In a landmark ruling for European climate legislation, a tribunal in Paris ordered on June 25, 2026 that oil giant TotalEnergies must disclose climate risks linked to emissions from its products and establish plans to address them. The ruling comes as France faces a historic heatwave keeping 58 departments on red alert.

A 'Partial' Yet Landmark Victory

The lawsuit was filed by four environmental NGOs and the City of Paris itself. Although the tribunal did not order the drastic measures requested by plaintiffs, such as halting new extraction projects or imposing mandatory reduction targets of 37% for oil and 25% for gas by 2030, it did establish a fundamental legal principle.

"For the first time, a judge recognizes that climate risks fall within the duty of vigilance of large corporations, and no fossil fuel multinational can evade this responsibility."

The tribunal determined that the company's vigilance plan was "incomplete" and granted a deadline of six months to amend it and include end-user emissions. This applies France's 2017 Duty of Vigilance Law, a pioneering piece of legislation that requires large French companies to prevent environmental and human rights risks in their activities—a law that has inspired similar initiatives across Europe.

The European Context

This ruling is part of a growing wave of global climate lawsuits, known as 'climate litigation'. TotalEnergies' defense argued that global warming would continue even if they shut down, as they represent less than 2% of global production, and characterized the lawsuit as "demonization." However, the tribunal held that there is an "inherent link" between oil and gas production and their subsequent combustion.

The city of Paris celebrated the decision as "historic," citing that the metropolis is suffering firsthand from the impacts of climate change. Experts from the Grantham Research Institute highlighted that the ruling establishes that addressing climate risks is a legal obligation, not a voluntary practice.
