A sustainable supply chain is one that minimizes environmental harm at every stage, from sourcing and production through to transport and disposal, while still delivering goods reliably and efficiently. In practice, this means replacing high-waste materials and processes with smarter alternatives that reduce carbon emissions, cut down on single-use plastics, and make data more accessible without adding infrastructure. The sections below break down the key questions supply chain professionals are asking in 2026.
What are the biggest sustainability challenges in modern supply chains?
The biggest sustainability challenges in modern supply chains are waste generation, carbon emissions from logistics, and the lack of visibility that makes it hard to measure or improve environmental performance. These challenges are compounded by the fact that supply chains often span multiple countries, transport modes, and partners with very different capabilities and priorities.
Packaging and single-use monitoring devices are a significant source of waste. Electronic data loggers used to track temperature during transport are a clear example: over 80 million single-use plastic devices are discarded every year globally, each containing lithium batteries that require specialist e-waste disposal. This kind of embedded waste is easy to overlook because it sits inside the logistics process rather than on a shelf in a store.
Emissions from road, sea, air, and rail transport add another layer of complexity. Reducing these requires coordination across carriers, suppliers, and buyers, which is difficult when data is fragmented or only available after a shipment has been completed. Without accurate, accessible data, it is hard to identify where the biggest gains can be made.
How do companies measure their supply chain’s environmental impact?
Companies measure their supply chain’s environmental impact primarily through carbon accounting frameworks that categorize emissions into three scopes. Scope 1 covers direct emissions, Scope 2 covers purchased energy, and Scope 3 covers all indirect emissions across the value chain, including transport, waste, and the goods and services a company buys. For most businesses, Scope 3 is by far the largest and hardest to measure.
Practical measurement approaches include lifecycle assessments, supplier audits, and tracking the environmental footprint of specific materials or processes. The challenge is that many companies rely on estimates rather than actual data, particularly for logistics-related emissions. This is partly because the tools used in logistics, such as traditional electronic data loggers, are not designed to feed into sustainability reporting. They capture temperature data but generate physical waste that rarely gets accounted for in environmental calculations.
Green supply chain practices are increasingly shifting toward solutions that generate less waste by design, rather than relying on offsetting or end-of-life recycling programs that are difficult to verify. Measuring what goes in, not just what comes out, is becoming the standard expectation for credible sustainability reporting.
What does sustainable cold chain monitoring look like in practice?
Sustainable cold chain monitoring means tracking temperature and humidity throughout a shipment without generating the electronic waste that traditional monitoring devices create. In practice, it involves choosing monitoring technology that is designed to be low-impact from the start, not just recyclable in theory.
Electronic data loggers, whether single-use or reusable, are built from plastic, electronics, and lithium batteries. Single-use versions are discarded after one trip and require e-waste disposal. Reusable versions last longer but eventually become e-waste as well. Both types typically require USB or Bluetooth connections to retrieve data, which adds friction and limits who can access information quickly.
Paper-based data loggers take a different approach. Because they use a lithium-free battery design, they avoid one of the most environmentally costly components in traditional loggers. Lithium extraction and disposal carry significant environmental burdens, and eliminating lithium from the equation is a meaningful step, not just a marginal improvement. Paper-based loggers can also be recycled through standard paper waste streams globally, which means disposal does not require specialist handling or separate collection systems. This makes cold chain sustainability practical for both senders and receivers, regardless of where a shipment ends up.
Which industries are leading the shift to sustainable supply chains?
The industries leading the shift to sustainable supply chains are those under the most direct pressure from customers, partners, and their own operational experience to reduce waste and improve transparency. Food and beverage, pharmaceuticals, and floriculture are among the most active sectors making this transition in 2026.
In food and beverage, the combination of perishable goods and high shipment volumes creates both urgency and opportunity. Fresh produce, fish, meat, and dairy all require precise temperature monitoring, and the sheer number of shipments means that switching to lower-waste monitoring tools has a significant cumulative impact.
The pharmaceutical and life sciences sector is moving quickly for a different reason. Many pharmaceutical companies operate strict IT security policies that prevent USB devices from being connected to networked computers, making traditional electronic data loggers genuinely problematic to use. This creates a practical incentive to adopt alternatives that do not rely on USB data retrieval.
