Gasoline, diesel, bunker fuel, and jet fuel. Four liquid hydrocarbons that have been powering transportation for the last 100-plus years.

Gas stations, truck stops, ports, and airport fuel terminals have been built up over the last century to make transportation easy and reliable.

These conventional fuels release Greenhouse Gases (GHG) when they are used, and governments all over the world are working on plans to shift towards cleaner fuels in an effort to lower emissions and minimize the effects of climate change.

For passenger cars, it’s clear that electricity will be the cleaner fuel type, with most countries adopting electric vehicles (EVs), and in some cases, providing their citizens with incentives to make the switch.

While many articles have been written about EVs and the benefits that come along with them, they fail to look at the transportation system as a whole.

Trucks, cargo ships, and airplanes are modes of transportation that are used every day, but they don’t often get the spotlight like EVs do.

For governments to be effective in curbing transportation-related greenhouse emissions, they must consider all forms of transportation and cleaner fuel options for them as well.

43 percent of GHG emissions comes from these modes of transportation. Therefore, using electricity to reduce GHG emissions in light duty vehicles only accounts for part of the total transportation emissions equation.

The path to cleaner fuels for these transportation modes has its challenges.

According to Ed Emmett, Fellow in Energy and Transportation Policy at the Baker Institute Center for Energy Studies (CES);

  • "Airplanes cannot be realistically powered by electricity, at least not currently, and handle the same requisite freight and passenger loads"
  • "The long-haul trucking industry [...] pushed back against electrification as being impractical due to the size and weight of batteries, their limited range, and the cost of adoption"
  • "Shipowners have expressed reluctance to scrap existing bunker fueled ships for newer, more expensive ships, especially when other fueling options, e.g. biofuels and hydrocarbon derivatives-for fleets can be made available"

Finding low-cost, reliable, and environmentally sound fuels for the various segments of transportation is complex. As Emmett suggests in his latest article;

"Hovering over the transition to other fuels for almost every transportation mode is the question of dependability of supply. For the trucking industry, the truck stop industry must be able to adapt to new fuel requirements. For ocean shipping, ports must be able to meet the fuel needs of new ships. Airlines, air cargo carriers and airports need to be on the same page when it comes to aviation fuels. In other words, the adoption equation in transitions in transportation is not only a function of the availability and cost of the new technology but also a function of the cost of the full supply chain needed to support fuel production and delivery to the point of use. Going forward, the transportation industry is facing a dilemma: How are environmental concerns addressed while simultaneously maintaining operational efficiency and avoiding unnecessary upward cost shifts for moving goods and people? In answering that question, for the first time in history, modes of transportation may end up going in multiple different directions when it comes to the fuels each mode ultimately chooses."

This is why many forecasts predict that hydrocarbon demand will continue through 2050, despite ambitious aspirations of achieving net zero emissions by that year. The McKinsey "slow evolution" scenario has global liquid hydrocarbon demand in 2050 at 92mmb/d versus 103 mmb/d in 2023. With their "continued momentum" scenario, oil demand is 75 mmb/d. Proportionally, global oil demand related to GHG emissions from transportation would decline 11-27 percent. The global uptake of EVs is the primary driver of uncertainty around future oil demand. In all the McKinsey scenarios, the share of EVs in passenger cars sales is expected to be above 90 percent by 2050.

The Good News

Despite the relatively slow progress expected for reducing GHG emissions in the global transportation sector, there are solutions emerging that lower the carbon footprint tied to traditional petroleum-based fuels. Emmett highlights some of the methods under study, noting that "sustainable biofuels sourced from cooking oils, animal fats, and agriculture products, as well as hydrogen, methanol, ammonia, and various e-fuels are among the options being tested. Some ocean carriers are already ordering ships powered by liquified natural gas, bio-e-methanol, bio/e-methane, ammonia, and hydrogen. Airlines are already using sustainable aviation fuel as a supplement to basic aviation fuel. Railroads are testing hydrogen locomotives. The trucking industry is decarbonizing local delivery by using vehicles powered by electricity, compressed natural gas, and sustainable diesel. Long-haul trucking companies are considering sustainable diesel as a drop-in fuel for existing equipment, and fuel suppliers are researching new engines fueled by hydrogen and other alternative fuels."

Most of these options will require a combination of increased government incentives, along with advancements in technology and cost reductions.

McKinsey's "sustainable transformation" scenario, which considers potential shifts in government regulations as well as advancements in technology and cost, suggests there is moderate growth in alternative fuels alongside growth in EVs. Mckinsey projects;

  • EV demand could grow to over 90 percent of total passenger car sales by 2050
  • EVs to make up around 80 percent of commercial truck sales by 2050
  • In aviation, low carbon fuels such as biofuels, synfuels, hydrogen and electricity are projected to grow to 49 percent by 2050.

According to McKinsey, the combination of these alternatives along with demand changes in power and chemicals could reduce global oil demand to 60 mmb/d in 2050. The shift to cleaner fuels, for modes of transportation other than EVs, is underway but the progress and adoption will take decades to achieve according to McKinsey’s forecasts.

Looking more closely at EVs, the story may not be as dire globally as it seems to be in the West. While the U.S. appears to be losing momentum on electric vehicle adoption, China is roaring ahead. New electric car registrations in China reached 8.1 million in 2023, increasing by 35 percent relative to 2022. McKinsey’s forecasts have underestimated global EV sales in the past, with China surpassing their estimates, while the U.S. lags behind. It’s clear that China is the winner in EV adoption; could they also lead the way to adopt cleaner fuels for other modes of transport? That is something governments and the transportation industry will be watching in the years ahead.

