Refrigerated transportation connects farms, processors, wholesalers, retailers and consumers, but its statistics span different definitions. The figures below distinguish vehicle estimates, shipment models, food-loss measures, equipment specifications, emissions factors and survey results by geography and period.
Key Refrigerated Transportation Statistics
The most broadly useful figures include:
- 416,716 refrigerated trucks were estimated to be involved in U.S. food transportation in the FDA analysis published in 2013.
- 68,916 firms were estimated to operate the U.S. refrigerated-food truck fleet in the FDA’s analysis based on available DOT and Census data, published in 2013.
- 383,424 covered refrigerated trucks were included in the FDA’s proposed-rule estimate after excluding carriers below $500,000 in annual revenue in the United States.
- 52.1 million annual truck-related food shipments were estimated to be affected by the proposed rule in the United States using the 2007 Commodity Flow Survey.

U.S. Refrigerated Transportation Fleet and Shipment Statistics
The FDA’s Preliminary Regulatory Impact Analysis for the proposed rule on Sanitary Transportation of Human and Animal Food provides an older U.S. scale estimate. It analyzed available DOT and Census data and annualized shipment information from the 2007 Commodity Flow Survey, so these figures are estimates rather than a current vehicle registry.
| U.S. measure | Estimate | Definition and period |
|---|---|---|
| Refrigerated trucks | 416,716 | Food transportation; analysis published 2013 |
| Operating firms | 68,916 | Estimated firms operating the fleet; analysis published 2013 |
| Covered trucks | 383,424 | After excluding carriers below $500,000 annual revenue |
| Covered firms | 23,507 | Firms under the proposed-rule coverage estimate |
| Affected truck-related shipments | 52.1 million annually | Annualized from the 2007 Commodity Flow Survey |
| Covered truck-only shipments | 51.5 million annually | Proposed-rule estimate |
The FDA estimated that the proposed rule affected about 25% of truck-and-rail shipments. Its representative-load calculation used four-digit Standard Classification of Transported Goods commodity tonnage, which describes the analytical basis rather than adding another fleet or shipment count.
The source cautions that self-reporting and exclusion of intrastate-only trucks may understate the total fleet and firm counts. Shipment totals also assume one vehicle movement per product and may omit transfers or count co-loaded products separately; the truck-only estimate excludes specified shelf-stable packaged commodities and approximates 90% of milk and cream shipments as excluded.
Global Refrigerated Transportation Data and Food-Loss Trends
A 2013 Transport Refrigeration Project sector presentation estimated about 4.0 million refrigerated vehicles worldwide across small vans, large trucks and trailers. The class breakdown shows the scale of the equipment population, while the food-loss figures from FAO cover broader post-harvest stages and should not be read as transport-only rates.
| Worldwide refrigerated road class | Estimated units, 2013 | Typical cooling capacity at 0°C | Typical refrigerant charge |
|---|---|---|---|
| Small trucks and vans | 1.6 million | 4 kW | 2.5 kg |
| Large refrigerated trucks | 1.2 million | 7 kW | 5.5 kg |
| Trailers and semi-trailers | 1.2 million | 17 kW | 7.5 kg |
Source: UNEP, Transport Refrigeration Project: Sector study on refrigerated transport in South Africa. These are presentation estimates and typical class specifications, not current registry counts or measured fleet averages.
FAO’s global food-loss indicator measures losses from on-farm activities through transport, storage, wholesale and processing. It does not isolate refrigerated transportation.
| Geography or commodity group | 2015 | 2023 |
|---|---|---|
| Global food loss | 13.0% | 13.3% |
| Northern America and Europe | 9.4% | 10.0% |
| Sub-Saharan Africa | 22.1% | 23.0% |
| Fruits and vegetables | 23.2% | 25.4% |
| Meat and animal products | 13.9% | 14.0% |
Source: FAO, 12.3.1 Global food losses.
In 2023, least-developed countries recorded an estimated 19.9% food loss, while small island developing states recorded 19.0%. Roots, tubers and oil-bearing crops recorded 12.3% loss, and cereals and pulses recorded 8.4%; all are FAO estimates across the covered supply-chain stages.
The South Africa presentation estimated 5,500–6,500 small refrigerated trucks and vans, 4,000–4,500 large refrigerated trucks, and 3,000–3,500 refrigerated trailers and semi-trailers in that country in 2013. Those ranges are approximate stock estimates from the presentation, not a registry census.
