Library of Things has negligible operational emissions and structurally reduces consumption through product sharing. Transparency is above-average for an SME through mission-lock governance and annual impact reporting. Critical gap: no formal operational emissions targets, supply chain quantification, or energy strategy—and academic critique questions whether sourcing new items rather than utilising existing goods contradicts sustainability claims.