Conclusion

While we are not on a trajectory to meet the aspirations to reduce global GHG emissions in the transportation sector, there are emerging solutions that could be adopted should governments around the world decide to put in place the incentives to get there. Moving forward, the future of transportation fuels will be shaped by a mix of innovation, government policies, and what consumers want. The focus will be on ensuring that the transportation sector remains reliable, secure, and economically robust, while also reducing GHG emissions. But, decarbonizing the transportation sector is much more than just EV's – it's a broader effort that will require continued global progress in each of the multiple transportation segments.

A View From HETI

U.S. LNG is essential to balancing global energy markets for the decades ahead. Photo via Getty Images

The debate over U.S. Liquefied Natural Gas (LNG) exports is too often framed in misleading, oversimplified terms. The reality is clear: LNG is not just a temporary fix or a bridge fuel, it is a fundamental pillar of global energy security and economic stability. U.S. LNG is already reducing coal use in Asia, strengthening Europe’s energy balance, and driving economic growth at home. Turning away from LNG exports now would be a shortsighted mistake, undermining both U.S. economic interests and global energy security.

Ken Medlock, Senior Director of the Baker Institute’s Center for Energy Studies, provides a fact-based assessment of the U.S. LNG exports that cuts through the noise. His analysis, consistent with McKinsey work, confirms that U.S. LNG is essential to balancing global energy markets for the decades ahead. While infrastructure challenges and environmental concerns exist, the benefits far outweigh the drawbacks. If the U.S. fails to embrace its leadership in LNG, we risk giving up our position to competitors, weakening our energy resilience, and damaging national security.

LNG Export Licenses: Options, Not Guarantees

A common but deeply flawed argument against expanding LNG exports is the assumption that granting licenses guarantees unlimited exports. This is simply incorrect. As Medlock puts it, “Licenses are options, not guarantees. Projects do not move forward if they are unable to find commercial footing.”

This is critical: government approvals do not dictate market outcomes. LNG projects must navigate economic viability, infrastructure feasibility, and global demand before becoming operational. This reality should dispel fears that expanded licensing will automatically lead to an uncontrolled surge in exports or domestic price spikes. The market, not government restrictions, should determine which projects succeed.

Canada’s Role in U.S. Gas Markets

The U.S. LNG debate often overlooks an important factor: pipeline imports from Canada. The U.S. and Canadian markets are deeply intertwined, yet critics often ignore this reality. Medlock highlights that “the importance to domestic supply-demand balance of our neighbors to the north and south cannot be overstated.”

Infrastructure Constraints and Price Volatility

One of the most counterproductive policies the U.S. could adopt is restricting LNG infrastructure development. Ironically, such restrictions would not only hinder exports but also drive up domestic energy prices. Medlock’s report explains this paradox: “Constraints that either raise development costs or limit the ability to develop infrastructure tend to make domestic supply less elastic. Ironically, this has the impact of limiting exports and raising domestic prices.”

The takeaway is straightforward: blocking infrastructure development is a self-inflicted wound. It stifles market efficiency, raises costs for American consumers, and weakens U.S. competitiveness in global energy markets. McKinsey research confirms that well-planned infrastructure investments lead to greater price stability and a more resilient energy sector. The U.S. should be accelerating, not hindering, these investments.

Short-Run vs. Long-Run Impacts on Domestic Prices

Critics of LNG exports often confuse short-term price fluctuations with long-term market trends. This is a mistake. Medlock underscores that “analysis that claims overly negative domestic price impacts due to exports tend to miss the distinction between short-run and long-run elasticity.”

Short-term price shifts are inevitable, driven by seasonal demand and supply disruptions. But long-term trends tell a different story: as infrastructure improves and production expands, markets adjust, and price impacts moderate. McKinsey analysis suggests supply elasticity increases as producers respond to price signals. Policy decisions should be grounded in this broader economic reality, not reactionary fears about temporary price movements.

Assessing the Emissions Debate

The argument that restricting U.S. LNG exports will lower global emissions is fundamentally flawed. In fact, the opposite is true. Medlock warns against “engineering scenarios that violate basic economic principles to induce particular impacts.” He emphasizes that evaluating emissions must be done holistically. “Constraining U.S. LNG exports will likely mean Asian countries will continue to turn to coal for power system balance,” a move that would significantly increase global emissions.

McKinsey’s research reinforces that, on a lifecycle basis, U.S. LNG produces fewer emissions than coal. That said, there is room for improvement, and efforts should focus on minimizing methane leakage and optimizing gas production efficiency.

However, the broader point remains: restricting LNG on environmental grounds ignores the global energy trade-offs at play. A rational approach would address emissions concerns while still recognizing the role of LNG in the global energy system.

The DOE’s Commonwealth LNG Authorization

The Department of Energy’s recent conditional approval of the Commonwealth LNG project is a step in the right direction. It signals that economic growth, energy security, and market demand remain key considerations in regulatory decisions. Medlock’s analysis makes it clear that LNG exports will be driven by market forces, and McKinsey’s projections show that global demand for flexible, reliable LNG is only increasing.

The U.S. should not limit itself with restrictive policies when the rest of the world is demanding more LNG. This is an opportunity to strengthen our position as a global energy leader, create jobs, and ensure long-term energy security.

Conclusion

The U.S. LNG debate must move beyond fear-driven narratives and focus on reality. The facts are clear: LNG exports strengthen energy security, drive economic growth, and reduce global emissions by displacing coal.

Instead of restrictive policies that limit LNG’s potential, the U.S. should focus on expanding infrastructure, maintaining market flexibility, and supporting innovation to further reduce emissions. The energy transition will be shaped by market realities, not unrealistic expectations.

The U.S. has an opportunity to lead. But leadership requires embracing economic logic, investing in infrastructure, and ensuring our policies are guided by facts, not political expediency. LNG is a critical part of the global energy landscape, and it’s time to recognize its long-term strategic value.
