Lucy & Yak publishes materials and circularity data but fails on emissions. No Scope 1, 2, or 3 data exists despite partnering with Greenly. No reduction targets, no trajectory tracking. The Re:Yak buyback is measurable but consumer complaints about declining quality and rapid releases undermine the circular claim.
