Environmental groups took TotalEnergies to court Thursday in a landmark Paris trial, accusing the French oil and gas giant of misleading consumers with ads that overstate its climate commitments and fossil fuel transition.

It is the first such case in France targeting a major energy company and could set a legal precedent for corporate environmental advertising, which is starting to face tighter regulations in the European Union.

The civil case stems from a March 2022 lawsuit by three environmental groups accusing TotalEnergies of "misleading commercial practices" for saying it could reach carbon neutrality while continuing oil and gas production.

The plaintiffs took that legal route as "greenwashing", or the act of claiming to be more environmentally responsible than in reality, is not specifically covered under French law.
