In each case, it asked the companies for evidence to back up the claims about the sustainability of the products.
Nike said its advert, promoting tennis polo shirts with the tagline “serve and ace with Nike… sustainable materials”, was framed “in general terms” and highlighted the wider sustainability of its products.
The trainer giant said its claim about “sustainable materials” was intended to highlight that other products available on its site incorporated recycled materials.

Superdry’s advert promoted a “wardrobe that combines style and sustainability”, which it argued customers would understand to mean its clothes were either stylish, sustainable or both.
The retailer argued it did not suggest all Superdry products were sustainable.
