This reference table consolidates all emission factors used in Restoration Carbon Protocol calculations. It is the lookup document you use when completing a per-job carbon report — every factor needed for Categories 1, 4, 5, and 12 across all five job types is in this table, with source citations for audit purposes.

How often will this reference table be updated?
The RCP emission factor reference table will be updated annually following the release of updated EPA WARM, EPA Mobile Combustion, and DEFRA databases. Version numbers are included in the table header — always cite the version used in your per-job carbon report data quality notes.
What if I need an emission factor for a material not in this table?
First check EPA WARM v16 directly (available free at epa.gov/warm). Second, check the EPA EEIO database for the relevant industry sector. Third, check DEFRA’s Conversion Factors for Company Reporting. If none of these sources contain the specific material, use the closest proxy category and document the substitution in your data quality notes.
Are these factors suitable for use in EU CSRD reporting?
EPA and EPA WARM factors are US-specific but are accepted in most international ESG frameworks when accompanied by clear source citation. For EU CSRD reporting specifically, DEFRA factors (UK) or OECD emission factors may be preferred by auditors for non-US operations. The RCP will publish a DEFRA-specific factor table in a future supplement for EU-applicable reporting contexts.
