Cold chain logistics has a significant environmental impact, driven primarily by high energy consumption from refrigeration systems, carbon emissions from temperature-controlled transport, and the disposal of millions of single-use plastic monitoring devices every year. The combined effect of fossil-fuel-powered vehicles, energy-intensive cold storage, and non-recyclable packaging materials makes cold chain one of the more resource-heavy segments of global logistics. The sections below unpack the key environmental questions that supply chain professionals are asking in 2026.
How much CO2 does cold chain logistics produce?
Cold chain logistics is a major contributor to global carbon emissions because it depends on continuous refrigeration, diesel-powered transport, and energy-intensive cold storage facilities. Refrigerated vehicles consume significantly more fuel than standard trucks due to the additional power required to maintain low temperatures throughout a journey. When you multiply this across millions of shipments by road, sea, air, and rail, the cold chain carbon footprint adds up quickly.
Air freight is the most carbon-intensive transport mode and is frequently used for high-value perishables such as pharmaceuticals, fresh produce, and flowers. Sea freight produces far lower emissions per unit of cargo but still relies heavily on heavy fuel oil. Road transport sits between the two and accounts for the majority of last-mile cold chain deliveries globally. Across all modes, the energy needed to sustain temperature control throughout a journey is consistently higher than for ambient cargo.
What types of waste does cold chain logistics generate?
Cold chain logistics generates three main categories of waste: packaging waste, food and product spoilage, and electronic waste from monitoring devices. Each of these waste streams carries a distinct environmental cost, and all three are growing as global cold chain volumes increase.
Packaging waste includes single-use insulated boxes, gel packs, dry ice, and polystyrene liners that are difficult or impossible to recycle through standard waste streams. Food spoilage, caused by temperature excursions during transit, results in discarded product that carries an embedded carbon cost from everything that went into producing and transporting it.
Electronic waste from monitoring devices is a less visible but serious problem. Electronic data loggers, both single-use and reusable, contain plastic housings, circuit boards, and lithium batteries that require specialist e-waste disposal. Industry estimates suggest more than 80 million single-use electronic loggers are discarded globally every year, the vast majority ending up incinerated or in landfill. Reusable electronic loggers reduce this figure somewhat but still generate e-waste at end of life.
What are the biggest sustainability challenges in cold chain monitoring?
The biggest sustainability challenges in cold chain monitoring are the widespread use of single-use plastic electronic loggers, the difficulty of disposing of lithium batteries safely, and the lack of a scalable, low-waste alternative that still meets professional accuracy standards.
Single-use electronic loggers are the industry default. They are made from plastic and electronics and contain lithium batteries, all of which require careful e-waste handling. In practice, many end up in general waste because proper e-waste infrastructure is inconsistent across countries and logistics chains. The scale of the problem is significant: with tens of millions of units discarded annually, the cumulative waste from cold chain monitoring alone is substantial.
Reusable electronic loggers reduce the number of units in circulation but introduce their own challenges. They require collection, cleaning, battery replacement, and redistribution, which adds logistical complexity and still results in e-waste at end of life. Neither option offers a clean exit from the plastic and battery waste cycle.
A further challenge is the battery itself. Most electronic loggers use lithium batteries, which are energy-intensive to manufacture, difficult to recycle, and classified as hazardous waste in many jurisdictions. Paper-based loggers offer a meaningful advantage here: their batteries are lithium-free, designed to power a single-use NFC circuit rather than a full electronic device, which means the chemical footprint is dramatically smaller and the end-of-life disposal is far simpler.
How can companies reduce the environmental impact of cold chain logistics?
Companies can reduce the environmental impact of cold chain logistics by optimising transport routes, improving packaging efficiency, reducing product spoilage through better monitoring, and switching to lower-waste monitoring technologies. No single change eliminates the cold chain carbon footprint, but a combination of operational and material improvements can make a measurable difference.
- Route and load optimisation: Consolidating shipments and planning efficient routes reduces fuel consumption and the number of refrigerated vehicles on the road.
- Improved insulation and packaging: Using reusable thermal packaging or right-sized insulated containers reduces single-use packaging waste per shipment.
- Reducing spoilage: Better temperature visibility during transit helps identify problems before products are lost, reducing the embedded carbon cost of spoiled goods.
