Verified LCA Reuse Study with CarbonBright
Borrow Cup, a joint venture by Hubbub and Reposit, partnered with CarbonBright to verify the environmental impact of its Glasgow-based reusable-cup scheme, which lets customers borrow and return cups at participating cafés.
Borrow Cup needed to quantify and verify its sustainability impact to engage stakeholders and attract partners, but had limited visibility into its environmental footprint beyond carbon, relied on manual data collection that limited scalability, and lacked consistent benchmarks for reuse versus single-use systems.
CarbonBright's AI-powered platform ran cradle-to-grave impact assessments, quantified reductions in carbon, water, and waste, modeled operational scenarios to optimize performance, and generated audit-ready results aligned with sustainability frameworks.
- Reusable cups outperform single-use alternatives after only a few uses
- Repeated reuse reduces impact across carbon, water, and human toxicity categories
- Efficient washing and low-emission transport amplify the sustainability benefit
