Allbirds has announced the launch of its new Carbon Neutral initiative. The new carbon footprint indicator number concept is latest carbon-neutral initiative from the brand, whereby it has created a label for each of its products with an indicator number revealing the item's carbon footprint. 

The sticker's number will show in kilograms how much Co2e was emitted to create the shoes. The footwear brand, whose key material is Merino wool, already became 100% carbon-neutral in 2019. 

Allbirds Carbon Footprint sticker is now available on its Wool Runner Shoes from allbirds.co.uk.
