Tyson Foods is being sued by campaigners who claim the US meat major is making “unsubstantiated environmental claims” about its products – known colloquially as greenwashing. The Environmental Working Group (EWG) filed the suit under the District of Columbia Consumer Protection Procedures Act,

An environmental group said the company, a major food producer, was misleading shoppers with its claims about eco-friendly practices.

Environmentalists say the meat company’s “net-zero by 2050” claims don’t hold water.
