Subito’s Second-Hand Effect Report
Thursday 15th October, 2026
Subito commissioned climate-tech company Vayuu to estimate the environmental impact of sales on its second-hand marketplace. The resulting report put a memorable figure on the idea that buying used can replace buying new: more than 15 million items sold in 2025 could have avoided 518,000 tonnes of CO₂, based on buyers’ reported behaviour and the study’s calculations.
Why it worked: It turned a fuzzy virtue into a hard, timely stat using third‑party methodology and everyday equivalents, giving journalists an instant headline.
The lesson: Consider commissioning an independent audit that converts a common behaviour into a single headline number with vivid, locally relevant comparisons.
