New Mexico’s Clean Transportation Fuel Standard
Regulated parties in the Clean Transportation Fuel Program (CTFP) must meet state standards of carbon intensity by either maintaining a carbon intensity below the standard for their fuel or by obtaining credits that allow them to meet the standard. The carbon intensity standards decrease each year.
Below are the annual fuel standards for gasoline, diesel, and their substitutes.
Gasoline and Gasoline Substitutes: (Table 1)
| Year | Carbon Intensity (gCO2e/MJ) | Percent Reduction |
| Baseline (2018) | 95.61 | 0.0% |
| 2026 | 93.89 | 1.8% |
| 2027 | 92.45 | 3.3% |
| 2028 | 89.87 | 6.0% |
| 2029 | 85.09 | 11.0% |
| 2030 | 76.49 | 20.0% |
| 2031 | 75.53 | 21.0% |
| 2032 | 74.58 | 22.0% |
| 2033 | 73.62 | 23.0% |
| 2034 | 72.66 | 24.0% |
| 2035 | 71.71 | 25.0% |
| 2036 | 70.75 | 26.0% |
| 2037 | 69.80 | 27.0% |
| 2038 | 68.84 | 28.0% |

Determining carbon intensities with NM-GREET
NMED uses a mathematical model known as New Mexico Greenhouse Gases, Regulated Emissions, and Energy use in Technologies, or “NM-GREET,” to determine the carbon intensity of transportation fuel. This carbon intensity “score” is used to allocate credits and deficits in the CTFP. Clean fuel programs in California, Washington, and Oregon also use similar models.
NMED adapted NM-GREET from the GREET model developed by Argonne National Laboratory. It is a thorough “lifecycle analysis” model that accounts for greenhouse gas emissions at all stages of a fuel’s life. In the transportation sector, this is sometimes known as a “well-to-wheels” analysis and accounts for emissions from raw material extraction through production, distribution, and final use.
What is my carbon intensity score?
Your fuel carbon intensity score can be determined in three ways:
- For fuel commonly used in New Mexico, use Lookup Table carbon intensities, which were created using NM-GREET
- For fuel with carbon intensity values already approved in other state programs, you may use these carbon intensities until the end of the program’s first compliance period July 1, 2026
- For fuel without pre-determined carbon intensity scores, you may seek your own “fuel pathway” using NMED’s Tier 1 and Tier 2 calculators, which are interfaces for the NM-GREET model

How does the program calculate credits and deficits?
Under the Clean Transportation Fuel Program, NMED determines credits and deficits, expressed as metric tons of carbon dioxide equivalent per unit of energy, by using a calculation that incorporates:
- The difference between a fuel’s carbon intensity and the carbon intensity standard for the year
- How much fuel the regulated party imported, produced, or dispensed based on participant reports
- The energy density of the fuel, and
- If the fuel is consumed in an electric vehicle.
