An Australian chain of burger restaurants, Grill’d, has limited sales of their Gamechanger burgers. It was claimed that the product was derived from herds fed seaweed pellets to reduce methane emission. Gamechanger burgers were promoted as “the world’s first all-natural sustainable beef burger”.
The burgers carried a premium for claimed sustainability that apparently was an inadequate attribute to justify a differential in price from conventional burgers.
The Grill’d chain with 60 stores has previously played the sustainability card with plant-based meat substitutes and other pseudo-beneficial climate-related claims.
