As of April 1, New Mexico's Clean Transportation Fuel Program is officially live. That makes New Mexico the fourth state in the country with an active clean fuel credit market, joining California, Oregon, and Washington. It is also the first program of its kind in the U.S. Southwest.
If you collect used cooking oil for a living, this matters more than you might think.
What is the program?
The short version is this. New Mexico now requires fuel producers and importers to gradually reduce the carbon intensity of the transportation fuels they sell in the state. The target is a 20 percent reduction by 2030 and 30 percent by 2040, measured against a 2018 baseline.
To meet those targets, fuel suppliers can either lower the carbon intensity of their own products or buy credits from companies that produce cleaner fuels. Renewable diesel, biodiesel, ethanol, and renewable natural gas are all eligible to generate credits under the program. The first compliance period runs from April through December 2026, with the first mandatory reports due by April 2027.
The program is modeled closely after California's Low Carbon Fuel Standard but simplified for a smaller market. It uses a similar credit and deficit system, and fuel pathway certifications already approved in other states can be adopted to speed things up.
Why this matters for UCO collectors
Here is where it gets relevant. Renewable diesel and biodiesel are expected to be the primary credit generators in the early years of the program. Both of those fuels run on feedstocks like used cooking oil, animal fats, and soybean oil.
Not all feedstocks are treated equally under these programs. Every feedstock has a carbon intensity score, and that score determines how many credits a gallon of fuel generates. Used cooking oil has one of the lowest carbon intensity scores of any feedstock in the renewable fuels supply chain. That means renewable diesel or biodiesel made from UCO generates more credits per gallon than fuel made from virgin soybean oil or other higher-CI inputs.
For producers trying to maximize their credit generation under New Mexico's program, UCO is the feedstock they want. That drives demand. And when demand goes up, pricing follows.
A new regional market
Until now, clean fuel credit markets have been concentrated on the West Coast. If you were a UCO collector in Texas, Arizona, or anywhere in the southern half of the country, those programs were geographically distant and had limited direct impact on your day-to-day business.
New Mexico changes that. It opens up a credit-backed market in the Southwest, which means feedstock routed into or through the region now carries additional value. For collectors and haulers operating in neighboring states, this creates a new buyer pool that did not exist before.
More states are watching
New Mexico is not the end of the road. Hawaii, Illinois, New Jersey, and New York all have active clean fuel standard bills in their legislatures. Pennsylvania and Massachusetts have also shown interest. None of those have crossed the finish line yet, but the momentum is clear.
Every new state that launches a clean fuel program increases the number of markets where low-carbon feedstock carries compliance value. And every one of those programs rewards the use of UCO because of its favorable carbon intensity score.
The bottom line
New Mexico is a smaller market. It is not going to move national UCO prices overnight. But it is another piece in a growing puzzle. More states adopting clean fuel standards means more demand for renewable diesel and biodiesel, which means more demand for the feedstock that makes those fuels possible.
If you collect used cooking oil, the trend line is working in your favor. More markets. More credits. More value for every gallon you pick up.
