Allbirds' latest footprint is 21,453 tCO2e for 2023, submitted to the Climate Label with third-party verification stated: 446 t of Scope 1, 281 t of market-based Scope 2 and 20,726 t of Scope 3, which is 96.6% of the total. No category split was published, and the 2025 10-K says 2025 reporting is not yet available. Its main claim, a carbon neutral business since 2019, rests on offsets, which earn no credit. Progress on its 42% absolute cut by 2030 is self-reported at 20%; per-product intensity fell, which is not an absolute cut. Its regenerative wool goal stood at 1%. No water footprint was found. The new owner has published no emissions data.
