45Z Tax Credit Extended Through 2029 as SRE Petitions Hit Record Highs
Big news for the renewable fuels industry: the 45Z clean fuel credit is now extended through 2029, giving producers a major boost. At the same time, a record-breaking 195 Small Refinery Exemption (SRE) petitions are pending with the EPA—raising fresh concerns for RIN markets and RFS compliance. Here’s what it means for your business.
Public Feedback on EPA’s Proposed 2026–2027 RFS Volumes
The EPA’s proposed RFS volumes for 2026–2027 have sparked a wave of public feedback from across the renewable fuels industry. From strong support for ethanol blending targets to concerns over RIN reductions and SRE policies, stakeholders weighed in during the July 8 hearing. RINSTAR summarizes key testimonies and what they mean for the future of the RFS program.
Unlocking Carbon Intensity: How the GREET Model Empowers Renewable Fuel Producers
Carbon intensity plays a crucial role in renewable fuel production and compliance. The GREET model, developed by DOE and Argonne National Laboratory, allows producers to accurately calculate their lifecycle emissions, improve operations, and unlock incentives like RINs and tax credits. Explore how this tool supports the renewable fuels industry.
Supreme Court and D.C. Circuit Deliver Legal Wins for Renewable Fuel Standard Stability
In recent legal decisions, the U.S. Supreme Court and D.C. Circuit Court upheld vital components of the Renewable Fuel Standard (RFS), providing greater certainty for biofuel producers, farmers, and refiners nationwide.
Mixed Reactions Emerge Following EPA’s Proposed RFS Targets for 2026–2027 and Finalized 2024 Cellulosic Volumes
On June 13, 2025, the EPA proposed ambitious Renewable Fuel Standard (RFS) targets for 2026 and 2027 while finalizing a downward adjustment to the 2024 cellulosic biofuel obligation. The proposal sparked praise from agriculture and biofuels advocates, who welcomed stronger blending goals and support for domestic energy. However, renewable natural gas and biogas producers raised concerns over the limited growth outlook for cellulosic fuels. Explore how stakeholders across the RFS landscape are reacting and what to expect next.
EPA Unveils Proposed 2026–2027 RFS Targets and Finalizes 2024 Cellulosic Adjustments
On June 13, 2025, the EPA released a major update to the Renewable Fuel Standard—proposing ambitious RVOs for 2026 and 2027 and finalizing a reduction in the 2024 cellulosic target. The proposal outlines significant blending increases, new methodology, and the removal of E-RINs, signaling a pivotal moment for the renewable fuels industry.
How Methane-Tracking Satellites Are Shaping the Future of RFS and RNG Compliance
With the launch of MethaneSAT and Tanager 1, real-time methane tracking is entering a new era. These satellites could revolutionize Renewable Natural Gas (RNG) monitoring under the RFS, improving emissions transparency, RIN compliance, and supply chain accountability.
What Are Obligated Parties Under the RFS? Roles, Responsibilities & Compliance Support
Under the Renewable Fuel Standard (RFS), obligated parties—such as refiners, importers, blenders, and exporters—are responsible for meeting Renewable Volume Obligations (RVOs). Learn how these key players contribute to renewable fuel blending and how RINSTAR’s compliance tools can support their unique regulatory needs.
Renewable Diesel vs. Biodiesel: Key Differences, Benefits, and Why It Matters for Clean Fuel Progress
As the biofuels market grows, the debate between renewable diesel and biodiesel continues. Both are made from similar feedstocks, but their chemical composition, performance, and infrastructure compatibility set them apart. Learn how these fuels differ, why renewable diesel is gaining market share, and what it means for the future of clean energy.
