The newest of the West Coast fuel standards, and the one whose credit balance has moved furthest fastest. Washington runs a Clean Fuel Standard and a separate cap-and-invest programme covering the same fuel suppliers — two obligations, two instruments, frequently conflated.
The Clean Fuel Standard is distinct from Washington's cap-and-invest programme. Fuel suppliers can be covered by both, with separate instruments and separate obligations under each.
Ecology sets an annual carbon intensity standard. Fuels above it generate deficits, fuels below it generate credits, both in metric tonnes. Registered parties balance the two annually, and a deficit is a violation unless the party participates in the credit clearance market.
The mechanics resemble the other West Coast standards, with two features specific to Washington: a two-year opening compliance period, and an electricity credit stream that is calculated rather than metered.
Six features of the Washington regime, including two that regularly cause the programme to be misread.
A deficit is a violation unless the party participates in the credit clearance market. Because participation is itself the compliance route, the statutory penalty is not the practical bound on compliance cost — the clearance market maximum is.
The requirement moves from 2% to 7% and onward across the middle of the decade. A market that looks comfortable on last year's balance can tighten quickly against a schedule stepping this fast.
A substantial part of the electricity credit stream is calculated by Ecology from state records rather than metered, and is revised after year-end. The most recent year in any dataset is provisional.
The first compliance period covered 2023 and 2024 together. Any year-on-year comparison that treats 2023 as a standalone compliance year is comparing the wrong things.
Fuel suppliers may be covered by both the Clean Fuel Standard and cap-and-invest. They are separate obligations with separate instruments, and neither discharges the other.
Washington applies indirect land use change values to crop-based pathways, in the same direction as California and the opposite direction to some other programmes — which changes the relative value of a crop-based barrel.
Where you stand under Canada Clean Fuel Regulations (CFR), what it costs, and which levers reduce the bill — mapped by the team.
Six ways we support parties registered under the Washington standard.
Translating the annual standard into a position, with attention to the steep near-term steps in the schedule.
Ecology registration, pathway determination and the recordkeeping the programme requires.
Structuring metered and calculated electricity credit generation, including how restatements affect a reported position.
Working through both obligations where a supplier is covered by each, without double-counting or assuming one offsets the other.
How a Washington barrel compares against Oregon, California and British Columbia, and where a volume is best placed.
Quarterly and annual reporting, clearance market participation and the evidence Ecology expects on review.
Published analysis from Climate Decode on Washington and its neighbouring markets.
The neighbouring standard, on a very different point in its own credit cycle.
The separate carbon market covering many of the same fuel suppliers, with its own allowances and auctions.
Seven programmes pricing the same barrel, each with its own unit, trajectory and clearing price.
The carbon intensity schedule is set out in WAC 173-424. Ecology publishes credit transfer data periodically; note that credit totals for the most recent year are provisional, because a substantial part of the electricity credit stream is calculated after year-end and has historically been revised upward.
No. They are separate programmes under separate statutes. The Clean Fuel Standard is a lifecycle carbon intensity standard on transport fuels under RCW 70A.535. Cap-and-invest is an economy-wide carbon market under RCW 70A.65. A fuel supplier can be covered by both, and compliance with one does not discharge the other.
A deficit is a violation unless the party participates in the credit clearance market. That makes participation a compliance route rather than simply a way to buy credits, and it means the statutory penalty is not the practical bound on compliance cost.
A significant part of the electricity credit stream — particularly non-metered residential charging — is calculated by Ecology from state records rather than measured directly, and is revised after year-end. The most recent year in any published dataset should be treated as provisional.
The programme opened with a combined 2023–2024 compliance period. Any analysis that treats 2023 as a standalone compliance year, or compares it directly against later single years, is comparing different things.
The requirement moves from 2% to 7% across the middle of the decade and then increases in equal annual increments through to 45% in 2038. A market that appears long against a recent balance can tighten quickly against a schedule stepping at that rate.
All three are lifecycle CI standards with credits in metric tonnes, but they sit at different points in their trajectories and their credit balances have moved in different directions. A credit in one does not transfer to another, so the comparison matters for where a volume is placed rather than for moving instruments between programmes.
