The Transport Project and its natural gas vehicle fleet and fueler members support a newly introduced bipartisan, bicameral bill that would create a $1.00-per-gallon tax credit for motor vehicles that use renewable natural gas (RNG).
“We are fortunate to have bipartisan, bicameral support in advancing the use of domestically produced RNG in commercial trucking,” said Daniel Gage, president of The Transport Project. “Getting this credit passed in this Congress will promote energy security, American jobs, and fuel cost savings for businesses.”
No other transportation fuel is as sustainable, adaptive, and competitive across all vehicle classes as RNG, according to the group, a national coalition of roughly 200 fleets, vehicle and engine manufacturers and dealers, servicers and suppliers, and fuel producers and providers dedicated to the decarbonization of North America’s transportation sector.
“Transitioning to RNG-fueled vehicles can save money and reduce emissions, and deploys new, affordable, cleaner, and compliant technology without delay and without compromising business operations,” said Gage on April 3. “More and more commercial fleets are discovering how allocating RNG as transportation fuel can help achieve more sustainable results immediately.”
U.S. Reps. Brian Fitzpatrick (R-PA) and Linda Sánchez (D-CA), along with U.S. Sens. Thom Tillis (R-NC) and Mark Warner (D-VA), on April 2 introduced the Renewable Natural Gas Incentive Act of 2025, H.R. 2596 / S. 1252.
If enacted, the bill would amend the Internal Revenue Code of 1986 to promote the increased use of RNG, reduce greenhouse gas (GHG) emissions and other harmful transportation-related emissions, and increase job creation and economic opportunity throughout the United States, according to the text of the proposal.
“Achieving American energy independence demands bold, forward-thinking solutions — and RNG is one of the most promising,” said Fitzpatrick, who sponsored H.R. 2596. “By cutting emissions and modernizing transportation across our supply chains, RNG delivers both environmental progress and economic growth.”
Specifically, the bill would authorize the tax credit for RNG used or sold as fuel for motor vehicles, motorboats, or aviation, and it would expand credit eligibility to certified blended RNG to maximize clean fuel adoption across industries, according to the lawmakers, who said the credit would remain in place through 2035 if the bill is enacted.
“Heavy-duty trucks and buses are major contributors to pollution, accelerating climate change and worsening public health problems,” Sánchez said. “Our tax credit will incentivize replacing outdated fleets with more sustainable alternatives, ensuring a healthier environment and a stronger economy without disrupting operations or increasing costs.”
Tillis, who sponsored S. 1252, pointed out that the bill is a smart investment in America’s energy independence and economic growth. “By expanding domestically produced renewable natural gas, we can reduce reliance on foreign energy and create good-paying jobs across the country,” he said.
Several members of The Transport Project also endorsed the measure.
Mike Kiely, UPS president of global government affairs, said the proposed bill supports the use of methane-reducing RNG and encourages clean, efficient transportation while building energy security in the United States. “RNG is a winning solution for UPS and the logistics industry,” he said.
Likewise, John Skoutelas, vice president of government affairs and legal at Waste Management Inc. (WM), said the company supports what he called a “thoughtful approach to investing” in natural gas vehicles and trucking fleets that are allocated RNG.
“WM is focused on working toward a more sustainable tomorrow through our action and investments to create a lower emission fleet,” said Skoutelas. “This piece of legislation is critical toward helping the heavy-duty vehicle sector shift away from diesel vehicles and transition to lower emission transportation fuel for a more sustainable future.”
“Because RNG captures harmful greenhouse gases at the source — like dairies and other agriculture facilities — and at the vehicle, it is rated the cleanest fuel in the world, many times cleaner than electric vehicles,” added Andrew Littlefair, CEO and president of Clean Energy Fuels Corp. “The bipartisan approach to this legislation demonstrates the win-win-win nature of RNG — reducing emissions with a very affordable U.S.-produced alternative fuel for fleets operating U.S.-made vehicles, while bringing economic development to rural areas and helping our farmers.”
