Cold Chain Statistics: Temperature Excursions, Spoilage and Cost

How Big Is Cold Chain Logistics?

Cold chain logistics is one of the fastest-growing corners of the logistics industry, pulled along by biologics, online grocery and the simple fact that more of the world's food is now expected to arrive chilled. The estimates below come from one research house, Global Market Insights (September 2026). Its segment growth rates all run above its 13.8% headline rate, so read the splits as directional.

Food and beverage remains the larger application, projected at $341.5 billion by 2035 at a 15.0% CAGR, against $171.3 billion for pharmaceuticals and healthcare growing at 16.3%. Chilled product (0°C to 8°C) is the largest temperature band at a projected $283.7 billion, while frozen (-18°C to -25°C) grows fastest at 16.1% a year. Asia Pacific is the largest regional market at $152.5 billion in 2026.

Cold Storage Capacity Is Growing Fast

The physical footprint of the largest operators is expanding to match. The Global Cold Chain Alliance (GCCA), the trade body for temperature-controlled warehousing and logistics, publishes an annual list of its largest members.

Capacity represented by GCCA members grew more than 10% into 2025, and in the association's words, "even with the higher costs of capital, the growth in the industry across all regions in 2024 outpaced the prior two years." GCCA adds a caveat worth keeping: the Top 25 additions reflect acquisitions and new facilities, and "this does not suggest the general industry grew at this pace."

The Pharma Slice

Pharmaceutical Commerce's Biopharma Cold Chain Sourcebook, in its ninth edition by 2018, tracked the pharma segment. Its 2016 edition put cold chain at 19% ($12.6 billion) of a $78.8 billion pharma logistics market, rising to 22% ($16.7 billion) by 2020; the 2018 edition counted "more than $15 billion worldwide" inside an $82 billion market and noted that sales of temperature-controlled pharma products were "growing at twice the rate of the pharma industry as a whole." Older numbers, but a long-running series with a consistent method.

What it means: the industry is building cold rooms and buying reefers faster than it is building visibility between them. Capacity is a solved problem you can buy. The handoff between two pieces of capacity is not.

Pharma Cold Chain Losses: Tracing the $35 Billion Figure

If you have read anything about pharma cold chain logistics, you have read that the industry loses $35 billion a year to temperature failures. We use the figure ourselves, so we went looking for where it comes from. A number this large deserves a footnote.

The trail leads to July 2019. Peli BioThermal's 2019 Biopharma Cold Chain Logistics Survey circulated the estimate with attribution to the IQVIA Institute for Human Data Science; Air Cargo News reported it that month as a figure "quoted in the 2019 Biopharma Cold Chain Logistics Survey" that "includes lost product, clinical trial loss and replacement costs, as well as wasted logistics costs and the costs of root-cause analysis." The trade press has repeated it since: the Indianapolis Business Journal in 2023 ("$35 billion annually, according to the IQVIA Institute for Human Data Science"), Manufacturing Chemist in 2024. SupplyChainBrain's 2022 column on "the $35 billion challenge" links the number straight to the Peli survey report.

Three caveats. The underlying IQVIA analysis is not public; every citation we found points to a vendor survey or a trade article. The number is global and covers biopharma broadly, so it should not be applied to any one company's shipments. And as far as we can find it has not been updated since 2019, while biologics spending has grown sharply. Treat $35 billion as an order of magnitude, sourced to IQVIA via Peli BioThermal (2019).

Why the exposure keeps growing: biologics, most of them temperature sensitive, "now comprise 46% of total medicine spending" in the United States as of 2021 after growing 12.5% a year for five years, per the IQVIA Institute, and IATA notes the pharmaceutical industry moves "over one trillion dollars worth of cargo every year." More of a bigger pie needs to stay cold.

How Often Do Excursions Happen?

This is the question with the weakest public data. The best-known survey, Peli BioThermal's 2019 poll of biopharma "key opinion leaders," found 44.6% of respondents reporting "multiple temperature excursions per year" and 16% a monthly occurrence, as Air Cargo News reported it. Statista, which holds the chart behind a paywall, notes the source gives no sample size or method, so treat those shares as one vendor's poll.

