Dairy / agricultural digester → pipeline RNG
US & Canada — the compliance credit depends on where the fuel is sold
Anaerobic digestion of dairy or agricultural manure, upgraded to pipeline-quality biomethane and sold as a transportation fuel.

How they stack: earned together on the same project — US Renewable Fuel Standard (RINs) + California LCFS (RNG as transport fuel); US Renewable Fuel Standard (RINs) + Oregon Clean Fuels Program; US Renewable Fuel Standard (RINs) + Washington Clean Fuel Standard; US Renewable Fuel Standard (RINs) + British Columbia Low Carbon Fuels; US Renewable Fuel Standard (RINs) + Canada Clean Fuel Regulations.
Eligibility layers: credits may qualify for CORSIA aviation demand — assessed per program, category and vintage.
Verify in the source
- US Renewable Fuel Standard (RINs): D-code and RIN generation depend on EPA-approved pathway for the feedstock; confirm pathway petition status.
- California LCFS (RNG as transport fuel): Requires a certified CI pathway (Tier 1/Tier 2); manure-derived RNG can carry a strongly negative CI.
- Green-e Renewable Fuels (voluntary RNG attribute): Voluntary attribute. The same environmental attribute generally cannot be both sold voluntarily and claimed under a compliance program - check exclusivity before stacking.
- Climate Action Reserve: Protocols not yet in the library - add CAR protocols to enable change tracking for this pathway.
- American Carbon Registry: Standard not yet in the library - add ACR to enable change tracking.
Landfill gas → RNG
US & Canada
Collection of landfill gas, upgraded to RNG and dispensed as transport fuel.
