Libraries set the boundary
Numbers assign responsibility
Emission factors are the constraint behind credible accounting. MeetCarbon turns authoritative standards into searchable libraries so organisations, parks and public institutions inventory, supervise and decide on one scope.

Governance Path
How factor libraries are governed
MeetCarbon Cloud does the governance; the website only shows Published + public results.Source → library → items: three layers, six steps.
Register the source
MeetCarbon Cloud · Source catalogue
First pin down where the factor comes from: domestic or international body, licence type, update cadence and quality grade. No source, no library.
Outcome
Source code (e.g. jst303, ipcc2006)
Why rebuild factor assets as libraries
The formula is simple. Credibility hangs on the standard, geography and version a factor belongs to. When grid, fuel and process factors sit in one flat list, teams mix scopes and inventory, disclosure and audit no longer line up.
MeetCarbon treats factor libraries as dual-carbon infrastructure: the public layer uses libraries to cut misuse; MeetCarbon Cloud handles versioning, review, publish and system access so lookup, traceability and reuse are the default.

Assurance
Inventory, PCF, regulatory filing and third-party review
What this delivers
Libraries first, then numbers
Organise factors by standard and source first, then search inside a library — so scopes are not mixed by accident.
Domestic authority, international comparison
JS/T 303, MEE notices and national standards sit alongside public international factors for domestic compliance and cross-border disclosure.
Versioned and auditable
Enterprise governance covers source catalogues, version lock and publish review so changes can be traced for verification.
Query as a service, systems can connect
The public layer offers browse and search; MeetCarbon Cloud adds unified query, import, connectors and APIs into accounting systems.
Where it lands
From public-institution accounting to organisational inventory and product footprints — pick the right library so methodology debates stay small.
Public-institution accounting
JS/T 303 library for appendix factors — one Scope 1/2 boundary for offices and public institutions.
Organisational GHG inventory
Grid and fuel libraries together for activity conversion, scope notes and year-on-year comparison.
Product footprint and disclosure
Sector methodologies plus international libraries for LCA, labels and cross-border disclosure.