Cold-Chain Emissions and Refrigerant Statistics
Cold-chain environmental measures combine several distinct systems. The UNEP-FAO report estimated that food cold chains accounted for 4% of global greenhouse-gas emissions when refrigeration technology and food loss caused by inadequate refrigeration were included, so the figure is broader than transport equipment alone.
The report’s baseline, published in 2022, estimated that 14% of food produced for human consumption was lost and 17% was wasted. It linked inadequate refrigeration across the food cold chain to the loss of 12% of total food production in 2017; that attribution was not limited to transport.
The same report placed 811 million people in a global hunger context and stated that 3 billion people could not afford a healthy diet. These are food-system context measures, not refrigerated-transport outcomes.
For refrigerant-related comparisons, a 2020 application breakdown in EPA’s Global Mitigation of Non-CO2 Greenhouse Gases report estimated the following shares of global GWP-weighted HFC emissions:
- Refrigerated transport represented 8%.
- Retail food refrigeration represented 31%.
- Motor-vehicle air conditioning represented 16%.
- Cold storage and industrial process refrigeration together represented 6%.
These are application-share estimates. Retail, vehicle air conditioning, and industrial refrigeration are contextual comparators rather than refrigerated-freight measurements.
EPA’s Refrigerated Trailers and Transport Refrigeration Units page documents the 2023 TRU calculator and its use of MOVES3 outputs for estimating diesel TRU emissions. It identifies a model basis, not a national TRU count or measured national emissions total; results depend on user inputs and scenario assumptions.
Operational Pressures in Refrigerated Transportation
Refrigerated transport must maintain temperature while moving variable products through a chain with transfers, mixed loads and different vehicle classes. The available statistics show why fleet size, shipment definitions, equipment capacity and refrigerant management should be treated as separate measures.
The FDA’s older proposed-rule estimate counted 416,716 refrigerated trucks and 68,916 operating firms, while the revenue-threshold coverage estimate counted 383,424 trucks and 23,507 firms. The covered figures are regulatory-coverage estimates, not a census of every refrigerated vehicle or carrier.
The equipment presentation’s typical capacities increased from 4 kW for small trucks and vans to 7 kW for large trucks and 17 kW for trailers at 0°C. Typical refrigerant charges likewise ranged from 2.5 kg for small vehicles to 5.5 kg for large trucks and 7.5 kg for trailers, but these are class specifications rather than fleet-average measurements.
EPA’s WARM v15 documentation provides model factors for fresh fruits and vegetables rather than universal route averages:
| Fresh fruits and vegetables transport factor | Estimate | Scope |
|---|---|---|
| Transportation energy | 2.12 million Btu per short ton | WARM v15 factor |
| Transportation-energy emissions | 0.15 metric tons CO2e per short ton | WARM v15 factor |
| Refrigerant-related non-energy emissions | 0.01 metric tons CO2e per short ton | Non-energy factor |
Source: EPA, Documentation for Greenhouse Gas Emissions and Energy Factors Used in the Waste Reduction Model (WARM), Version 15. Route, mode and load assumptions apply, and the refrigerant factor is not a direct leak measurement.
Food-Safety and Cold-Chain Coordination Statistics
Cold-chain performance matters beyond vehicle availability because food loss can occur at several stages. The UNEP-FAO figures place refrigeration within a wider food-security and emissions system, while U.S. retail and consumer estimates show the scale of food that can remain uneaten without identifying transportation as the sole cause.
USDA ERS estimated that 133 billion pounds of food went uneaten at U.S. retail and consumer levels in 2010. That represented 31% of the 430 billion pounds of available food supply, with an estimated retail value of $162 billion.
Source: USDA ERS, Food Availability (Per Capita) Data System: Food Loss. These historical estimates cover multiple causes and are not limited to temperature-sensitive food or refrigerated transportation.
Coordination also includes the scale and perspective of cold-chain organizations. In the Global Cold Chain Alliance Industry Trends Report, 48% of survey respondents worked in companies with more than 10 million cubic feet.
That 48% is a 2019 survey result from 182 respondents connected to GCCA stakeholders, not an estimate for the entire refrigerated-transport industry. The survey measures respondent-company profiles and perceptions or expectations rather than realized market outcomes.
Taken together, the available statistics describe a system with estimated U.S. fleet and shipment scale, a global vehicle population estimated in 2013, measurable food losses across broader post-harvest stages, and model-based emissions factors. The definitions and limitations matter: none of the broad food-loss percentages should be converted into a refrigerated-transport-only loss rate.
