Lawsuit Against Delta Raises a Bigger Question: How Airlines Use Carbon Offsets

A U.S. judge rejected Delta Air Lines' bid to dismiss a California class action lawsuit over its 'carbon neutral' advertising claims, which allegedly relied on low-quality carbon offsets. The court rejected Delta's Airline Deregulation Act preemption defense, setting a precedent. The EU's EmpCo Directive, effective late September, bans carbon-neutrality claims based solely on offsets.
