Winnow is a food-waste-reduction SaaS company with genuine product-level impact: 28,000 tonnes of food waste prevented annually across 3,500+ client sites. Its own operational carbon footprint data is stale (last published FY20, 645 tCO₂e) and absent from recent reporting. No updated Scope 1, 2, or 3 emissions disclosed post-2022; hardware supply chain emissions likely grew with deployment scale.
