CarGlow OS
Every number, traceable to a method version.
CarGlow never publishes a sustainability figure without the calculation behind it. This page documents exactly how our ESG numbers, sustainability scores, and reports are computed — so anyone can check our work.
ESG method v1.0-draft
Litres saved per completed, evidence-verified wash, by vehicle class: bike 30L, hatchback 100L, sedan 120L, SUV 150L, premium 160L. CO₂e avoided is computed at 1.1 grams per litre saved. These are the only baselines the ledger ever uses — nothing is estimated or rounded up for effect.
Every wash writes exactly one append-only ledger entry per completion. If a supervisor rejects a photo after the fact, the correction is a second, compensating entry — never a deletion — so the ledger's history always matches what actually happened.
Sustainability score method (sustainability-v1.0-draft)
An apartment community's sustainability score blends three real, measured components:
Coverage — 40%
Share of registered vehicles actually washed in the period.
Consistency — 30%
Share of days in the period with at least one completed wash.
Complaint health — 30%
Share of complaints resolved or closed in the period (an apartment with zero complaints scores full health here — it isn't penalized for having nothing to resolve).
The weights above are exactly what the score uses today. If they ever change, the method version changes with them — a score's method version always tells you which formula produced it.
Employment method (employment-v1.0-draft)
"Certified cleaners" counts cleaners at certification level 1 or above — certification is a ladder, so level 0 means onboarded but not yet certified, and is reported separately as total onboarded cleaners.

What's pending
Every figure on this site is labeled "not yet independently certified." We compute honestly from real, evidence-verified jobs today, and intend to seek third-party certification of the methodology before any of these numbers are used in official government publication.
