The largest reference-grade
carbon model ever built.

123 government and institutional LCAs — from national laboratories, government agencies, and international scientific bodies. 200+ peer-reviewed academic papers from Nature, Science, IPCC, The Lancet, and the leading journals. 215 million-plus scientific data points. Every score cited and traceable to its source — no other consumer carbon score does this. The same datasets EU CSRD, US SEC, CARB, and CBAM regulators use. Zero commercial databases. Every number Carbon Sight publishes traces to a citable source you can read for yourself.

The 123 government and institutional LCAs powering every score.

123 independent regulator-grade LCAs, each maintained by an institution that actually files regulatory carbon pathways for a living — Argonne National Laboratory, EPA, NREL, ADEME, DEFRA, IPCC, FAO, IRENA, the European plastics industry, the UK building research community, Apple's own product team, and growing. Plus 200+ peer-reviewed academic papers from Nature, Science, IPCC, The Lancet, the Journal of Industrial Ecology, and every meta-analysis worth citing — the academic backbone.

When you scan a coffee cup, ten of these sources contribute a piece of the answer. When you scan a phone, fifteen sources cross-check each other. You see one number. Behind it: the supermodel, cross-referenced and citable to the last gram.

Queued for integration

The next 15 sources scheduled for integration into the Carbon Sight engine over the coming weeks of focused work. Each adds either depth, geographic coverage, or sector coverage that the current stack lacks.

Food, agriculture, and beverages

Construction, building materials, and embodied carbon

Government emission factors (corporate carbon accounting)

Plastics, chemicals, and packaging

Transport and logistics

Electricity and grid carbon

Referenced — methodology under review

These sources we have reviewed, cite in our methodology, or plan to ingest later. They expand coverage to additional geographies, sectors, and specialty domains. Many will move to "Queued" status as we work through them.

Additional national LCA databases

Sector-specific and specialty

Reference frameworks and aggregators

Additional government and industry sources

How this list grows

This page is a living document. New sources are added as they are reviewed by our methodology advisory board. Sources move from Referenced to Queued when an integration sprint is scheduled, and from Queued to Live when ingestion is complete and the source has been validated against existing references.

The library of derived components — the proprietary asset that emerges from synthesizing across all of these sources — is documented separately in our engine architecture. See the methodology page for the underlying tier system and confidence framework, or the public audit log for what we hand-verify each cycle.
