DOE publishes counterfactual GHG emission factor for biogas and RNG life cycle assessment
DOE Generic Counterfactual GHG Emission Factor for LCA (January 2025)U.S. Department of Energy (DOE)United States
Announced
Jan 2, 2025
Description
The U.S. Department of Energy has published a technical document providing generic counterfactual greenhouse gas emission factors for life cycle assessment of manure-derived biogas and renewable natural gas. This guidance supports consistent LCA methodology application for RNG and biogas pathways, enabling standardized emissions accounting and comparison aligned with ISO 14040/14044 principles.
