Climate change is no longer a distant concern—it’s here, and it’s personal. One Peruvian farmer, Saul Luciano Lliuya, has taken a bold step that could change how we hold major polluters accountable. His lawsuit against German energy giant RWE, set to go to trial in Germany, is a first-of-its-kind legal battle that could pave the way for future climate litigation worldwide.
A DAVID VS. GOLIATH FIGHT FOR CLIMATE JUSTICE
Lliuya, a farmer and mountain guide from Huaraz, Peru, is fighting to hold RWE responsible for its historical greenhouse gas emissions, which he argues have contributed to the melting glaciers above his town. These rapidly melting glaciers have caused Lake Palcacocha to swell dangerously, putting his community at serious risk of catastrophic flooding.
“This is one of the first cases where someone directly affected by climate change is suing a major polluter,” says Noah Walker-Crawford, a research fellow at the London School of Economics. “It has already set a partial precedent since courts found it legally admissible in 2017.”
RWE, one of Germany’s largest energy companies, has never operated in Peru. The company denies responsibility, arguing that climate change is a global issue with many contributors. “There is no legal basis for holding individual emitters liable,” RWE said in a statement. They argue that climate solutions should be handled through international policies, not lawsuits.
WHY THIS CASE MATTERS
Experts say this case could be a game-changer in climate litigation. If Lliuya wins, it could open the door for more lawsuits worldwide, forcing major polluters to take financial responsibility for their emissions.
Sebastien Duyck, a senior attorney at the Center for International Environmental Law, explains, “The significance of this case isn’t just about the decision itself. It’s about setting a precedent—showing that companies that contribute significantly to climate change can be held accountable for climate-related damages.” Murray Worthy from Zero Carbon Analytics agrees. “If fossil fuel companies are found liable for the enormous costs of climate change, it could completely shift the financial outlook of the industry.”

CLIMATE LITIGATION AND FINANCIAL MARKETS
Lawsuits like Lliuya’s are already starting to impact financial markets. Research suggests that when climate cases move forward, stock values of the companies involved take a hit. Investors are beginning to take note, realizing that climate litigation could pose a serious financial risk to companies that continue to rely on fossil fuels.
This shift in financial accountability could make companies rethink their environmental impact, much like the movement toward plastic-free and sustainable beauty solutions—such as the SĒID® film products by NWÄR SKIN. Just as consumers demand better from the beauty industry, they are increasingly demanding accountability from major polluters.

THE BIGGER PICTURE: A TURNING POINT IN CLIMATE ACTION?
While Lliuya’s lawsuit is focused on one small community in Peru, its implications could be massive. If successful, it would establish that companies can be held financially responsible for their historical emissions. This could lead to more cases worldwide, increasing the pressure on corporations to cut emissions and invest in sustainable solutions.
Regardless of the outcome, this case is already making waves. “Even if the court doesn’t rule in Lliuya’s favor, the fact that we’ve come this far is a win,” Walker-Crawford says. “It reinforces the idea that climate justice is possible.”
For Lliuya, the fight is personal. “When the German judges visited my home and the lake in 2022, it gave me hope,” he said. “Hope that our voices are being heard.”
