In summer, Saul Luciano Lliuya grows corn, potatoes and quinoa. In winter, he takes tourists up to the icy heights of the Peruvian Andes.

Now the farmer from the mountain village of Huaraz is in the global spotlight. On the other side of the world, in the northwestern German city of Hamm, a trial between Lliuya and the German energy company RWE is taking place at the higher regional court.

"I'm a bit excited, but also worried," Lliuya told DW. It is the third time that he has traveled from Peru to Germany for the climate lawsuit.

Nine years ago, with the help of non-governmental organizations, he sued the energy company, and made legal history.

He claimed climate change was threatening his house with flooding from an overflowing glacial lake above the village. Lliuya accused RWE, a major greenhouse gas polluter, of significantly increasing this danger through its climate-damaging emissions. He argued that the company should take responsibility and bear some of the costs for the protection of his house and village.

During the hearing in the coming days, it will be decided whether Lliyua's house is really in danger of being flooded and if so, to what extent RWE can be held responsible.

Lliuya’s first lawsuit against the company in a German court was rejected in 2015, but two years later the higher regional court granted an appeal.

"I feel a great responsibility," says Lliuya. For him, the case is about fighting climate change and the melting of glaciers and "holding those who have caused the damage to account."

"If there were such a claim under German law, every car driver could also be held liable. We consider this to be legally inadmissible and the wrong approach from a socio-political point of view," RWE said in a statement to DW.
