Customer Case Story:
Rapid Fleet Decarbonization for a European Parcel Delivery Leader

The Customer

The client is one of Europe’s leading international courier, express, and parcel delivery networks. Operating across an extensive regional network of distribution depots and last-mile pickup and delivery operations, the company has set an ambitious target to achieve Net Zero carbon emissions.

Key environmental initiatives across their logistics network include:

  • Transitioning urban delivery vehicles to zero-emission electric fleets.

  • Deploying low- and zero-emission heavy transport trucks on linehaul routes.

  • Building out EV charging infrastructure across national logistics depots.

  • Measuring, tracking, and reporting Scope 1, 2, and 3 Greenhouse Gas (GHG) emissions

To support our ambitious fleet decarbonization goals, we needed to move away from error-prone, rigid spreadsheets. We required a single source of truth that could centralize our fleet and depot metrics and deliver rapid business wins without massive implementation costs.

The Challenge

To execute its decarbonization roadmap, the logistics provider faced severe operational and data management hurdles:

  • Data Silos & Rigid Spreadsheets: Essential fleet, fuel, and depot operational data were trapped across fragmented spreadsheets and manual tour logs.

  • High Operational Friction: Logistics and operations teams spent hundreds of manual hours cleaning data, calculating emissions, and attempting to map vehicle usage.

  • Complex Fleet Decarbonization: Managing subcontracted last-mile drivers, route distances, and charging point readiness required a flexible solution capable of handling complex logistics data.

  • Frequent Disclosure Demands: The local network was burdened by frequent, non-standardized periodic reporting requests from central corporate management, commercial clients, and regulatory bodies.

The Solution

Instead of undergoing a long, expensive enterprise software procurement, the client partnered with Sustaira to deploy a tailored Sustainable Fleet Management Solution within days.

Sustaira leveraged its agile technology stack, combining pre-built, out-of-the-box functionality with rapid configuration, to deliver custom logistics capabilities:

  • Custom Sustainable Fleet Management App: Centralized tracking for electric vehicles (EVs), low-emission trucks, weight classes, depot locations, and charging infrastructure.

  • Automated Data Integration: Automated data ingestion from depot census logs and tour kilometer metrics, replacing manual spreadsheet math with reliable calculation logic.

  • Rapid Proof of Concept (PoC): Sustaira built and demonstrated a fully functional fleet management system in just two rapid iterations totaling 40 development hours.

  • Configurable Report Builder: Custom reporting templates that automatically compile operational fleet data into standardized corporate disclosures.

Sustaira gave us an actionable fleet management platform in a matter of days. By choosing an agile solution over rigid legacy processes, we instantly gained clear insights into our fleet electrification progress and empowered our team to drive real decarbonization.

The Results

By prioritizing agility over rigidity, Sustaira delivered quick proof of concepts and high-impact business wins while eliminating the overhead of enterprise software deployments:

  • Speed to Value: Delivered a working custom fleet solution in days through a 40-hour Proof of Concept.

  • Centralized Decarbonization Hub: Replaced siloed Excel files with a secure online fleet management platform.

  • Automated Disclosures: Eliminated manual reporting overhead by automating periodic disclosures for corporate headquarters.

  • Real-Time Fleet Dashboards: Provided 24/7 visibility into EV rollouts, charging point availability, and planned vs. actual progress.

  • Flexible Logistics Architecture: Established an agile foundation that continuously adapts as fleet requirements, route logistics, and decarbonization targets evolve.
