Allbirds is an American-New Zealand company making shoes and clothes from natural materials such as Merino wool and eucalyptus tree fibre, which they blended together to invent a new yarn called Trino. Every product comes with a carbon footprint, encompassing emissions in production, development, customer use and disposal.
Natural materials such as wool and tree fibres.
Carbon footprint available.
Allbirds focus on reducing their carbon footprint through regenerative agriculture, renewable materials and responsible energy; they already claim to be carbon-neutral through offsets, and are working to reduce their footprint to eliminate the need for offsets.
Closing the loop
Allbirds don't appear to have a scheme for dealing with shoes at the end of their life.
