Announcements
Under the rule for the Clean Transportation Fuel Program (CTFP), the New Mexico Environment Department will post certain updates here, on our data management system, ARCS, and send an email to subscribers to our CTFP GovDelivery listserv.
May 2026 Map release: CTFP participants may refer to this map to determine locations where new Fuel Supply Equipment (FSE) projects may be eligible for enhanced FSE credits. Map: Enhanced FSE Credit Eligibility (PDF)
- To incentivize expansion of low-emission modes of transportation in New Mexico, organizations in CTFP may generate FSE “capacity” credits from newly installed clean fuel infrastructure, including electric vehicle chargers and equipment for dispensing other low-carbon fuel. These capacity credits provide a boost on top of FSE “fuel” credits in the beginning of the equipment’s lifetime by filling the gap between credits for actual use of the fuel supply equipment and its expected optimal use.
- CTFP further prioritizes the expansion of clean fuel infrastructure in areas with annual household incomes equal to or below New Mexico’s average. FSE projects in such areas are eligible to receive a higher total FSE capacity credit value, known as enhanced FSE credits. Applicants may also qualify for enhanced FSE credits in other zip codes if they demonstrate limited access to clean fuel compared to the rest of New Mexico.
For more detailed information about eligibility, please see Section 304 of the full-text CTFP rule.
May 2026 map release: To meet CTFP’s credit revenue obligations, Electric Distribution Utilities (EDUs) may refer to this map to determine which areas in New Mexico meet CTFP’s definition of underserved communities. Map: EDU Credit Revenue Provision (PDF)
- Under the CTFP, EDUs that earn and sell credits from dispensing electricity as a transportation fuel for residential electric vehicles (non-metered residential electric vehicle charging) must reinvest 100% of revenue from those sales into transportation decarbonization and electrification projects. 50% of that revenue must support such projects in low-income and underserved communities.
For more detailed information about EDU credit revenue, please see Section 305 of the full-text CTFP rule.
June 2026 EDU Carbon Intensities (CIs) release: EDUs and other CTFP participants may refer to these values and calculations when estimating credit generation from electricity dispensed for transportation. EDU CIs Table & Methodology (PDF) & EDU CI Calculations (XLSX)
- The CTFP incentivizes the use of electricity as a transportation fuel, and reserves a specific role for EDUs who already dispense electricity for charging electric vehicles (EVs) at residences. EDUs generate monetizable credits from this portion of the electricity they distribute.
- To get the most accurate picture of how carbon-intensive an EDU’s electricity is, NMED collects information annually about the mix of energy sources (like coal, wind, or natural gas) used to power a specific EDU’s local grid. NMED uses this fuel mix data to calculate EDU-specific carbon intensities (CIs). Because this type of electricity is typically not separately metered, NMED then uses other information, including EV registrations in an EDU’s service area and their EDU-specific CI values, to calculate “base” credits allocated to EDUs twice per year.
For more information about carbon intensities for electricity, please see Section 206 of the full-text CTFP rule.
July 2026 Tier 1 & 2 Carbon Intensity (CI) Calculators release and public input period: Organizations that apply for a New Mexico Alternative Fuel Pathway (AFP) will use these calculators to calculate CI values for their New Mexico Alternative Fuel Pathway applications.
- Once approved by NMED, Tier 1 or Tier 2 CI values become a part of their fuel pathway codes. Fuel pathway codes are unique identifiers used to allocate CTFP credit or deficit balances.
- The Tier 1 CI Calculators are based on NM-GREET, an adaptation of Argonne National Laboratory’s GREET (Greenhouse gases, Regulated Emissions, and Energy use in Technologies). They use simplified parameters for fuels that are conventionally produced and well-evaluated in New Mexico’s CTFP or similar clean transportation fuel programs.
- The Tier 2 CI Calculator is a standalone workbook that uses the full, unmodified NM-GREET lifecycle analysis for fuel production processes that are more complicated than can be accurately captured in Tier 1 CI Calculators.
NMED will collect public input on the Tier 1 CI Calculators through July 31. NMED’s Tier 2 calculator previously went through public review as a part of the CTFP rulemaking process.

To submit comments on Tier 1 CI Calculators:
- Visit our SmartComment portal here and click on “Clean Transportation Fuel Program – Provide Public Input on Tier 1 Carbon Intensity Calculators.”
- Follow SmartComment Commenter Instructions.
Please submit all comments by July 31, 2026. NMED will review comments and evaluate if feedback should be incorporated into a second version of the Tier 1 CI Calculators.
