Vending Machine Carbon Footprints: Compare the Same Life Cycle
When a supplier quotes a vending machine carbon footprint, ask what the number covers before using it to choose equipment. A life-cycle greenhouse gas estimate answers a different question from a daily electricity measurement. The model, assumed service life and operating schedule belong beside the result.
What does a published calculator actually include?
Evoca’s public Carbon Footprint Calculator describes a footprint as greenhouse gas emissions related to a machine across its full life cycle. In its Necta Impulse path, the user selects a machine model, enters an estimated lifespan in years and enters operational weeks per year.
The displayed result separates Raw Material, Manufacturing, Distribution, Use and End of life. It also shows a total in kgCO2e and the percentage contribution of each stage. This is a useful example of the information to preserve when reviewing a supplier estimate. It is an Evoca tool for the listed equipment, not an assessment of a WEIMI machine.
Keep the operating assumptions with the number
Save the exact model and version, lifespan input and operating weeks together with the result. The calculator’s result summary also displays an operating-hours condition. Check that summary rather than assuming the estimate represents the opening hours of your venue.
For a comparison between offers, ask each supplier to explain the operating schedule and service-life assumptions used. If those assumptions differ, request a comparison on an agreed basis or describe the difference explicitly. Do not present two totals as equivalent evidence merely because both use kgCO2e.
Read the stage breakdown before choosing an action
A total alone does not show where the modeled emissions occur. Ask for the contribution of materials, manufacturing, distribution, use and end of life, together with an explanation of the calculation boundary. A claim about lower operating electricity should be checked against the use stage and the stated assumptions; it does not by itself establish a lower whole-life footprint.
Ask whether transport, maintenance, replacement parts and the products sold are included or excluded. These are boundary questions for the supplier, not features established by the stage labels alone. Request the underlying report and any available methodology or verification statement before repeating a numerical reduction claim.
Keep energy evidence as a separate comparison
An energy test reports performance under defined test conditions. A life-cycle carbon estimate combines a different set of inputs and boundaries. Our vending energy test protocol guide explains why the measurement method also needs to match the equipment being compared.
Keep electricity figures, energy-label records and carbon-footprint documentation in separate fields in the purchasing file. A footprint result does not establish a particular energy-label grade, and an energy grade does not provide the complete life-cycle emissions figure.
What should go into a WEIMI enquiry?
Send the proposed machine type, country of operation, expected operating schedule and the environmental information your purchasing team needs. Ask which model-specific energy and emissions documents are available and which assumptions they use. Do not substitute another manufacturer’s calculator result for missing WEIMI evidence.
A useful comparison file identifies the model, functional basis, service-life assumption, operating schedule, included stages and report source. If a supplier cannot provide a comparable assessment, record the gap rather than inventing a saving. Get My Custom Quote.
