Rubies in the Rubble is a small food waste company with a genuinely lower environmental footprint than peers, but has published almost no verified emissions data. The business model works: 800+ tonnes of produce diverted, circular packaging innovation, clean record. The weakness is consistency: no Scope 1, 2, or 3 quantification, no SBTi targets, and absolute emissions likely rising with 146% YoY growth.
