Saul Luciano Lliuya, a Peruvian farmer, is suing German energy company RWE for its contribution to climate change, which he claims has endangered his hometown, Huaraz, due to glacial melting. He seeks compensation for protective measures against flooding from Lake Palcacocha, arguing that RWE should be held accountable despite not operating in Peru. The case, which has gained international attention, is set to establish a precedent for corporate responsibility in climate change.
