Fleet electrification is accelerating across the U.S. and Canada. However, many operators still face the financial challenge of replacing diesel vehicles all at once. New vehicle purchases, charging infrastructure and downtime can delay adoption.
Renewable diesel, particularly hydrotreated vegetable oil (HVO), is becoming a practical near-term solution for fleets that want to reduce emissions now while building toward broader electrification. It helps operators meet sustainability targets without disrupting uptime.
Why Renewable Diesel Makes Sense for Fleets Right Now
For many medium- and heavy-duty fleets, electrification is still a phased process rather than an overnight switch. Renewable diesel supports that reality. It has a chemical composition comparable to conventional petroleum diesel, complies with ASTM D975 standards in the U.S. and can also be used either on its own or blended with traditional diesel fuel.
In practical terms, fleets can start decarbonizing immediately without waiting for new vehicles or charging infrastructure. Operators can deploy EVs where routes make sense, while using renewable diesel in the rest of the fleet to reduce emissions across the broader operation. This fuel source is a practical option for organizations seeking measurable progress as EV adoption continues to scale.
What Is HVO Renewable Diesel and How Does It Work?
HVO renewable diesel comes from renewable feedstocks, such as used cooking oil, vegetable oils and animal fats. Hydrotreating, which removes oxygen and impurities, converts those materials into a fuel that is chemically similar to conventional diesel. This high-quality fuel performs well even in cold weather.
HVO can work in existing diesel engines and storage systems without requiring major modifications, making it easier for businesses to lower greenhouse gas emissions while keeping current trucks, generators or off-road equipment in service. That drop-in compatibility is what makes renewable diesel so appealing to fleet managers.
[Ed. note: Renewable diesel is not biodiesel. Both may be derived from the same feedstocks, but biodiesel is created through a different process and the end result is not a “drop-in” fuel, but typically is blended in up to a 20% blend with petroleum diesel.]
How Renewable Diesel Helps Reduce Fleet Emissions
HVO renewable diesel improves environmental performance by reducing life cycle GHG emissions compared with fossil diesel. Under the U.S. Renewable Fuel Standard, EPA states that biomass-based diesel, including renewable diesel, must achieve a 50% reduction in GHG emissions relative to the diesel baseline.
That reduction is critical because liquid fuels still dominate transportation. In 2023, gasoline and diesel together accounted for nearly 80% of transportation sector carbon dioxide emissions in the U.S. While fossil-derived diesel will likely remain in heavy-duty use, incorporating renewable solutions can support near-term emission targets.
Consumer demand is helping accelerate the adoption of cleaner transportation choices. Research cites a 71% jump in searches for sustainable products among Gen Z and Millennials. For fleet operators, that signals growing pressure from customers and business partners to demonstrate meaningful progress on emissions reductions.
HVO Renewable Diesel as a Smart Fleet Decarbonization Strategy
For fleet managers, HVO renewable diesel is a smart complement to an EV strategy. It offers immediate emissions reductions and protects existing vehicle investments. HVO also creates a realistic path toward lower-carbon operations as electrification scales. For fleets that cannot wait for tomorrow’s infrastructure, renewable diesel delivers a practical transition today.
