Proper Snacks has built genuine B Corp governance and plant-based positioning but fails to measure what matters. No Scope 1, 2, or 3 emissions data exists despite stating 2030 net zero. Supply chain and water impacts remain unmeasured. Packaging reductions and no-palm-oil commitments show intent; transparency and controversy profiles are clean.