- Switching from single-use electronic loggers to paper-based alternatives: Electronic data loggers require e-waste disposal, while paper-based loggers can be recycled through standard paper waste streams, eliminating lithium battery waste and plastic housing from the disposal equation.
- Choosing lower-emission transport modes: Where lead times allow, shifting from air to sea or rail freight significantly reduces the cold chain CO2 emissions per shipment.
The monitoring device choice is often overlooked in sustainability planning, but at the volumes involved across global cold chains, switching away from single-use electronic loggers can remove a significant source of e-waste from a company’s Scope 3 footprint.

Frequently Asked Questions
Are paper-based data loggers as accurate and reliable as electronic loggers for temperature monitoring?
Yes. Paper-based loggers like Tapp’s are engineered to meet the same professional accuracy standards as conventional electronic loggers, recording temperature data throughout a shipment’s journey without compromise. The key difference is in the materials and disposal method, not the quality of the data captured. For regulated industries such as pharmaceuticals, it is worth confirming that any logger — paper-based or electronic — meets the specific compliance requirements applicable to your shipment type, such as GDP or FDA guidelines.
What is Scope 3 emissions, and why does cold chain monitoring contribute to it?
Scope 3 emissions cover all indirect greenhouse gas emissions that occur in a company’s value chain but are not directly owned or controlled by that company — including upstream and downstream logistics, packaging, and waste disposal. Cold chain monitoring devices fall into this category because their manufacturing, use, and disposal all generate emissions and waste that contribute to a company’s overall environmental footprint, even if the devices are supplied by a third party. Switching from single-use electronic loggers to recyclable paper-based alternatives is a practical way to reduce Scope 3 e-waste without disrupting core logistics operations.
How do I get started with transitioning from electronic loggers to paper-based alternatives in my supply chain?
The simplest starting point is to audit your current logger usage — how many units you deploy per month, which shipment lanes they cover, and how they are currently disposed of. From there, you can run a pilot on a specific lane or product category using Tapp’s paper-based loggers to compare performance, cost, and disposal outcomes before committing to a broader rollout. Tapp’s team can support this process and help you map the e-waste reduction impact against your existing sustainability reporting.
What happens to a Tapp paper-based logger if a recipient doesn't know how to recycle it correctly?
Because Tapp’s loggers are designed to be recycled through standard paper waste streams, recipients do not need specialist knowledge or access to e-waste facilities — they can simply dispose of the label in ordinary paper recycling, the same way they would discard cardboard or paper packaging. This is a significant practical advantage over electronic loggers, which require correct e-waste disposal that is often unavailable or ignored at the destination end of a shipment. Clear disposal instructions can also be printed directly on the label to make the process even more straightforward.
Can paper-based loggers handle the full range of cold chain temperature requirements, including frozen shipments?
This is an important consideration when evaluating any monitoring technology for cold chain use. It is recommended to verify the specific temperature range and environmental specifications of the logger you are considering against the requirements of your shipment — whether that is chilled (2–8°C), frozen (-20°C), or ultra-cold. Contact Tapp directly to confirm which temperature profiles their current paper-based logger range supports and whether it is suitable for your specific cold chain application.
Is there a cost difference between paper-based loggers and conventional single-use electronic loggers?
Paper-based loggers are generally cost-competitive with single-use electronic loggers, and when you factor in the avoided cost of e-waste disposal — which in some jurisdictions requires paid specialist collection — the total cost of ownership can be lower. Beyond direct cost, companies operating under ESG reporting frameworks or facing regulatory pressure on waste reduction may find that the sustainability case adds further value that offsets any unit-price differences. Requesting a quote from Tapp and comparing it against your current logger spend, including disposal costs, is the most accurate way to assess the financial impact for your operation.
How does reducing cold chain monitoring waste contribute to broader corporate sustainability goals?
Cold chain monitoring waste — particularly the tens of millions of single-use electronic loggers discarded annually — sits within a company’s Scope 3 footprint and increasingly appears in ESG audits, supplier assessments, and sustainability reports. Switching to recyclable, lithium-free monitoring devices is a measurable, documentable change that directly reduces e-waste generation and can be quantified in annual sustainability disclosures. It also signals to customers, partners, and regulators that sustainability is being addressed at an operational level, not just at a high-level policy level.
