The platform
Carbon Sight synthesizes 123 government & institutional LCAs and 200+ peer-reviewed papers into 215,000,000+ data points — then forces independent sources to agree before a number reaches a certificate.
How a score is built
EPA, DOE Argonne GREET, NREL FLCAC, DEFRA, ADEME Agribalyse, EC3, IPCC, Bath ICE — 123 institutional LCAs plus 200+ DOI-cited papers, normalized into one schema.
Materials, processing, distribution, use phase, and end-of-life — including recycling credits via EPA WARM. Cradle-to-gate shortcuts don't survive an audit.
Every factor is checked against at least two independent public authorities. Where they disagree, the engine resolves it and records the spread.
The certificate states the number, the band, and the named source behind every line item — each one clickable, each one public.
Worked example
| Life-cycle stage | Contribution | Public source |
|---|---|---|
| Primary & recycled aluminum production | 0.31 kg CO₂e | USLCI / NREL FLCAC |
| Can forming & filling energy | 0.09 kg CO₂e | GREET 4.0 · EPA EF Hub |
| Distribution & retail | 0.08 kg CO₂e | EPA EF Hub |
| End-of-life recycling credit | −0.03 kg CO₂e | EPA WARM |
Every line item above resolves to a free, public, or DOI-cited source. That trail prints on the certificate and lives at a public verification URL.
Coverage
Branded consumer food products and agricultural inputs, anchored by ADEME Agribalyse and peer-reviewed food-systems meta-analyses.
Construction EPDs via EC3 and materials factors from the University of Bath ICE database — the categories CBAM prices first.
GREET fuel pathways, regional grid intensity, packaging and polymer production, and end-of-life accounting via EPA WARM.
Public QA
The free consumer app at app.carbonsight.io scores products against the identical engine that issues certificates. Open methodology means our mistakes are visible — and fixed in version-numbered updates.
