Renewable natural gas (RNG) continues to gain momentum across the transportation sector as fleets look for practical ways to reduce emissions without disrupting operations. From heavy-duty trucking and transit to refuse fleets, RNG helps organizations achieve economic and environmental benefits through fuel cost stability and lower lifecycle emissions.

These themes were echoed throughout ACT Expo 2026, where the Kinder Morgan RNG team joined fleet operators, fuel providers, and technology leaders in Las Vegas, Nevada May 4–7, 2026, for conversations on the future of sustainable transportation.

Marking its 16th year in 2026, ACT Expo is one of North America’s largest events focused on advanced vehicle technologies and clean fuels, drawing more than 12,000 transportation stakeholders, 400+ exhibitors and sponsors, and 300+ expert speakers.¹

Across conversations with fleets, from early-stage evaluators to established RNG users, the message was consistent. RNG offers a rare combination of availability, cost effectiveness, and emissions reductions, making it one of the most practical decarbonization pathways.

As noted by Business Development Manager at Kinder Morgan RNG, Anita Doyle:



"ACT Expo continues to be one of the most important venues for understanding where the market is headed. What stood out this year is the growing recognition that RNG is not a future solution, it’s a solution fleets are deploying right now. The outlook for RNG remains strong. Organizations are looking for reliable, cost-effective ways to decarbonize, and RNG delivers on both fronts."



 

The 2026 State of Sustainable Fleets Report: What the Data Shows

Released at the 2026 ACT Expo conference by TRC Companies, the 2026 State of Sustainable Fleets Market Brief provides a technology neutral assessment of clean fleet adoption trends across the U.S. commercial transportation sector. The report is built on a survey of more than 200 fleet managers, combined with secondary market data and expert input, offering a comprehensive annual evaluation of natural gas, battery electric, propane, hydrogen, and diesel technologies.²

Several findings from the 2026 State of Sustainable Fleets Market Brief highlight the continued expansion of RNG within the natural gas vehicle market:
 

• Among CNG‑using fleets surveyed, 65% report using RNG, and those fleets estimate that RNG accounts for 78% of their natural gas fueling volume.³
• In the first three quarters of 2025, RNG accounted for 97% of all natural gas used in California transportation.⁴
• The Cummins X15N natural gas engine completed its first full year of commercial availability in 2025 and delivered cost savings compared to diesel.⁵ These cost savings are backed by a report demonstrating that 71% of fleets using the Cummins X15N natural gas engine saw these savings in their operations.⁶
• In 2025, California RNG offered a 301% lifecycle GHG reduction relative to diesel.⁷
• The report notes that RNG supply has grown dramatically over the past decade and continued its rapid expansion in 2025, with the industry opening its 500th RNG production facility within the same year.⁸
• State-level clean fuel standard programs remain active in California, Oregon, Washington, and New Mexico, with additional proposals under consideration in the Northeast and Midwest.⁹
