Corporate fleets across Europe are making measurable progress in cutting emissions and adopting cleaner technologies, but the pace of change varies significantly between sectors. The findings come from the second edition of the Fleet Sustainability Ranking Report, produced by Ayvens, a leader in sustainable mobility, which tracks how different industries are transitioning toward low- and zero-emission mobility across 29 European countries.
Across all sectors, the analysis shows clear and consistent progress. The average CO₂ emissions of a new fleet vehicle has dropped 25% since 2022, reflecting a sustained focus on low-emission transition. Diesel vehicles now represent less than a quarter of new fleet orders, compared with nearly half two years ago, while battery electric vehicles (BEVs) have increased their share across every industry, more than doubling in most cases. Hybrid and plug-in hybrid shares have remained broadly stable, suggesting a gradual but decisive shift towards more sustainable practice.
This year’s ranking builds on the 2022 edition and evaluates each industry across four equally weighted indicators: the share of diesel vehicles, battery electric vehicles (BEVs), plug-in hybrids (PHEVs) and hybrids, and the average CO₂ emissions of newly registered fleet cars. The industries analysed are:
-
Automotive
-
Construction
-
Consumer Goods
-
Energy & Chemical
-
Financial & Professional Services
-
Healthcare
-
Industrial
-
Pharmaceutical and Technology
By comparing results year on year, the study is now able to highlight which sectors are leading the transition and which are still delayed in making progress.
The Financial & Professional Services sector retains first place as the most sustainable industry for the second consecutive year, supported by the lowest diesel share and lowest average CO₂ emissions. The Construction industry ranks second, recording the strongest overall improvement since 2022, with BEVs making up 39% of new vehicles, the highest figure of any industry. In third place, the Energy & Chemical sector achieved the largest reduction in CO₂ emissions, down 30% since 2022.
Conversely, Healthcare remains the least sustainable industry. While diesel has declined, BEV uptake remains the lowest of all sectors, and the share of petrol vehicles has increased – suggesting that some fleets are switching away from diesel without fully embracing electrification. Industrial and Pharmaceutical fleets continue to rely on higher diesel shares than average, though both have halved their diesel use since 2022. Meanwhile, the Technology and Automotive sectors show steady progress, driven by higher hybrid adoption and continued BEV growth.
Reflecting on the report, Suzanne Phillips, UK Head of Specialist Sales at Ayvens said:
“What we’re seeing now is a real tipping point in corporate mobility. Two years ago, many companies were still testing the waters on electrification – now, across most industries, it’s become an operational and financial reality. The leaders in this year’s ranking aren’t just reacting to regulation; they’re proactively integrating sustainability into their business models, and that’s driving tangible progress.
The differences between sectors underline that this transition isn’t one-size-fits-all. Some industries, like healthcare or manufacturing, face very specific logistical and cost barriers that require tailored solutions. That’s where our work at Ayvens comes in – using data, fleet expertise and on-the-ground support to help businesses overcome those obstacles in a way that’s practical, scalable and commercially sound.
Fleet sustainability isn’t just an environmental ambition anymore; it’s a competitive advantage. The organisations that move early are building more resilient, efficient and future-ready operations, and that’s exactly what this ranking brings to light.”
