How much would EPC+ save your fleet? A new calculator tells you in under two minutes.
The question
For the past year, our clients have asked the same thing: what would switching to EPC+ actually save us? The answer always involved a financial model, a phone call, and a wait. Now there's a tool that gives an answer in under two minutes.
What the calculator does
The ECO Track Fuel Calculator estimates four key metrics for your fleet:
- Average annual savings from EPC+ (fuel cost reduction)
- Payback period (how long until the blender install pays for itself)
- 10-year net present value (NPV)
- Tonnes of CO₂-e avoided over the projection horizon
You provide three inputs: annual diesel volume, fleet composition (off-road vs. on-road percentage), and industry. The calculator does the rest.
It's designed for fleet managers and sustainability officers who need a directional answer fast. You don't need a spreadsheet. You don't need to wait for a proposal. You get a result in under two minutes.
How it works
The calculator's financial model is calibrated against the GreenTECH Fuel benchmark that Empire's sales team uses for real client proposals. Every headline metric matches that model to within 0.00% for the validation case (a 4.5 million litre per year operation).
The 4% diesel efficiency uplift used in the model sits inside the 2–5% range that GreenTECH cites publicly from independent testing. We've chosen the conservative end of that range to avoid overpromising.
Cost-of-capital assumptions vary by industry, drawn from KPMG's 2025–2026 capital cost study. This is a defensible third-party reference rather than a single in-house assumption. If you're in mining, construction, transport, or agriculture, the calculator uses the right discount rate for your sector.
For customers eligible to monetise emissions reductions under Australia's voluntary carbon market, the model includes the value of carbon credits using ACCU forward-curve pricing. For non-eligible customers, it treats carbon as a non-monetised co-benefit. This means the calculator doesn't promise carbon revenue to operations that can't access the market.
The model auto-shifts each year, so projections always cover the next decade rather than going stale.
What it doesn't do
The calculator is a directional estimate, not a binding quote. Actual savings depend on fuel quality, duty cycles, fleet composition, site-specific conditions, and maintenance practices. Empire's team validates assumptions during follow-up and refines the model to your specific situation.
We also don't expose internal model components — no “Pathway 1/2/3/4” naming, no specific WACC percentages, no internal threshold numbers. The calculator gives you the output; the methodology stays transparent but simplified.
What's next
ECO Track is the first in a series of decarbonisation-economics tools we're building for industrial WA. HVO100 renewable diesel, behind-the-meter renewable generation, and a Safeguard Mechanism scenario modeller are on the roadmap. Each will follow the same principle: defensible third-party assumptions, calibration against real client numbers, and no overpromising.
