Methodology · Open & versioned
The full Carbon Sight methodology is published, version-numbered, and changelogged. Every factor traces to a free, government, or peer-reviewed source — 123 institutional LCAs and 200+ DOI-cited papers behind 215,000,000+ data points.
Principles
No ecoinvent. No GaBi. No Sphera. Every factor traces to a free, government, or peer-reviewed source anyone can inspect without a $20K–$80K license.
Built by the team behind a CARB LCFS Tier 2 dairy-biogas pathway. Our carbon-intensity scores have been defended before a state regulator — that bar applies here.
Each SKU gets a one-page PDF certificate, a public methodology page, and a clickable verification URL.
Independent public authorities must agree before a number ships. The result carries a confidence band — never false precision.
Including end-of-life and recycling credits via EPA WARM. Cradle-to-gate is where greenwashing hides; we don't stop there.
Carbon Sight measures what a product emits. We never sell, bundle, or net out offsets — a certificate is a measurement, not an indulgence.
The evidence base
The named authorities below anchor the engine. Peer-reviewed sources — Nature, Science, IPCC, The Lancet — fill and cross-check the gaps, cited by DOI wherever they touch a certificate.
Standards alignment
The international standard for product carbon footprints. Third-party audit tier delivers ISO 14067-aligned verification with an independent auditor co-signature.
Life-cycle boundary and allocation logic follow the GHG Protocol Product Standard.
Certificates produce the product-level, source-attributed numbers these regimes ask suppliers for.