What the regulators say is more useful. WHO defines a temperature excursion as "an excursion event in which a TTSPP is exposed to temperatures outside the range(s) prescribed for storage and/or transport," and CDC measures it as how long a unit has been "operating outside the recommended temperature range." CDC's metric counts minutes, not shipments. For the story of what these failures cost, read The $35 Billion Secret Your Pharmacist Doesn't Know About.

Vaccine Wastage: What WHO and UNICEF Report

Vaccines are the cold chain's oldest and most studied cargo, and the loss figures are stark.

The headline number is WHO's, and it is almost always quoted secondhand. The primary text is WHO's 2005 guidance Monitoring vaccine wastage at country level, which opens: "The World Health Organization reports over 50% vaccine wastage around the world," with no derivation. UNEP's 2020 summary softened it to "up to 50% of vaccines are wasted globally every year, a large part because of lack of temperature control and the logistics to support an unbroken cold-chain," and did the pandemic arithmetic: at that rate COVID-19 "could waste potentially a billion vaccines."

A second WHO figure travels the same way. A 2022 study in Tropical Diseases, Travel Medicine and Vaccines cites WHO's 2009 State of the World's Vaccines and Immunization for the statement "that as much as 25% of all vaccine products reach their destination in a degraded state"; in that study 46.2% of the Ethiopian health facilities audited showed poor adherence to WHO storage codes. UNICEF supplies vaccines to 109 countries a year and reaches 45% of the world's children under five. In the United States, CDC sets the storage windows: 2°C to 8°C refrigerated, -50°C to -15°C frozen, -90°C to -60°C ultra-cold.

What it means: WHO's wastage figure counts every cause, including doses discarded from opened multi-dose vials, so it is not a pure cold chain number. WHO attributes wastage in unopened vials "usually" to "cold chain and stock management problems," which makes it a handling and monitoring problem as much as an equipment one.

Food Loss and Waste in the Cold Chain

Food is the larger half of the cold chain and of its losses, and it is measured far better than pharma because the UN agencies have been counting for a decade.

The Global Picture

FAO's Food Loss Index finds "the percentage of food lost globally after harvest on farm, transport, storage, wholesale and processing levels is estimated at 13.3 percent in 2023, up slightly from 13.0 percent in 2015." Waste, the downstream half, is UNEP's Food Waste Index: 1.05 billion tonnes in 2022, "almost one-fifth of all food available to consumers," 132 kilograms per person, split 60% households, 28% food service and 12% retail; food loss and waste together cost the global economy "roughly USD 1 trillion." UNEP's cold chain report sums it up: "an estimated 14 percent of the total food produced for human consumption is lost, while 17 per cent is wasted."

The refrigeration-specific number matters most here. UNEP and FAO's 2022 report found that "lack of effective refrigeration directly results in the loss of 526 million tons of food production, or 12 per cent of the global total," and that developing countries could save 144 million tonnes a year with developed-country cold chains. That lost food produced about 1 gigatonne of CO2 equivalent in 2017, about 2% of global emissions; the food cold chain as a whole accounts for about 4%.

The United States

USDA's Economic Research Service set the U.S. baseline: in 2010, 31 percent of the available food supply at the retail and consumer levels, 133 billion of 430 billion pounds, went uneaten, worth $161.6 billion at retail prices, split 10% at retail and 21% at the consumer level. ReFED's modeling, which covers the full chain from farm to home, counts 70 million tons of surplus food in 2024, about 29% of the U.S. food supply and worth $380 billion, of which 85% ($325 billion) was wasted. That was a 2.2% drop from 2023, the first meaningful decline since the pandemic.

Read the causes with a cold chain eye. Spoilage is 12.9% of surplus, roughly 9 million tons, and buyer rejections, food safety holds, and mistakes and malfunctions add another 6.2%. Those four categories are where temperature history decides the outcome, and together they are about one fifth of everything unsold or uneaten. By food type, produce is 45.4% of surplus, dairy and eggs 12.7%, fresh meat and seafood 5.2%, and frozen food just 1.3%. Frozen food does not forgive a thaw, but it tolerates a dock. Chilled food tolerates neither.

By sector, farms generate 24.2% of surplus, manufacturing 18.8%, food service 17.9%, retail 5.7% and households 33.5%. Surplus food in 2024 produced greenhouse gas emissions equal to 3.5% of the U.S. total, and just under 13% of donatable surplus was donated.

