Diesel Industry Statistics

Diesel Industry’s latest snapshot traces how 34.7% of US energy related CO2 emissions still come from transportation while European diesel demand slips by 2.3 million barrels per day in 2023 versus 2022, even as fleet rules tighten with Euro VI and Stage V. You will also see where demand is heading, from distillate and diesel dominance in global trade to the $215.6 billion marine fuel projection to 2030, and how aftertreatment performance benchmarks like 90 percent plus SCR NOx conversion and near 99 percent DPF particulate capture translate into the real cost and carbon tradeoffs fleets face.

01 Industry overview

The diesel industry at a glance

Diesel remains a major transport fuel, with global gasoil and diesel demand forecast at 29.0 million barrels per day in 2026, but supply tightness and vehicle electrification are reshaping the industry.

Market size
Global gasoil and diesel demand was 28.857 million barrels per day in 2025 and is forecast to reach 29.034 million barrels per day in 2026. In the United States, transportation-sector diesel consumption was approximately 2.94 million barrels per day in 2025.[91][93]
Forecast & CAGR
The IEA forecasts gasoil and diesel demand growth of 0.6% in 2026, up from 0.8% in 2025. This indicates near-term expansion rather than a high-growth market, with demand increasingly concentrated in non-OECD economies.[91]
Market share & regions
Europe remains highly diesel-dependent in road transport: gas oil and diesel oil represented 63% of EU road-transport fuel use in 2024. The IEA reported that non-OECD countries accounted for the entire increase in global oil demand in its 2026 outlook, indicating that emerging markets are the principal source of diesel-demand growth.[92][91]
Segmentation
Diesel demand is segmented primarily by road transport, non-road equipment, marine uses, rail, power generation and heating. In the United States, transportation accounted for about 75% of total distillate consumption in 2025, while diesel is also widely used in trucks, trains, boats, agricultural machinery and construction equipment.[93]
Pricing
The U.S. Energy Information Administration forecast average U.S. retail diesel prices of $5.07 per gallon in 2026 and $4.40 per gallon in 2027. EIA attributed elevated prices to tight global distillate supply, reduced refinery activity abroad and low inventories.[93]
Trends, drivers & challenges
The market is being supported by freight, agriculture, construction and industrial activity, but challenged by refinery outages, geopolitical disruption, low inventories and the gradual substitution of diesel passenger vehicles. EIA forecast U.S. distillate inventories to remain below the five-year seasonal range through the end of 2026 and most of 2027.[93][92]
Consumer behavior & competition
Passenger-car demand is moving away from diesel in Europe: across 20 EU countries covering 93% of 2024 EU registrations, diesel-powered new-car registrations fell 67% between 2014 and 2024, while battery-electric registrations reached 13.9% in 2024. Competition is therefore shifting toward petrol hybrids, battery-electric vehicles, renewable diesel and other lower-emission fuels.[92]
M&A
Refining consolidation continued in 2025: Phillips 66 agreed to acquire Cenovus Energy’s remaining 50% interest in WRB Refining for $1.4 billion, gaining full ownership of the Wood River and Borger refineries. The company expected approximately $50 million in annual operating and commercial synergies.[51]
Regulation
U.S. heavy-duty emissions standards apply more stringent requirements from model year 2027, covering diesel engines and vehicles and extending the period over which standards must be met. EPA also states that nearly all on-road diesel trucks and many non-road machines have used diesel exhaust fluid with selective catalytic reduction since 2010.[82]
Latest news
In November 2026, Associated Press reported that tankers carrying Russian diesel changed course, raising uncertainty over potential shipments to the United States. The development illustrates how sanctions, shipping decisions and geopolitical risk continue to affect diesel supply and prices.[94]
