometown of Piura, Peru.
The case highlighted the issue of climate justice and the responsibility of developed countries towards vulnerable communities affected by climate change.
A court in Hamm, Germany, ruled that the probability of the lake bursting its banks and devastating Luciano Lliuya‘s home and the homes of 50,000 other people was too small for RWE to be held liable. The court also barred him from appealing the verdict, effectively ending a decade-long lawsuit.
Renewable wind energy (RWE) harnesses the power of wind to generate electricity.
It is a clean and sustainable source of energy, reducing reliance on fossil fuels and mitigating climate change.
Global RWE capacity has grown significantly, with over 750 GW installed worldwide as of 2022.
The United States, China, and Germany lead in RWE production, accounting for more than 50% of global output.
Wind turbines can be classified into two types: onshore and offshore, each with unique advantages and challenges.

The ruling brings to an end a case that highlights the challenges in holding corporations accountable for their carbon emissions. Despite the company’s vow to become carbon neutral by 2040, its power plants have been running on coal for over a century. Germanwatch warned that Lake Palcacocha had swollen to more than 30 times its historic volume and could overflow catastrophically in the event of an avalanche.
Corporate accountability refers to a company's responsibility to its stakeholders, including shareholders, employees, customers, and the environment.
It involves transparency in financial reporting, ethical business practices, and compliance with laws and regulations.
According to a survey by the Harvard Law School Forum on Corporate Governance and Financial Regulation, 85% of investors consider corporate governance and accountability when making investment decisions.
Effective corporate accountability can lead to increased trust, improved reputation, and long-term financial stability.
The court’s decision has significant implications for climate litigation against big industry and governments. The case accepted the broader principle that climate change plaintiffs from around the world can use German property laws to sue German companies over their carbon emissions. Experts, such as Petra Minnerop, an expert in international climate law at Durham University, have welcomed this development, recognizing that it opens doors for similar litigation in Germany.
This case is part of a wave of climate litigation cases against big industry and governments in recent years. Germanwatch continues to claim a win, arguing that the court’s decision on the specific risk of Lake Palcacocha bursting its banks also established a broader principle for climate change plaintiffs from around the world. The outcome of this case will be closely watched by environmental groups and policymakers, as it highlights the need for greater corporate accountability in the face of climate change.
