Renewing the fleet in the dark: diesel, electric or wait

Rinnovare la flotta al buio: diesel, elettrico o aspettare · Transport · Beginner

The case

Twelve of your thirty vehicles must be replaced within two years. New diesel is the proven choice, but your two main clients have announced zero-emission supply chain targets by 2030 and one has already added environmental criteria to its tenders. Electric costs 70% more, range covers only 60% of your routes, the charging network on your main corridor is announced but not built, and current incentives expire in eight months with no certainty of renewal. Waiting means keeping vehicles with rising maintenance and risking arriving last on both incentives and green tenders. How do you build the decision?

Dodici dei tuoi trenta mezzi vanno sostituiti entro due anni. Il diesel nuovo è la scelta collaudata, ma i tuoi due committenti principali hanno annunciato obiettivi di filiera a zero emissioni entro il 2030 e uno ha già inserito criteri ambientali nelle gare. L'elettrico costa il 70% in più, l'autonomia copre solo il 60% delle tue tratte, la rete di ricarica sulla dorsale che percorri è annunciata ma non c'è, e gli incentivi attuali scadono tra otto mesi senza certezza di rinnovo. Aspettare significa tenere mezzi con manutenzione crescente e rischiare di arrivare ultimo sia sugli incentivi sia sulle gare green. Come costruisci la decisione?
