Geotab Reveals Major Fuel Wastage due to Congestion in Europe's Capital Cities
The recent study from Geotab has cast a glaring light on the significant financial implications of urban congestion across Europe's major cities. By analyzing data from connected vehicles throughout 2025, the report reveals a staggering loss of over 1.58 million liters of fuel due to stationary vehicles caught in traffic, costing fleets approximately €2.6 million in wasted standing time.
As fuel prices continue to soar, exacerbated by geopolitical tensions, the potential costs of idling could rise exponentially—a projection suggesting a figure near €3.6 million is on the horizon. This fuel wastage crisis isn't just monetary; it's also contributing to environmental degradation, as every liter consumed in idle mode ultimately adds to carbon emissions.
The European Urban Freight Efficiency Index highlights a sharp disparity in how congestion impacts these capitals. London, consistently ranked near the bottom for vehicular efficiency, suffers intensely from its notorious stop-and-go traffic. In fact, London was found to have the highest fuel consumption rate, with passenger vehicles averaging 15.60 liters per 100 kilometers—an alarming statistic that reflects nearly a two-and-a-half times increase compared to Paris. Of the fuel utilized in London, 13.6% is consumed while vehicles are idling in traffic, with commercial trucks contributing to an idling rate of 11.1% as well. The unique challenges presented by London's traffic, such as loading restrictions and bus lanes, further complicate fuel efficiency for commercial fleets.
Contrastingly, the study identifies Berlin as the city with the best fuel efficiencies, demonstrating less idle fuel wastage—only 8.5% for trucks and better overall traffic flow. Following closely, Amsterdam’s figures suggest that it successfully maintains lower passenger vehicle idling ratios at just 10.5%. Dublin presents a mixed bag of results, showcasing a similar idling issue for passenger vehicles as London but performing better for its trucks at 5.8%.
Interestingly, Rome and Madrid exhibit low truck idle rates at merely 2.8%. The analysis suggests that while traffic may be slow, it remains in motion, thereby reducing the overall idle fuel wastage. On the other hand, Paris, despite having predictable travel times, experiences the highest idle fuel wastage for trucks, pointing to a city where commercial vehicles are losing nearly one out of every five liters of fuel while stationary.
Edward Kulperger, Geotab's Senior Vice President for EMEA, underscores a crucial shift in understanding congestion. He stated that while traditional metrics focus on time loss, there's a need to recognize the financial and environmental costs associated with idling vehicles. The millions spent on wasted fuel translate not only into direct expenses but also into a larger ecological footprint.Beyond time lost, the burden of congestion manifests in both financial strain and environmental impact.
The methodology for the European Urban Freight Efficiency Index scores the cities on a 0 to 100 scale, based on traffic flow efficiency and congestion costs—ultimately revealing a deeper insight into urban logistics challenges faced by fleet operators. The first dimension, focusing on traffic flow, constitutes 75% of the score, with congestion levels, traffic-free windows, and journey time predictability as key factors. The second dimension assesses idling rates as a proxy for system inefficiency—higher ratios indicate greater levels of congestion and signal timing issues.
Geotab’s report paints a troubling picture that not only highlights the hidden costs behind urban traffic congestion but also provides valuable insights for companies aiming to navigate these challenges effectively. Fleet managers now, more than ever, need to harness data analytics and performance metrics to combat the rising tide of costs associated with inefficiencies. With Geotab’s extensive technological platform at their disposal, companies can strive for operations that are not only economically viable but also engage sustainably with their urban environments.
In summary, as urban congestion remains a foremost challenge for cities across Europe, the findings emphasize a pressing need for sectors reliant on transportation to adopt smarter, data-driven strategies that mitigate idle times and promote greater fuel efficiency.
