Bower Collective is a certified B Corp with genuine circular economy credentials—the BowerPack reusable system has diverted 11 million plastic bottles from landfill. However, it publishes no absolute emissions data, Scope 3 quantification, or science-based reduction targets. Carbon Negative certification relies on offsets, not disclosed reductions. Transparency is strong for size; climate rigour is weak.
