Carbon accounting for food and beverage: measure Scope 1, 2 and 3 from data you already have

Last updated July 2026. US food and beverage companies face emissions requests from every side: California SB 253 pulls in companies over $1 billion in revenue doing business in the state, grocery and foodservice customers push supplier questionnaires onto the brands they carry, and investors expect a credible footprint. A food business already generates most of the data an inventory needs. Utility bills for plants and cold storage, refrigerant service logs, fleet and freight invoices, and the accounts payable file that lists every ingredient, packaging line and co-packer you paid are the raw inputs, and our carbon accounting software classifies them into a scope-by-scope inventory with the evidence attached.

A food or beverage company's footprint splits across the three scopes in a way that decides where the data comes from. Scope 1 is direct emissions you own: natural gas for boilers, ovens, pasteurizers and process heat, owned distribution-fleet fuel, and refrigerant leakage from cold storage and processing, which is often a larger line than the fuel. Scope 2 is the purchased electricity that runs plants, cold storage and offices. Scope 3 is everything upstream and downstream, and for nearly every food and beverage company category 1, purchased goods and services, dominated by agricultural ingredients, is the overwhelming majority of the footprint.

The ingredient line is where food and beverage carbon accounting is decided. Because agricultural inputs usually carry the large majority of the footprint, a coarse spend-based screen over your Scope 3 reporting tells you which commodities to focus on, dairy, meat, grains, before you spend a season chasing farm-level data across every supplier. The full procedure, with the EPA factors, is in our guide to calculating Scope 3 from spend.

Agricultural emissions are hard because they come from biological processes, methane from livestock, nitrous oxide from fertilized soils, and land-use change, which vary enormously by product, region and farming practice and are poorly captured by a single spend factor. That is why food and beverage inventories screen with spend-based factors first to find the material commodities, then graduate those specific ingredients to supplier or commodity-specific data. Starting with the whole ingredient list at farm-level detail is how these projects stall; starting with a spend screen is how they finish.

Increasingly, yes. A US food or beverage company over $1 billion in revenue that does business in California must report Scope 1 and Scope 2 under SB 253, with a first deadline of November 10, 2026 and Scope 3 following in 2027. Below that threshold, the pressure usually arrives as a grocery or foodservice customer's supplier questionnaire: the big chains report their own Scope 3 and push data requests onto the brands they stock. Either way the deliverable is a defensible Scope 1, 2 and 3 number with evidence behind it, which is why building the inventory from your own records now pays off whichever request lands first.
