As companies navigate a business landscape defined by continuing disruption and uncertainty, decarbonization’s dual value of climate mitigation and long-term enterprise and financial resilience ensures it remains a business imperative. Indeed, few other corporate actions can simultaneously cut costs, open new markets, increase access to finance, reduce regulatory exposure, and bolster energy security.
This second blog in our three-part series on operational decarbonization explores how companies can use tailored fleet management to reduce their emissions while also bolstering operational performance. As with our first blog on industrial heat, we highlight real-world case studies to bring fleet decarbonization to life and highlight its unique challenges and opportunities.
Companies can drive significant reductions in both greenhouse gas (GHG) emissions and fuel costs through a focus on vehicle fleets (e.g., route optimization, electric vehicle adoption, alternative fuels, etc.). While exact solutions will vary by organization and jurisdiction, companies can develop tailored, value adding fleet decarbonization approaches with the right expert diagnosis.
For companies with large vehicle fleets, addressing transportation emissions is crucial to meeting sustainability goals. Still, the task can appear daunting. High upfront capital costs, significant operational impacts, and policy uncertainty often challenge companies and can slow progress. In the U.S., for example, the recent sunsetting of federal tax credits for electric vehicles will likely complicate corporate fleet management strategies that involve alternative fuel vehicles, although fleet/route optimization strategies remain value accretive. By contrast, in Europe and elsewhere, total cost of ownership (capital cost plus long run operating costs) of electrifying passenger car and van fleet can deliver impressive ROI. In one ERM project example, a pan-European manufacturing firm saw a 2.7 year payback through shift from diesel vehicle ownership to electric vehicle leasing.
Many of ERM’s clients also have fleets that span vehicle types which serve different purposes. Their fleet situations are further complicated because their vehicles are distributed across geographies and are at different stages of their useful asset life. Faced with these complexities, businesses struggle to identify a starting point for addressing fleet emissions.
Businesses can cut through these challenges by developing a strong fleet decarbonization strategy that breaks a fleet into component parts and identifies solutions for each, rather than pursuing a single, fleet-wide solution. For example, public incentives and low electricity prices in a given operating region might make certain fleet segments—such as light-duty vans or refrigerated trailers—well-suited for electrification, driving rapid financial upside.
Conversely, electrification in other fleet segments may be challenged by capital limitations, leading businesses to turn to renewable fuels that do not require significant infrastructure investment to achieve emissions reductions. Here, a “yes, and” approach enables more practical, scalable progress than an “either, or” approach.
The case studies we outline below exemplify how businesses have successfully applied this philosophy to reduce their fleet emissions.
To get started on fleet decarbonization, consider the following practical steps and read on to see how real-world companies are putting them into action.

Decarbonization is a clear strategic imperative for companies looking to improve operational resilience and financial performance. Whether by reducing operational costs, guarding against energy price volatility, or enhancing brand reputation, operational emissions reductions can deliver broad business value.
Using lessons learned from the case studies above, companies with large vehicle fleets can turn decarbonization from ambition to actuality, reaping benefits along the way.
