OUR MARKET JOURNEY
Washington’s Clean Fuel Standard (WA CFS) is one of the new entrants into the West Coast’s low carbon fuel policy triad, and cCarbon’s early work in this market reflects our forward-looking commitment to modeling emerging programs with analytical precision and policy fluency. While borrowing the structural backbone from California and Oregon, Washington’s program carves out its own identity, particularly in the way it frames compliance, regional fuel dynamics, and the strategic role of electrification.
Our WA CFS market model begins with a granular assessment of vehicle stock and sales projections across light-, medium-, and heavy-duty segments. These fleet forecasts anchor our estimates of fuel volumes, both fossil and alternative, and inform credit the and deficit calculations relative to Washington’s regulatory carbon intensity benchmarks. The model is then calibrated using state-released data, ensuring it mirrors actual market behaviour and regulatory alignment.
Washington’s program structure introduces new regional considerations for market participants. The state’s heavy reliance on imported clean fuels, the interplay with regional logistics hubs, and early signals from electricity crediting all contribute to a market that, while modeled after its West Coast peers, requires its own strategic playbook.
At cCarbon, our early modeling work in the WA CFS market is not just about projecting balances, it’s about understanding the policy architecture, anticipating credit price behaviour, and equipping stakeholders to navigate Washington’s evolving clean fuel economy with confidence.

PROGRAM OVERVIEW
Washington’s Clean Fuel Standard (CFS), implemented by the Department of Ecology, is a key initiative to reduce greenhouse gas emissions from the state’s transportation sector. Officially launched on January 1, 2023, the CFS sets a performance-based, fuel-neutral standard aimed at cutting the carbon intensity (CI) of transportation fuels by 20% below 2017 levels by 2034. The rule was authorized under HB 1091, passed in 2021, after several years of legislative debate and stakeholder engagement.
On 17th May 2025, Washington State updated its clean fuels policy with the passage of Second Substitute House Bill 1409 in 2025. This new law not only raises the bar for carbon intensity (CI) reduction but also introduces a sophisticated framework for compliance, enforcement, and transparency.
This legislative revisions have increased the stringency of the program’s CI reduction trajectory, mandating annual declines of approximately 3–4% starting in 2026. The updated Clean Fuel Standard law requires fuel suppliers to gradually reduce the carbon intensity of transportation fuels to 45% below 2017 levels by 2038.
The program builds on the design of California’s LCFS and Oregon’s CFP, encouraging cleaner fuel use without mandating specific fuels or technologies. The goal is to foster a flexible, market-driven transition to low-carbon transportation options while supporting in-state economic development and public health benefits.
Key Features:
Performance-Based Standard: Sets a fuel-neutral standard to reduce carbon intensity (CI) of transportation fuels.
Carbon Intensity Targets: Aims to cut CI 20% below 2017 levels by 2034 and 45% below 2017 levels by 2038.
Market-Driven Approach: Encourages cleaner fuels without mandating specific fuels or technologies, supporting economic development and public health.
Historical Context and Policy Development
Washington’s CFS grew from state climate policy commitments, including the Climate Commitment Act.
Low-carbon fuel discussions began in 2009, delayed until state bodies aligned.
Program design incorporated stakeholder workshops, economic assessments, and technical modeling.
Rules finalized in 2022 ensure feasible CI reduction targets with economic balance.
The first compliance year began in 2023 with a 0.5% CI reduction target.
- Price per Ton $26.82 (July 2025)
- Annual Emissions 1.06 MMT of Deficits in 2024
- Market Value $28.4 Million worth of deficits in 2024
- Program Start Date 2023
- Legislated Until 2028
- Number of Participants 200
- Member States State of Washington
Carbon Intensity and the Compliance Curve
Carbon intensity (CI) is measured in gCO₂e/MJ and evaluated on a full life-cycle basis, including production, transport, and use, with a baseline set to the 2017 average CI of gasoline and diesel.
Compliance
- • Fuels below CI target generate credits; above generate deficits
- • Compliance required annually via internal credit generation, trading, or banked credits
- • Ecology sets yearly CI targets, tightening toward 2034
Credit and Deficit System
A market-based compliance mechanism manages carbon intensity in fuels.
Credits are distributed via:
- • Generated by producers or importers of low-CI fuels such as renewable diesel, ethanol, biodiesel, electricity, hydrogen, and RNG
- • Fully tradeable and bankable indefinitely
- • Credit Clearance Market acts as a price cap during shortages to contain costs and ensure market stability
Compliance entities, mainly gasoline and diesel suppliers, must hold enough credits to cover their deficits.
Participants in the LCFS Market
Washington also allows voluntary opt-ins
Enabling electric utilities and fleet operators to earn credits for displacing fossil fuel use.
Key Features:
- • Regulated parties: Importers/producers of gasoline, diesel, and fossil fuels.
- • Credit generators: Low-CI fuel providers, utilities (for EV charging), hydrogen suppliers, and RNG producers.
Recent Updates and Future Directions
