| Caveat | The carbon neutral claim attached to ROZ does not hold up. It appears on a third party brand aggregator rather than on ROZ own site, which names no climate certifier at all. The only related certification belongs to Boox, its reusable shipping box supplier, and covers the boxes rather than ROZ manufacturing, sourcing or operations. That Boox certification has itself expired, according to The Climate Label own directory. ROZ returns no entry in the B Lab, 1% for the Planet or Climate Label registers. The PETA listing the brand claims could not be found in PETA own database, where searches for ROZ return the unrelated brand Rozuri. |
