How a Food and Beverage Manufacturer Turned Customer Carbon Pressure Into Verified Savings
When a large retail customer sent its supplier a carbon questionnaire, the request landed on a plant manager who had never been asked for this kind of data before. The manufacturer, a mid-size food and beverage producer running one large plant and two smaller sites, had spreadsheets full of utility bills and fuel invoices but no real carbon inventory. The customer wanted numbers that would hold up. Leadership wanted a path that did more than answer one questionnaire. This is an illustrative account of how a producer in that position used EnergyOS to build a defensible carbon picture, prove savings on a planned retrofit, and improve its electricity footprint in a way a customer would trust.
The takeaway: a credible carbon program is not a one-time report. It is an inventory you can stand behind, savings you can verify, and an electricity number you can improve on purpose.
The operator and the customer pressure
The producer makes packaged foods across three facilities. The flagship plant carries most of the volume and most of the energy load, with gas-fired boilers driving process heat and the grid supplying everything else. The two smaller sites handle finishing and cold storage. For years the energy conversation lived inside monthly bills and the occasional budget review.
That changed when the retail customer folded carbon reporting into its supplier scorecard. The ask was specific. Report Scope 1 and Scope 2 emissions by site, show your methodology, and describe what you are doing to reduce them. A weak or hand-waved answer risked the account. The plant manager and the finance lead agreed on one thing quickly. They did not want to guess.
The challenge
Three problems sat on the table at once. First, there was no carbon inventory. The company burned natural gas in boilers and ovens and pulled power from the grid, but nobody had translated fuel and kilowatt-hours into emissions using a method a customer or auditor would accept. Second, a boiler and controls retrofit was already on the drawing board, and the capital plan leaned on financing that hinged on proven energy savings. A lender wanted evidence, not a vendor brochure. Third, leadership wanted to improve the electricity number in a way that was honest and documented, not a vague claim about buying green power.
Each problem needed a different tool. Together they needed one system that could hold the data, the method, and the paper trail in the same place.
Building the carbon inventory
The first job was Scope 1. Using EnergyOS, the team built a registry of combustion sources across all three sites: the process boilers, the ovens, and the smaller gas-fired units. Each source was tied to its fuel, and fuel consumption came in from meter reads and delivery records. EnergyOS applied EPA emission factors to convert that fuel use into carbon dioxide equivalent, with room for manual fuel entries where a source was not yet metered. The result was a Scope 1 figure grounded in a recognized factor set rather than a rough estimate, aligned with GHG Protocol accounting.
Scope 2 came next, and here the platform produced two numbers on purpose. The location-based figure used eGRID subregion factors to reflect the average emissions of the grid each site draws from. The market-based figure reflected the specific instruments the company held or would acquire. Building both is standard GHG Protocol practice, and having them side by side gave leadership an honest baseline before any green claims entered the picture.
With per-site snapshots in place, the company could hand its customer a breakdown by facility rather than a single blended total. That level of detail is exactly what a serious supplier questionnaire is looking for.
The retrofit and M&V
The boiler and controls upgrade promised real fuel reduction, but a promise does not unlock financing. The lender wanted savings that were measured, not modeled from a spec sheet. This is where EnergyOS ran a measurement and verification project.
The team established a baseline period from the plant's pre-retrofit operating data and weather-normalized it, so that a warm month or a cold snap would not distort the comparison. Following IPMVP-style method, the reporting period after the retrofit was measured against that normalized baseline. The output was a savings figure that accounted for weather and production swings, which meant the number reflected the equipment change rather than a mild winter.
For a food and beverage plant, where process heat tracks closely with both outdoor conditions and production volume, that normalization matters. Without it, a lender is right to be skeptical. With it, the savings claim carried the kind of evidence that supports a financing decision. In illustrative terms, verified fuel savings in the range typical of a boiler and controls project, often in the low double digits as a percentage of process fuel, gave the lender the documented result it needed.
Certificates and market-based Scope 2
Improving the electricity number called for care. Leadership did not want a claim that would embarrass the company under scrutiny. The location-based figure would always reflect the physical grid, and that stayed on the books untouched. The market-based figure was where energy attribute certificates came in.
EES brokered the procurement of certificates on the company's behalf, then used EnergyOS to hold them in inventory and allocate them per site. Because the allocation was explicit and documented, the market-based Scope 2 number could show a credible reduction tied to specific instruments, not a blanket assertion. The customer could see which site the certificates applied to and how the market-based total was built. That transparency is what separates a defensible green claim from greenwashing.
The results
The producer delivered supplier-grade carbon data to its retail customer, with Scope 1 and Scope 2 broken out by site and a methodology it could explain. The retrofit savings were verified against a weather-normalized baseline, which gave the lender the proof it wanted and kept the capital project on track. The market-based Scope 2 figure showed a credible reduction backed by allocated certificates. And because EnergyOS submeters by line and major equipment, the plant gained energy-per-unit visibility on its production lines, turning carbon work into an operational lever rather than a compliance chore.
These figures are illustrative and directional. The point is the pattern. When the inventory, the verification, and the certificate accounting live in one platform, each result reinforces the others. The customer trusts the data because the method is visible, the lender trusts the savings because the baseline is normalized, and leadership trusts the electricity claim because the certificates are allocated and recorded.
Closing
Supplier carbon pressure is not going away, and the plants that handle it best treat it as a chance to see their operations more clearly. A registry of combustion sources, a dual Scope 2 view, verified retrofit savings, and honestly allocated certificates add up to a program a customer, a lender, and a sustainability team can all stand behind.
