Brand Rating
Allbirds
Allbirds leads on carbon footprint transparency and natural materials (merino wool, TENCEL, sugarcane EVA). However, their "carbon neutral" claims rely heavily on offsets rather than absolute emission reductions, and the price point (£95-135 per shoe) puts them above many competitors. Strong B Corp credentials (82 score) and FSC-certified packaging are genuine positives. Known downside: the wool shoes have durability concerns reported by users, and the shift into synthetic materials (Tree Dasher) muddies their natural-fibre positioning.

Regenerative wool and sugarcane sourcing commitments and FSC-certified packaging; no formal biodiversity programme published.
Minimal repair or resale program; some recycled content in materials and FSC-certified packaging, but no take-back; durability concerns on wool styles.
Publishes product carbon footprints and is Climate Neutral certified; neutrality relies heavily on offsets rather than absolute Scope 3 reductions, and targets are not SBTi-verified.
Natural materials (wool, TENCEL, sugarcane EVA) replace petroleum synthetics across most of the range; some styles still use synthetics (e.g. Tree Dasher).
Certified B Corp (score ~82); public ESG reporting as a listed company; supplier and factory transparency published.
