Selecting the right fuels for your fleet

When it comes to managing a fleet of vehicles, one of the critical decisions you must make is choosing the right fuel. The current drive towards sustainability and cost-effectiveness has expanded the options for fleet fueling, including petrol, diesel, electric and several forms of hybrids, e-fuels, and alternative fuels and technologies. In this article, we will provide an overview of these different fuel types to help you make the right decisions for your fleet.

The Importance of Fuel Type Selection for your international fleet

1. Improve Fuel Economy

Did you know that the fuel consumption of your fleet can vary significantly depending on how and where the vehicles are driven? By carefully assessing your operations and selecting vehicles based on your specific needs, you can improve overall fuel economy, potentially saving you a lot of money annually.

2. Curb Emissions

Fleets are under increasing pressure to reduce emissions and adopt eco-friendly practices. Fun fact: By selecting the right fuel types, you can proactively reduce your fleet's emissions, demonstrating your commitment to sustainability. Plus, you might be eligible for government incentives and subsidies, which can further reduce your TCO.

3. Compliance with Legislation

Many cities have initiatives that encourage or discourage certain fuel types based on environmental performance. Staying informed about these regulations is essential. Complying with these regulations not only keeps you in the clear for fines but also promotes a positive public image for your organization.

4. Cost Savings

The total cost of ownership (TCO) for a vehicle goes beyond the monthly lease fee. It includes among others also fuel costs. Different fuel types can have a significant impact on TCO, so it's essential to assess these factors to make cost-effective choices that contribute to your bottom line.

Fuel Types; The Facts


Diesel vehicles were once popular for their fuel economy, thanks to their high power-to-weight ratio and energy density. However, things changed. Diesel vehicles emit 15% less CO2 than petrol but release more nitrogen dioxide (NO2) and particulate matter (PM), contributing to air quality issues. Some European countries are even planning to ban new diesel and petrol cars by 2030 from larger areas than merely cities.


Internal combustion vehicles still make up on average 95% of all personal cars and LCVs in Central Europe. They are not only cost-effective but also have high availability. They are often the least expensive option to purchase outright or lease, making them appealing for budget-conscious fleet managers.

On the downside, petrol vehicles emit about 15% more CO2 than diesel counterparts. This emission factor has been identified as a key contributor to climate change, making emission standards crucial, especially in urban areas.


Electric vehicles (EVs) are gaining popularity due to their low emissions and cost-effective charging. Here's an interesting fact: The cost-per-mile to fuel an EV represents approximately one-third to one-quarter the cost of petrol, making them highly economical for city driving.

While EVs are perfect for short journeys and city driving, they may not be the best choice for long-distance travel due to charging limitations. Notably, the charging infrastructure is continually evolving to address this challenge. Business Lease has developed a tool to analyze a fleet to determine which vehicle could change to a more economical sustainable powertrain.

Plug-in Hybrid

Hybrid vehicles combine the best of both worlds, offering reduced emissions and improved fuel economy. An exciting fact: They can cut emissions by 25 - 35% in average driving conditions, making them a fantastic choice for various driving needs. Additionally, there are tools available to ensure that a Plug-in Hybrid is utilized to its full potential.

Some hybrids may qualify for government financial incentives, adding even more appeal to the offer. Plus, their reduced maintenance requirements translate to less downtime and lower associated costs.


Several initiatives worldwide are in development with e-fuel production plans as a potential solution to extend the life of internal combustion engines beyond 2035, when Europe plans to phase them out. Recently the EU, on request of Germany, has excluded e-fuels from this deadline. E-fuels, such as e-methanol, are created through electrolysis of water and CO2, after transformation offering a 70% (on average) carbon-neutral alternative for traditional combustion engines.

The e-fuel industry is in its early stages, while e-fuels may offer a transitional solution for existing internal combustion engines, they come with inherent inefficiencies, resource-intensive production processes, and economic challenges. To demonstrate its viability and produce significant quantities and potentially preserve vehicles has not been a proven concept yet.

Alternative Fuels

The world of alternative fuels is continually evolving. It includes options like ethanol, biodiesel, natural gas (CNG, LNG), propane, hydrogen, flex fuel, and fuel cell technologies. Remarkably, some of these fuels are already in use, while others are in development or under conceptualization.


Selecting the right fuel for your fleet is a complex decision that requires careful consideration of various factors, including vehicle usage, location, frequency, and environmental impact. Ensuring that your choices align with regulations, cost-effectiveness, and your company's image is crucial. By taking the time to evaluate your options, you can make informed decisions that benefit your fleet's performance, reduce costs, and contribute to a more sustainable future.

Business Lease can help you do just that. We have developed an analysis tool for our customers and prospects to scan their fleets for possibilities to optimize fuel decisions and by doing so, improve the TCO and reduce carbon emissions.
