The top of the decision chain. Cost savings persuade a site manager; carbon, water and contamination exposure persuade a board. This calculator turns your MWE deployment into board-ready ESG evidence — tonnes of CO₂e avoided, litres of diesel and water saved, and spill remediation exposure contained — using DEFRA 2024 conversion factors.
Your Operation
M1 — Fuel Logistics (FuelBag)
External fuel deliveries no longer required because the FuelBag is refilled on a planned schedule and distributes on-site.
Machines no longer tracking across site to a fixed fuel point and idling in a queue — fuel goes to the machine instead.
M2 — Generator Elimination (WetBag Hydraulic)
Hydraulic drive runs off your excavator's auxiliary circuit — the separate pump generator is eliminated entirely.
M3 — Water Efficiency (DustBag)
A mist cannon uses ~300 L/hr against ~1,000 L/hr for an open hose — same suppression, 70% less water.
M4 — Spill Containment (PPG26 Bunding)
Every litre in a 110% bund is a litre that cannot reach ground or watercourse. EA remediation cases typically run £10k–£60k per incident.
