EU city bus market: electric powertrains pass majority in 2025
Market inflection: city buses flip to zero-emission
A structural shift in European urban transit became visible in 2025 when more than half of newly registered city buses used non-diesel powertrains, marking a step-change in fleet composition and procurement behaviour. Battery-electric buses took the bulk of new sales, fuel-cell buses recorded only single-digit market share and legacy alternatives—hybrids and gas—declined sharply. Policy impetus from the Clean Vehicles Directive accelerated tenders and provided clearer demand signals, while cities with centralized procurement or targeted fiscal support moved fastest.
The transition is uneven. Several smaller Member States and a number of large markets—notably the UK and Italy—registered particularly strong BEV new-sales shares, while a minority of states lagged despite hosting vehicle production hubs. Compliance with formal procurement-phase targets remains patchy in places, highlighting a gap between registration statistics and documented tender-based compliance.
Real-world operational experience and individual procurement decisions are already shaping technology trajectories. A recent collapse of a Polish hydrogen-bus supplier—leaving about twenty ordered vehicles undelivered and endangering subsidy commitments—illustrates delivery and commercial-risk exposures for hydrogen programmes. Comparative trials in Polish cities found hydrogen fleets faced higher fuel costs, more frequent fuel supply issues and lower availability than BEV counterparts. Separately, Zurich’s transit operator has cancelled follow-on framework orders and opened a roughly CHF 140 million tender for a large batch of battery-electric buses, citing persistent reliability and delivery problems with incumbent platforms. These episodes show buyers’ growing preference for mass-proven BEV platforms when network dependability is at stake.
Cost modelling reinforces this procurement tilt. Conservative ten-year, high-use models cited purchase-price estimates of roughly €235,000 for diesel, €610,000 for battery-electric buses and €750,000 for hydrogen buses; energy-cost assumptions produced per-kilometre energy figures near €0.40 for diesel, €0.21 for BEV and €0.74 for hydrogen. When capital, operating costs and monetised emissions were combined, net-present-value outcomes favoured BEV fleets strongly in urban duty cycles.
Supply-chain and systems effects are now the decisive constraints. The concentration of near-term demand into battery cells, electric driveline suppliers and depot charging equipment is creating orders for megawatt-scale chargers, transformers and grid reinforcements. Where hydrogen retains traction, it is locally driven by industrial strategy or niche duty profiles rather than broad commercial economics. Policymakers face a clear trade-off: spreading scarce procurement across alternative powertrains fragments order books and risks higher per-unit costs and stranded assets, whereas targeted aggregation on mature BEV platforms can speed deployment, raise fleet availability and lower lifecycle costs.
If the 2023–25 momentum persists—combined with tighter procurement rules and maturing OEM product lines—full zero-emission replacement of new city buses could be reached years ahead of prior expectations, compressing investment timelines and reshaping competitive dynamics in the supplier base. However, electrification will expose operational challenges: depot electrification, grid upgrades, high-power charging logistics and battery lifecycle management are now the critical gating factors, and unresolved issues in these areas could produce short-term service disruptions and concentrated material bottlenecks.

EU electric car prices fall as affordable models hit market; 2030 policy fight threatens parity
Average EV price in the EU fell by €1,800 in 2025 as affordable B‑segment models entered the market, accelerating price convergence with combustion vehicles. Proposed dilution of the 2030 CO₂ target could cut projected EV market share and raise average prices by roughly €2,300 by 2030, while complementary fleet mandates and local‑content rules would reshape where and how those volumes translate into on‑shore production — sometimes at a short‑term cost premium.
European Electric Truck Sales Surge After New CO2 Target
European zero-emission truck adoption accelerated after the July 2025 CO2 target, pushing electric share to a new high and shifting manufacturer leadership. Policy measures and frontrunner nations narrowed the technology gap with China but left global competitiveness dependent on faster industrial scaling.
Zurich transit authority launches CHF 140m electric-bus tender after repeated supplier reliability issues
Zurich’s public transport operator has opened a new competitive procurement worth about CHF 140 million to replace diesel buses after ongoing delivery delays and technical faults from current suppliers. The March 17, 2026 deadline invites global manufacturers and could accelerate a market shift toward large-scale integrators with proven fleet reliability.
Which automakers electrified fastest in the US in 2025?
In 2025, U.S. electrification progress was led by premium nameplates and several consolidated OEM groups — Cadillac, Audi and Porsche posted the highest BEV shares — while mainstream volume brands remained in the mid-single digits. Global competitive pressures (notably lower-cost, high-volume Chinese entrants), regional patterns showing availability and price trumping policy signals, and gaps in charging and used-vehicle markets all helped shape demand timing and point to where automakers and policymakers must focus to broaden adoption.
Transport & Environment: Ambitious EU fleets law could supply majority of carmakers’ 2030 EV demand
T&E finds an upgraded EU fleets mandate (around a 69% EV-only target and removal of PHEVs) would deliver roughly 57% of the electric vehicles carmakers need by 2030 and unlock up to 1.9M additional Made-in-EU EVs. Evidence from recent public-procurement shifts (city buses) and draft Industrial Accelerator Act content rules show that pairing a strong fleets mandate with localisation criteria and bridging finance is the realistic path to convert procurement volumes into sustained European production gains; without that package, supply-chain constraints and uneven national tax regimes will blunt the manufacturing upside.
Kenya’s electric motorcycles climb to 15.3% of new registrations in 2025
Electric two-wheelers captured 15.3% of new motorcycle registrations in Kenya in 2025, driven by rapid growth in both supply and buyer interest. The surge — from single-digit shares just two years earlier — signals a structural shift in urban mobility with measurable emissions and market implications.
Tesla Leads Cleaner EV Supply Chains as EU Rules Propel Change
A new industry leaderboard shows Tesla, Volvo and Ford leading measurable supply‑chain decarbonisation driven largely by EU battery rules, but accelerating global manufacturing shifts — from Chinese upstream scale to U.S. localisation incentives — and a two‑year delay to EU due‑diligence provisions mean the gains are conditional and politically fragile.
Battery breakthroughs redraw the map for maritime electrification
Rapid falls in battery costs and big gains in pack-level energy density mean many prior maritime electrification studies understate what is now feasible. Ports, buffering systems, and hybrid architectures—not cell chemistry alone—will decide whether short and medium sea routes go fully electric while deep-ocean legs remain hybrid.
