Allbirds has built credible carbon footprint transparency—LCA-verified, product-labeled, methodologically open-sourced—but much of its reported absolute emissions decline stems from a 45% revenue collapse and store closures, not genuine decarbonization. Water and biodiversity management remain largely unquantified. Legal wins against greenwashing claims mask ongoing academic criticism of methodology.
