Data Sources
You're assembling emission factors from scratch. Every. Single. Engagement.
Healthcare GHG inventories require emission factors from at least 3 EPA datasets, each in a different format, with different update cadences, and no healthcare-specific categorization. You download eGRID for electricity. The GHG Hub for combustion. Supply Chain Factors for Scope 3 procurement. Then you manually reconcile units, match NAICS codes to hospital departments, and pray your factor selection holds up in audit.
CliniCarbon does that work once, rigorously, and delivers it as a single annual reference you can trust.
What you get that raw EPA data doesn't give you.
Healthcare category mapping
60+ NAICS codes mapped to hospital-relevant categories. Know instantly which factors apply to Pharmaceuticals vs. Surgical Supplies vs. Anesthesia vs. Food Service.
Regulatory framework tags
Every factor marked with which frameworks accept it: GHG Protocol, Colorado BPS (HB21-1286), California SB 253, Joint Commission, Practice Greenhealth, ENERGY STAR.
Factor hierarchy guidance
When multiple factors match, we tell you which one to use and why. Geographic specificity beats temporal recency beats data quality tier.
Anesthetic gas quick-reference
The only emission factor reference with clinical context for desflurane, sevoflurane, isoflurane, and N₂O. Includes worked examples and reduction guidance.
Audit-ready provenance
Every factor traces to a specific source, version, table, and URL. Copy the citation into your inventory report appendix.
One workbook. Nine sheets. Full provenance.
Every factor includes source citation, publication year, geographic scope, uncertainty notes, and healthcare category. Plus a 4,400-word methodology document covering source selection rationale, factor hierarchy, unit conventions, and regulatory framework mapping.
- All Factors — 1,413 emission factors across Scopes 1, 2, and 3
- Healthcare Focus — 287 factors tagged to healthcare categories (Pharmaceuticals, Medical Devices, Anesthesia, Hospital Operations)
- Colorado & Regional — eGRID subregion factors for location-specific Scope 2
- Anesthetic Gases — Desflurane, Sevoflurane, Isoflurane, N₂O — GWPs with clinical guidance

- About — Edition metadata, publisher, update policy
Built on the same EPA data the industry trusts.
CliniCarbon draws from the same sources cited by the Eckelman et al. (2020) study in Health Affairs that established US healthcare at 8.5% of national emissions, embedded in Practice Greenhealth's Climate Impact Checkup tool used by 493+ hospitals.

Frequently asked questions
How is this different from downloading EPA data myself?
You could download eGRID, the GHG Hub, and Supply Chain Factors separately. CliniCarbon saves you that work and adds healthcare category mapping, regulatory framework tags, factor hierarchy guidance, anesthetic gas clinical context, and per-factor provenance metadata that don't exist in the raw data.
What regulatory frameworks does this support?
GHG Protocol Corporate Standard, Colorado Building Performance Standards (HB21-1286), California SB 253, Joint Commission Sustainable Healthcare Certification, Practice Greenhealth / Climate Impact Checkup, and ENERGY STAR Portfolio Manager.
How often is it updated?
Annually, aligned with EPA's January publication cycle for eGRID and the GHG Emission Factors Hub. Supply Chain Factors are updated when EPA/Cornerstone releases new versions.
Can I use this for non-US hospitals?
The current edition covers US facilities only (EPA sources + eGRID subregions). Canadian and international editions are planned.
Is there an API?
Not yet. An API with semantic search and programmatic access is planned for later in 2026. Reference subscribers will get priority access.
Who built this?
CliniCarbon is published by Lighthouse HLTH, founded by Nicolas Vinson. Nick previously built and exited shadow.eco, a carbon accounting SaaS bootstrapped in France and Quebec.
