Do you know how green your fleet is? A practical guide to measuring fleet sustainability
Why measurement is the starting point for meaningful change
The shift toward electric and low-emission vehicles is well underway across Australia but the most successful transitions begin with data. Before introducing new vehicle types or charging infrastructure it is essential to understand your current fleet’s environmental impact and to measure progress over time.
A clear view of your fleet’s carbon footprint allows you to:
• Identify the highest emitting vehicles in your operation
• Prioritise replacement or offset opportunities
• Establish realistic sustainability targets aligned with your organisation’s goals
Mapping your baseline emissions
To make informed fleet decisions you first need to quantify where you stand. Interleasing provides clients with detailed CO₂ emission data for each vehicle type, comparing this information with national benchmarks such as the Australian Government’s Green Vehicle Guide (GVG).
The GVG is an invaluable resource that outlines:
• Tailpipe CO₂ emissions (grams per kilometre)
• Fuel lifecycle emissions accounting for production and use
• Energy consumption and electric range for EVs and hybrids
• Air pollution standards for each vehicle model
Using these metrics, fleet managers can identify quick-win opportunities such as replacing older internal combustion models with newer more efficient equivalents or piloting hybrid and electric options where duty cycles allow.
Building an evidence-based transition plan
At Interleasing our transition planning framework helps organisations move from measurement to implementation. This approach combines operational data with financial and behavioural insights to create a roadmap that balances sustainability, cost and driver adoption.
Typical steps include:
1. Assessing your current position – emissions profile, utilisation rates and driver behaviour patterns.
2. Evaluating vehicle and infrastructure options – understanding market availability, range capability and charging requirements.
3. Modelling your transition timeline – integrating procurement, leasing and replacement cycles into a staged implementation plan.
This method enables a structured and commercially practical path to a lower emission fleet.
Tracking progress and reporting results
Once a baseline is established, organisations can introduce measurable sustainability goals such as grams of CO₂ per kilometre or percentage of electric kilometres travelled and monitor improvements year on year. Interleasing’s analytics dashboards and reporting tools support continuous improvement and transparent sustainability reporting.
By tracking actual vehicle use and energy consumption you can demonstrate credible progress toward ESG and net-zero objectives while building a case for further investment in electrification.
Partnering for a sustainable future
Reducing emissions is only one part of the picture. Interleasing works with clients to help ensure the long-term sustainability of their fleet operations from procurement and financing to offsetting unavoidable emissions through reputable carbon programs such as Greenfleet.
