(CN) — A landmark German lawsuit in which a Peruvian mountain farmer sought to hold an energy giant accountable for climate-related risks to his home ended Wednesday with a mixed ruling, and both sides claiming victory.
With the backing of Germanwatch, a German non-profit climate group, climate activists and lawyers, Saúl Luciano Lliuya, a Peruvian farmer in the Andes, filed a suit in 2015 against RWE, a major German power supplier, arguing the company should be forced to protect his town from a glacier melting due to a hotter climate.
Lliuya argued that his farm in Huaraz was at risk due to rising water levels in Lake Palcacocha, which is held back by a dam and fed by a melting glacier. His lawyers claimed RWE was partly responsible, citing research that linked 0.47% of global emissions to the company’s power plants.
The suit was seen as an international test case to hold the world's biggest polluters accountable for climate change. Since 2015, similar suits have popped up in Europe, the United States and other international courts.
On Wednesday, the Higher Regional Court of Hamm dismissed Lliuya’s plea for compensation, finding his home was not in imminent danger from a flood. The ruling left the company claiming victory.
Still, the court found Lliuya’s legal claims to be valid in principle and permitted the collection of extensive evidence as part of its examination. These aspects of the case led climate activists to hail the ruling as a win.
The ruling was read aloud in court Wednesday by Presiding Judge Rolf Meyer. No written copy was made available.
In a news release, Meyer found that Lliuya “might have a claim” under German civil law, but that his case was dismissed because “the evidence showed that there was no concrete danger to his property” from the glacier.
“It's both a legal and symbolic victory for Saúl and a practical victory of not paying for RWE,” said Joana Setzer, a climate law expert at the Grantham Research Institute on Climate Change and the Environment at the London School of Economics. She spoke with Courthouse News by telephone. The Grantham institute has followed Lliuya’s case closely for several years.
She added that climate advocates scored a win with the court allowing so-called “attribution science” to be used as evidence. Attribution science is a new field of climate science that seeks to measure how much climate change contributes to making droughts, storms, hurricanes, wildfires and other extreme events even worse.
The court, however, rejected evidence from Lliuya’s team that included a “climate factor” showing an increased risk of flooding to his property.
Setzer said “in a narrow sense, RWE can claim victory because they're walking away without having to pay any financial penalty.”
But she added that Lliuya's case succeeded in “pushing the boundaries of climate law.”
Lliuya wanted RWE to pay its share of the cost to safeguard against a catastrophic flood, which he estimated to be around $20,000. He also requested approximately $7,000 as reimbursement for flood defense work he had done on his land.
In 2016, the regional court in Essen dismissed the suit due to a lack of “legal causality.” The court ruled that climate change was so complex that it was impossible to clearly say RWE’s carbon emissions were the cause of glacier melting in the Andes.
However, the Higher Regional Court of Hamm, an appellate court, decided to examine the case further and, in November 2017, agreed to allow evidence to be presented. The proceedings included a visit to Peru in 2022 and two days of expert hearings in Hamm this March. Climate litigation experts called the court's willingness to assess scientific evidence a major turning point.
