EPA Renewable Fuel Standard — D3 RINs for RNG

activeUS Federalfederalcredit marketRenewable natural gas (RNG)

ValueMarket-priced D3 (cellulosic) RINs per gallon-equivalent of RNG used as transportation fuel; final 2026 cellulosic RVO 1.36B RINs and 2027 1.43B RINs (RNG ~91% of category); total RVO 26.81B RINs (2026) incl. 70% small-refinery-exemption reallocation

DeadlinesOngoing annual compliance market; final 2026-2027 rule published 4/1/2026

RequirementsEPA company/facility/fuel registration under 40 CFR Part 80 with approved biogas/RNG pathway; pipeline injection and contractual tracking to transportation use; quarterly reporting; QAP verification typical for marketability

CaveatsRIN prices volatile and RVO set below industry-projected RNG growth (potential D3 price pressure); EPA removed renewable electricity (eRINs) as qualifying fuel — biogas-to-power earns no RINs; import RIN reduction deferred to ~2028
