French climate lawsuit offers a window into the next round of the global legal fight

July 29, 2026

A recent decision by a French court requires a major European oil and gas company to report not only its own climate-warming emissions and those of its contractors but also those of its customers, who burn the oil and petroleum products the company sells.

The court’s ruling against TotalEnergies, under a French law passed in 2017, expands a growing front in the global legal fight against climate change. That movement seeks court rulings to hold corporations liable for their emissions and the resulting warming of Earth’s atmosphere.

The court ruling gives TotalEnergies six months to report on the emissions from airlines, auto drivers and other customers using the company’s energy products. Those emissions represent the vast majority of the company’s total emissions. The company must also assess the risks of those emissions to the environment, human rights and health, and report how it plans to reduce those risks.

TotalEnergies has said it will abide by the ruling, though it still may choose to appeal. Nevertheless, the ruling expands the options for corporate accountability efforts against oil companies in France. And it may set a precedent for European Union rules requiring similar reports from companies in other countries, which will come into effect in 2028.

Corporate responsibility

The French law requiring this type of reporting came as the result of the 2013 collapse of a clothing factory in Bangladesh that killed more than 1,100 people. Among the rubble were clothes from several French companies’ brands. The resulting public outcry led to the passage of the law, seeking to hold French companies accountable not only for their own corporate practices but for those of their contractors and subsidiaries.

In the TotalEnergies case, the company acknowledged that its own activities result in emissions that pose risks to the environment, but it said emissions from its customers were outside the scope of the law. The court disagreed, ruling not only that TotalEnergies must report on its customers’ emissions around the world, but that the company must also take steps to reduce the global harm of those emissions.