What it means: in food, the cold chain's failure mode is rarely dramatic. It is a pallet of strawberries that arrives two days older than its paperwork says, gets marked down, and ends up in the 12.9%. Nobody files a claim for a markdown.

Where Excursions Happen: Handoffs, Hubs and Docks

Ask anyone who has run a cold chain where it breaks and they will say: at the seams. The reefer is cold. The warehouse is cold. The 45 minutes between them is not. Independent data on what share of excursions occur at handoffs is thin and mostly vendor-published, so there is no statistic card here. What we can show is that the regulators, who read the deviation reports, all point at the same place.

• EU GDP Names the Hub "Where the transportation route includes unloading and reloading or transit storage at a transportation hub, particular attention should be paid to temperature monitoring, cleanliness and the security of any intermediate storage facilities," and temporary storage should be kept as short as possible.
• WHO Names the Apron and the Customs Queue TRS 961 Annex 9 wants shipments moved "as soon as possible after arrival" from "the wharf or airport apron" to temperature-controlled storage, and clearance arranged "to avoid delays during customs clearance that may cause temperature excursions."
• FDA Names the Loading Operation The Sanitary Transportation rule makes the shipper specify an operating temperature in writing, and on request the carrier must "demonstrate that it has maintained temperature conditions during the transportation operation." The dock is where control changes hands.
• CDC Names the Minutes Its excursion metric is "how long a unit has been operating outside the recommended temperature range." A thermometer at the destination says the product is warm. It cannot say when it got that way.

The data we do have agrees: in ReFED's U.S. figures the chilled categories are more than 63% of surplus food while frozen is 1.3%, and chilled product has the least shelf life to spend at each handoff. Your Wine Survived Years in a Barrel shows how a tarmac turns a mild day into a cooked pallet.

Monitoring Adoption and What the Rules Now Expect

Cold chain monitoring used to be a best practice. It is now a documented regulatory expectation in every major market, and the specifications are concrete enough to audit against.

Adoption is harder to measure than requirement, and the public numbers are old or partial. Pharmaceutical Commerce put "specialized tertiary packaging and instrumentation," where data loggers sit, at $4.4 billion of $15 billion in pharma cold chain logistics spending in 2018, up from $3 billion of $12.6 billion in 2016. UNEP and FAO's 144 million tonnes of avoidable loss measures how much of the world still has no cold chain to monitor.

Measured results from monitoring programs are mostly published by the companies selling them, so we left those out. What the primary sources show is the gap the rules are closing, and we have been candid about what passive RFID sees inside it: a dock-door read is a timestamp, not a temperature.

What it means: the standard of evidence has moved to continuous, calibrated and gap-free. The equipment in most networks has not.

What the Numbers Mean for the Pallet Layer

The whole post in four lines. The market is large and growing at double digits. The losses are large, concentrated in chilled product, and poorly measured where they occur. The regulators have converged on continuous, calibrated, gap-free evidence. And the equipment that generates it stops at the edge of the room and the edge of the truck.

The pallet does not stop. It rides under the same product from the outbound dock to the trailer, the cross-dock, the apron and the receiving dock. That is why we built Smart Pallets the way we did: 100% recycled HDPE that needs no ISPM 15 treatment and washes down between loads, with an embedded sensor module carrying cellular GPS, temperature, humidity and shock, built in rather than bolted on, with no scanning, no dock readers and no carrier cooperation.

Pulse, our platform, runs exception-based reporting: quiet when the pallet sits in a qualified cold room, awake the moment it moves or a threshold is crossed, logging a timestamped, geolocated event and routing it to the person who can still act. The silence is data too. Three days with no alerts is three days in spec, the record EU GDP, WHO and CDC describe, and dwell time by facility and lane shows which dock is the 45-minute seam.

• For Pharma Shippers A continuous, gap-free temperature and custody record across handoffs, the evidence GDP asks for at every hub.
• For Food Shippers A time-and-temperature history for the chilled categories that make up most of the surplus, so a markdown becomes a claim with evidence or a lane you fix.
• For Everyone An all-inclusive monthly lease designed to price at or below what you pay for wood pallets today, with pallet, sensors and exception reporting in one flat cost.
