Measure Your Fashion's Real Impact
Every garment has a carbon footprint. Closetary calculates it using real data — not estimates — from UK government sources and academic research.

Our Methodology
How We Calculate Carbon Footprints
Our carbon scoring engine uses a Lifecycle Assessment (LCA) approach aligned with PAS 2050, calculating emissions across the full garment lifecycle.
Material Analysis
Parse material composition (e.g., 80% cotton, 20% polyester) and apply Higg MSI emission factors per material.
Manufacturing Impact
Apply country-of-origin multipliers reflecting energy grid carbon intensity during manufacturing.
Transport Emissions
Calculate origin-to-UK transport emissions based on distance and shipping method.
Care & Washing
Estimate lifetime washing impact: water temperature, drying method, wash frequency, and garment lifespan.
Total & Score
Sum all stages, normalise to 0–100 scale (24 kg CO₂e = 100), assign rating from Excellent to Very High.
Carbon Score Scale
Every item gets a score from 0 to 100 (lower is better)
0–20
Excellent
21–40
Good
41–60
Moderate
61–80
High
81–100

Take Action
Every Action Saves Carbon
Closetary calculates exactly how much CO₂ you save with each sustainable choice.
Resell
Every resold item displaces a new purchase, saving the full production carbon footprint.
Donate
Charity donations extend garment life and divert clothes from landfill.
Swap
Peer-to-peer swaps refresh your wardrobe without any new production emissions.
Repair & Upcycle
Extending a garment's life by just 9 months reduces its carbon footprint by ~20-30%.
