In 2025, 23.25 billion RINs were distributed under the RFS. One standout data point included a significant increase in D3 RINs coming from cellulosic ethanol—93% over the 2024 total.
The U.S. EPA on March 27 announced the RFS cellulosic waiver credit (CWC) price for 2025 has been set at $1.91, up from $1.61 for 2024. The CWCs are being made available due to the agency’s decision to reduce the 2025 cellulosic RVO.
How Corn Kernel Fiber Ethanol Reshaped the Industry
The U.S. EPA on March 27 finalized the 2026 and 2027 RFS RVOs at levels higher than originally proposed. The increase is attributed to the decision delay implementation of provisions penalizing imported fuels and feedstocks until 2028 or later.
