Use Sustainability as a Competitive Advantage

Sustainability initiatives are often driven by regulatory requirements and emission reduction goals, but the fleets making the most progress are connecting sustainability to efficiency, cost control, equipment strategy, customer expectations and long-term business resilience.

Many sustainability initiatives can improve how fleets operate and create real, measurable value by improving fuel efficiency, eliminating unnecessary idling and reducing wasted miles, which is why sustainability is increasingly becoming a competitive advantage. Fleets that take a practical, data-driven approach can reduce waste, control operating costs and help their customers make progress toward emissions goals.

Start With Efficiency

For most fleets, the highest-return sustainability opportunities begin with day-to-day efficiency. Reducing fuel use, eliminating unnecessary idling, improving routing and keeping equipment operating at peak performance can all lower emissions while improving the bottom line.

Fuel remains one of the largest operating expenses for fleets, and even incremental improvements in miles per gallon can create meaningful savings. Driver behavior is one of the most important variables. Hard acceleration, excessive speeds and unnecessary idling can reduce fuel economy, but consistent coaching and visibility into performance can help support better habits.

Equipment specifications can also make a difference. In long-haul operations, aerodynamics play an important role because drag becomes a significant factor at highway speeds. Side skirts, trailer gap reducers, boat tails, low-profile mirrors and other aerodynamic features can help reduce energy demand and improve fuel efficiency.

Maintenance is another critical part of the sustainability equation. Underinflated tires increase rolling resistance and can reduce fuel economy by 0.5 to 1% for every PSI below the recommended level. Air leaks can cause compressors to run more often. Poor battery maintenance can make alternators work harder. Dirty or restricted air filters, worn belts, improper belt tension, dragging brakes and cooling system issues can all affect efficiency, reliability and fuel economy.

Use Data To Uncover Opportunities To Improve

Data is essential to identifying where sustainability initiatives will have the greatest impact and quantifying actual gains. Many organizations already have access to information about fuel use, maintenance events, idling and more, but the challenge is turning that information into clear, actionable insights.

Advanced analytics and artificial intelligence can help fleets identify specific opportunities for improvement. Benchmarking performance against similar operations can reveal where a fleet is doing well and where there may be gaps, while visibility into maintenance and fuel trends can help pinpoint vehicles, locations, routes or behaviors that are driving unnecessary costs or emissions.

Penske’s Catalyst AI™, available through the Fleet Insight™ platform, is designed to help fleets make better use of their operational data. By benchmarking performance and identifying opportunities related to fuel efficiency, maintenance and utilization, fleets can better understand where targeted improvements may deliver the most value.

Utilization is especially important. When fleets can move the same amount of freight with the right mix of equipment, they may be able to add capacity, improve productivity and reduce costs without adding drivers or vehicles. Better utilization can also support sustainability by helping companies avoid wasted miles.

Deploy Alternative Fuel Vehicles in the Right Applications

Alternative-fuel vehicles are an important part of the sustainability conversation, but adoption needs to be determined by how well the vehicles can fit into a fleet’s overall operations and routes. Battery electric vehicles, compressed natural gas, renewable fuels and other solutions each have different strengths and limitations. There isn’t a one-size-fits-all approach, and the right answer will vary by application.

Battery electric vehicles, for example, may not be the right solution for every fleet application today, particularly in operations with long routes, heavy payloads, limited dwell time or uncertain charging access. However, they are proving valuable in specific duty cycles, including return-to-base operations, urban delivery, predictable routes, yard operations, short regional routes and applications with reliable charging access.

According to the 2026 State of Sustainable Fleets Market Brief, electric vehicles can offer lower energy costs, reduced routine maintenance and zero tailpipe emissions in the right application. The business case depends on several variables, including acquisition cost, electricity rates, demand charges, charging infrastructure, available incentives, route length, payload requirements and dwell time.

For many fleets, light- and medium-duty equipment that travels shorter distances and returns to base daily can be a practical entry point. Yard tractors can also be a strong place to start because they operate in defined areas, travel fewer miles and typically return to a central location where charging can be managed.

Penske Fleet Lab gives fleets a way to evaluate alternative-fuel vehicles on their own routes with support around vehicle selection, infrastructure, maintenance and performance monitoring. Pilots can help fleets determine where the technology works, what changes are needed and whether the application can scale.

It can also be useful for fleets to rent or lease alternative fuel vehicles to test the technology before making a long-term commitment. Penske has a wide range of battery electric vehicles available.

Sustainability Can Support Customer Growth

Sustainability is also becoming a more important factor in shipper and customer relationships. Many companies are tracking supply chain emissions, setting sustainability targets and asking transportation providers to share credible data about their efforts to reduce carbon emissions.

Fleets that can document fuel savings, emissions reductions, utilization improvements, renewable fuel use or alternative-fuel adoption may be better positioned to compete for that business. In some cases, sustainability performance can become a differentiator in bids, contract renewals and long-term customer partnerships.

Sustainability can also create new business opportunities. A fleet that can offer proven, lower-emission transportation solutions may be able to support customers with specific sustainability requirements, low-emission delivery zones, carbon reporting needs or compliance documentation.

Build a Short-, Mid- and Long-Term Roadmap

There is no single path to lower emissions. The most effective strategies often layer short-term initiatives that can create immediate benefits with mid- and long-term investments.

In the near term, fleets can focus on efficiency, renewable fuels, newer equipment and route optimization. Renewable diesel, for example, can be used as a drop-in solution in diesel engines. Penske currently offers R-99, a 99% renewable diesel fuel, at multiple West Coast locations.

Transitioning to late-model equipment can also improve fuel efficiency, since newer vehicles typically benefit from advances in engine technology, aerodynamics, emissions systems and safety features. The National Private Truck Council’s 2025 Benchmarking Survey found that fleets that lease all of their equipment operate newer vehicles, with an average equipment age of 3.2 years, compared with 5.34 years for fleets that own most of their equipment. As a result, leased fleets have a fuel economy of 7.24 miles per gallon compared to 5.84 mpg by fleets that own most of their equipment.

Reducing unnecessary miles, eliminating out-of-route miles and improving load planning can produce near-term emissions reductions.

Many mid- and long-range strategies often require more planning and investment. Fleets may evaluate opportunities to phase out older, less efficient equipment, deploy alternative-fuel vehicles, develop charging or fueling infrastructure and train drivers and technicians.
