Neste MY Renewable Diesel - a B2B fuel pushing US fleets toward lower emissions

Neste MY Renewable Diesel is the kind of fuel you notice the first time you follow a refuse truck on a cool San Francisco morning: the exhaust smells less acrid, the plume looks thinner, and the driver said his fleet manager likes the quieter cold starts. This is not a lab prototype but a commercial B2B fuel made from 100% renewable raw materials that is already in use with US heavy-duty fleets from California to New York.

What Neste MY Renewable Diesel is

Neste MY Renewable Diesel is a hydrotreated vegetable oil (HVO) fuel produced from waste and residue raw materials, designed as a drop-in replacement for fossil diesel in compression-ignition engines. It is chemically similar to fossil diesel but has a higher cetane number and contains virtually no sulfur or aromatics, which can contribute to cleaner combustion and lower local emissions.

According to Neste, the fuel can reduce greenhouse gas emissions by as much as 75–95% over its lifecycle compared to fossil diesel, depending on the feedstock mix and calculation methodology. That claim is based on lifecycle assessments following European Union Renewable Energy Directive and California Air Resources Board approaches, and has been cited by customers including the City of Oakland and trucking companies using the fuel in municipal and regional fleets.

How fleets use it in practice

In the US market, Neste MY Renewable Diesel is primarily available in California and a handful of other states where low-carbon fuel standards or corporate sustainability programs make the economics workable. Trucking, bus, construction and municipal fleets have been early adopters, often switching existing vehicles from fossil diesel to Neste MY without hardware changes, because the fuel meets ASTM D975 diesel specifications when blended appropriately.

On the ground, fleet managers describe the transition as straightforward: existing storage tanks and dispensing equipment can typically handle the fuel, and drivers report that vehicles start reliably in cold weather and maintain similar power and torque compared to conventional diesel, thanks to the high cetane number and energy content. For example, Oakland’s fleet director Michael Hurley is quoted saying his city’s use of renewable diesel has reduced greenhouse gas emissions significantly while keeping operational performance intact.

Feedstocks, specs and emissions

Neste produces MY Renewable Diesel at several refineries, using predominantly waste and residue feedstocks such as used cooking oil, animal fats and other biogenic materials that do not compete directly with food uses. The company emphasizes that the product is certified and traceable according to applicable sustainability schemes, which matters for regulators and corporate buyers seeking to avoid indirect land-use change impacts.

From a technical perspective, the fuel’s paraffinic nature and high cetane number (often quoted around 70–90, versus roughly 40–55 for conventional diesel) can improve combustion efficiency and reduce particulate matter, hydrocarbons and carbon monoxide emissions in many engines, although actual results depend on engine technology and duty cycle. Field reports from European truck operators and US municipal fleets suggest cleaner diesel particulate filters and less visible smoke under heavy load.

US availability and pricing reality

For US customers, availability is still geographically limited. Neste MY Renewable Diesel is sold through selected distributors and truck stops in California and some neighboring states, often under long-term supply contracts tied to the state’s Low Carbon Fuel Standard credits. Pricing is typically at a premium to conventional diesel but partially offset by regulatory incentives, corporate sustainability budgets and marketing value for public-facing fleets.

One West Coast fuel buyer described paying more per gallon but seeing the cost difference narrowed considerably after factoring in LCFS credits, federal incentives and avoided reputational risk from high-emission operations. That trade-off is central to the US angle: Neste MY is not the cheapest diesel at the pump, but for fleets chasing ESG scores and contract requirements, the fuel can be justified as a compliance and brand tool as well as a carbon lever.

Competitors and engine maker views

Neste is not alone in renewable diesel. Other energy groups and refiners also offer fuels meeting EN 15940 paraffinic diesel specifications, and US refiners have added renewable diesel capacity in states like Louisiana and Texas. However, industry analysts often describe Neste as among the largest producers globally, with a strong position in waste and residue-based HVO and established distribution into Europe and North America.

Engine manufacturers, including heavy-duty diesel OEMs, have generally endorsed paraffinic renewable diesel as compatible with many modern engines, subject to regional standards and warranty terms. Official statements from truck makers and engine companies often note that HVO fuels can be used without modifications in approved engines, delivering lower emissions while maintaining performance, which gives Neste MY a credible technical foundation beyond its own marketing claims.

Climate targets and investor context

For Neste, MY Renewable Diesel is part of a broader transition from a traditional refining business toward renewable products, including sustainable aviation fuel (SAF) and feedstocks for polymers and chemicals. Chief Executive Officer Matti Lehmus has repeatedly highlighted renewable diesel and SAF volumes as core to the company’s growth strategy and decarbonization ambitions, linked to long-term targets for reducing customers’ emissions.

Revenue from renewable products, including Neste MY, contributes significantly to the company’s earnings mix, and capital expenditure has focused on expanding renewable refining capacity and supply-chain logistics in North America and Europe. While this article focuses on the fuel rather than the equity, Neste stock (HEL: NESTE, ISIN FI0009013296) is closely watched by investors as the company navigates policy changes, feedstock availability and competition in low-carbon fuels.
