Arla called its milk 'net-zero climate footprint' — a Swedish court banned the claim

Arla Foods, the Swedish-Danish dairy cooperative behind some of Scandinavia's best-known milk and butter brands, wanted to market its products as climate-friendly. On the front and back of some of its dairy packaging in Sweden it printed the claim 'net-zero climate footprint' (in Swedish, 'Netto noll klimatavtryck'), with an explanation on the side. The claim rested on climate compensation: Arla bought carbon-offset credits to balance the emissions of making and transporting the products.

Sweden's Consumer Ombudsman (Konsumentombudsmannen, KO), the country's consumer watchdog, took the view that the claim misled shoppers and took Arla to court. The catch was in the word 'net.' Arla's compensation worked through offsets that would only fully balance the emissions over a very long horizon — described as 'in 100 years.' To the watchdog, a shopper reading 'net-zero climate footprint' on a carton would understand it to mean the product had no climate impact, or that any emissions had already been compensated — not that they would be, a century from now.

In February 2023 the Swedish Market Court agreed. It found the claim misleading — among other reasons, the word 'Net' appeared in small print while 'zero climate footprint' stood out, so the overall impression was of a product with no footprint at all. The court banned Arla from using 'net-zero climate footprint' in marketing products sold in Sweden. The ruling became a reference point across the Nordic countries for how carbon-offset claims may be made, and a warning that 'compensated eventually' is not the same as 'net zero.'
