Summary
Details
- The United States of America (USA)
Mandatory for obligated parties under the Clean Air Act RFS program. Small refinery exemptions and other relief mechanisms can alter obligations, but these are program-specific and not automatic. The proposal also discusses adjustments and accounting approaches that can materially affect obligations.

What’s Required
RFS compliance is an annual obligation for “obligated parties” (generally refiners and importers of gasoline and diesel). Obligations are expressed as Renewable Volume Obligations (RVOs), which are met through:
Physical blending of qualifying renewable fuels.
Acquisition and retirement of valid RINs.
Use of carryover mechanisms within program limits.
1) Determine obligated party status and calculate RVOs
Entities must determine whether they are obligated parties and calculate their annual RVOs based on EPA’s percentage standards and their volume of fossil fuel produced/imported. Compliance requires robust fuel accounting systems and controls because RVO calculations depend on accurate production/import data.
2) RIN acquisition, validation, and retirement controls
RINs are tradable compliance instruments. Obligated parties must:
Acquire sufficient RINs
Validate RIN integrity (fraud risk is a known RFS issue historically)
Retire RINs correctly in EPA’s compliance systems
This is a financial compliance program as much as an environmental one: RINs are material cost drivers and can be balance-sheet relevant.
3) Proposed 2026–2027 standards and compliance planning
EPA’s proposed rule for 2026 and 2027 affects forward procurement strategies, hedging, and long-lead investment decisions (renewable diesel, SAF, cellulosic fuels). EPA’s proposal summary describes establishing required volumes and percentage standards for 2026 and 2027 and related adjustments.
Reuters reported proposed higher blending volumes through 2027 and key features affecting credits generated from imported feedstocks, indicating material implications for RIN generation and compliance costs.
4) Rulemaking participation and scenario governance
Because this is a proposed rule, compliance teams must monitor Federal Register actions and consider submitting comments. Forward contracting for biofuels and RINs should be structured with regulatory change provisions, since final standards may diverge from the proposal.
Important Deadlines
EPA announced a proposed rule on June 13, 2025.
Rulemaking steps continue through public comment and eventual finalization; exact final effective dates depend on publication and EPA’s final action.
Current Status
Proposed for 2026 and 2027 volumes; existing RFS compliance continues under the currently effective standards. EPA maintains a docket and rulemaking page tracking the 2026–2027 proposal.
Penalties for Non-Compliance
Civil penalties under the Clean Air Act.
Requirement to make up deficits and potential additional compliance obligations.
Market exclusion risk: inability to demonstrate compliance can constrain fuel marketing.
Enforcement risk for invalid RIN use, including liability where due diligence is inadequate.
Examples of Known Violations
Under-calculating RVOs due to incorrect production/import accounting.
Retiring invalid or fraudulent RINs (weak due diligence).
Late submission of compliance demonstrations.
Double-counting or improper carryover of RINs.
