The Industry Hotspot: Refrigerant Leakage and Upstream Products

Refrigerants and products dominate

Food retailers face emissions from two dominant sources. Refrigeration systems in stores and distribution centers use hydrofluorocarbon refrigerants with very high global warming potential. Equipment leakage rates vary by system type and maintenance practices with older systems showing higher losses. Walk-in coolers, display cases, and refrigerated warehouses contain substantial refrigerant charges. Upstream product emissions dwarf operational footprint representing sold product manufacturing, agricultural production, and packaging. Retailers influence supplier emissions through procurement policies and sustainability programs. Building energy for HVAC and lighting varies by climate zone and building efficiency. NetNada tracks refrigerant type and leakage by location, calculates building energy per square meter, aggregates upstream product footprints from supplier data, and reports food waste by disposal method.

SASB Industry Definition

Refrigerant Leakage Tracking

Supermarkets operate numerous refrigeration systems including walk-in coolers, display cases, ice machines, and refrigerated prep areas. Each system contains refrigerant charge that leaks over time through connections, seals, and component failures. Track refrigerant type by location with older systems often using high-global-warming-potential hydrofluorocarbons. Monitor annual refrigerant additions indicating leakage rates. Implement leak detection and repair programs reducing losses. Calculate emissions by applying global warming potential factors to refrigerant mass lost.

Leakage rate per location

Store Energy Per Square Meter

Retail stores consume electricity for refrigeration compressors, HVAC, lighting, and equipment. Energy intensity varies by climate zone, store format, and building age. Larger stores may have lower intensity per square meter due to economies of scale. Track utility consumption normalized by retail floor area. Benchmark across store portfolio identifying high consumers for retrofit priority. LED lighting retrofits, HVAC controls, and refrigeration optimization reduce consumption.

kWh per sqm per year

Upstream Product Carbon Footprints

Sold products represent dominant lifecycle emission source for retailers. Product footprints vary enormously by category: Fresh produce, dairy, and grains have lower intensity. Beef and lamb have high intensity from enteric methane. Packaged processed foods include manufacturing and packaging emissions. Collect product carbon footprints from suppliers through engagement programs or use lifecycle databases. Calculate total Scope 3 Category 11 from sales volumes and category-level emission intensities.

Product emissions per category

Food Waste Disposal Method

Retailers generate food waste from unsold perishables, damaged products, and expiration. Disposal method determines emission impact: Landfill generates methane with high warming potential. Composting avoids methane but has processing emissions. Anaerobic digestion produces biogas for energy and digestate for soil amendment. Food donation to charitable organizations avoids disposal entirely. Track waste volumes by disposal pathway. Optimize inventory management and markdowns reducing waste generation at source.

Food Retailers & Distributors FAQs

Common questions about carbon accounting for this industry

Why are refrigerant emissions so significant for food retailers despite small mass?
Hydrofluorocarbon refrigerants used in commercial refrigeration have very high global warming potential relative to carbon dioxide. Common refrigerants have warming potential thousands of times higher than CO2 over time horizons. Small mass leakage creates large carbon dioxide equivalent emissions. Supermarkets operate many refrigeration systems (walk-in coolers, display cases, ice machines) each containing refrigerant charge. Annual leakage rates range from low percentages for well-maintained new systems to higher rates for aging equipment. Cumulative leakage across store portfolio adds substantial emissions. Transition to low-global-warming-potential alternatives including natural refrigerants reduces impact.
Should food retailers report Scope 3 emissions from sold products?
Yes, Scope 3 Category 11 (Use of Sold Products) is material for food retailers representing upstream manufacturing and agricultural emissions embedded in sold products. These emissions typically exceed operational Scope 1 and 2 by large multiples. Retailers influence product footprints through: Procurement policies favoring lower-carbon products. Supplier engagement programs collecting carbon data. Private label product design with sustainability attributes. Sustainable sourcing requirements. Calculate using product-level carbon footprints from suppliers where available or category-level emission intensities from lifecycle databases. Report data coverage and methodology. Focus supplier engagement on highest-emission categories and largest-volume suppliers.
How do food retailers calculate carbon footprints for thousands of products?
Retailers use hybrid approach combining primary data and secondary data: Primary data from suppliers: Engage major suppliers requesting product-specific carbon footprints especially for private label and high-volume products. Category-level emission intensities: Use lifecycle databases providing average emission factors by product category (beef, dairy, packaged foods, etc.) for remaining products. Spend-based estimation: Apply emission factors per dollar of product cost as rough estimate for long-tail products. Report percentage of sales covered by primary supplier data versus estimates. Prioritize data collection for highest-emission categories (meat, dairy) and largest suppliers. Improve data quality over time through expanded supplier engagement.
What strategies reduce food waste emissions in retail operations?
Food waste reduction strategies operate at multiple levels: Prevention: Inventory optimization and demand forecasting reduce over-ordering. Dynamic pricing and markdowns for near-expiration products increase sales. Donation: Partnership with food banks and charitable organizations divert edible food from disposal. Diversion: Composting avoids landfill methane. Anaerobic digestion produces biogas for energy offsetting fossil fuels. Measurement: Track waste by category and cause to identify improvement opportunities. Disposal method hierarchy ranks prevention highest, followed by donation, anaerobic digestion, composting, and lastly landfill. Report food waste intensity per square meter and percentage diverted from landfill.
Can food retailers use renewable energy to reduce operational emissions?
Yes, renewable energy procurement significantly reduces Scope 2 electricity emissions from stores and distribution centers. Strategies include: On-site solar: Rooftop solar on stores and warehouses generates electricity reducing grid consumption. Virtual power purchase agreements: Long-term contracts with renewable projects supporting new capacity development. Renewable energy certificates: Purchase certificates matching portion of electricity consumption to renewable generation. Green tariffs: Select utility programs supplying renewable electricity. Stores have favorable characteristics for solar: Large roof areas, daytime electricity demand matching solar generation. Calculate emission reduction from renewable energy procurement. Report percentage of electricity from renewable sources.