Floriculture, particularly in the Netherlands and other major flower-exporting regions, is also a strong adopter. The sector handles enormous volumes of temperature-sensitive shipments, and the environmental cost of single-use plastic monitoring devices has become a visible issue for exporters who are already focused on sustainable growing practices.
How Tapp supports sustainable cold chain monitoring
Tapp has developed the world’s first paper-based data logger, designed specifically to make cold chain monitoring both more sustainable and simpler to use. Where traditional electronic data loggers create e-waste and require specialist disposal, Tapp’s paper-based loggers are recyclable through standard paper waste streams globally and use a lithium-free battery, removing two of the most environmentally harmful elements from the monitoring process.
In practice, this means:
- No e-waste: Paper-based loggers are recycled alongside ordinary paper, with no specialist collection or disposal required.
- Lithium-free design: Eliminating lithium batteries reduces environmental impact at both production and end-of-life stages.
- NFC smartphone tap: Any NFC-enabled smartphone can read the logger instantly, with no app, no USB connection, and no dedicated hardware needed.
- Automatic cloud upload: Data syncs to the TappOS dashboard the moment the label is tapped, giving both sender and receiver immediate access.
- Universal transport compatibility: Suitable for road, sea, air, and rail, with a waterproof coating and flight-safe battery.

Frequently Asked Questions
Can paper-based data loggers match the accuracy and reliability of electronic data loggers?
Yes. Paper-based data loggers are engineered to meet the same temperature monitoring accuracy standards as traditional electronic loggers, making them suitable for regulated industries like pharmaceuticals and food. The key difference is in the hardware design and end-of-life impact, not in monitoring performance. For shipments where compliance documentation is required, the data captured and uploaded via NFC is just as audit-ready as data retrieved from a USB device.
How do I get started with switching from electronic to paper-based cold chain monitoring?
The easiest starting point is to audit one product line or trade lane where single-use electronic loggers are currently used and calculate how many devices are discarded per month. This gives you a concrete baseline for both waste reduction and cost comparison. From there, running a parallel trial with paper-based loggers on the same shipments lets you validate performance before committing to a full switch. The Tapp team can support this process with onboarding guidance and access to the TappOS dashboard.
What happens to the data if a recipient doesn't tap the logger at the destination?
The logger continues recording temperature data throughout the journey regardless of when it is tapped, so no data is lost if the tap happens later than expected. The full temperature history is stored on the logger and uploaded to the TappOS cloud dashboard the moment any NFC-enabled smartphone reads it, whether that’s at the destination, during a customs check, or at a later inspection point. Senders can also tap the logger at dispatch to initiate monitoring and get an early data sync.
How should we handle Scope 3 emissions reporting when our logistics partners don't share data?
This is one of the most common friction points in supply chain sustainability reporting. A practical first step is to request emissions factors or carrier-level data directly from your logistics providers, as many now publish this under pressure from enterprise customers and ESG reporting requirements. Where actual data is unavailable, recognised estimation methodologies such as the GLEC Framework provide a defensible basis for Scope 3 calculations. Switching to monitoring tools that generate less embedded waste, like lithium-free paper-based loggers, also reduces the portion of Scope 3 emissions tied to logistics consumables, which is a measurable and verifiable improvement.
Are there regulatory or certification requirements that paper-based loggers need to meet for pharmaceutical shipments?
Pharmaceutical cold chain monitoring is governed by guidelines such as GDP (Good Distribution Practice) in the EU and equivalent standards in other markets, which specify that temperature data must be accurate, tamper-evident, and retrievable for audit purposes. Paper-based loggers designed for this sector need to meet those data integrity and traceability requirements, not a specific hardware format. It is worth confirming with your quality or compliance team that the logger’s specifications, including measurement intervals, alarm thresholds, and data export formats, align with your standard operating procedures before deployment.
What are the most common mistakes companies make when trying to green their supply chains?
One of the most frequent mistakes is focusing on visible, consumer-facing packaging while overlooking embedded waste inside the logistics process itself, such as single-use monitoring devices, desiccants, and protective materials that never reach the end customer. Another common pitfall is relying on offsetting or recycling programs that are difficult to verify or that require infrastructure not available at the destination. The most effective approach is to reduce waste by design at the point of specification, choosing materials and tools that are inherently lower-impact rather than managing their disposal after the fact.
Can a single cold chain monitoring solution work across road, sea, air, and rail shipments?
It can, but it requires a logger that meets the regulatory requirements for each transport mode, particularly aviation, which restricts lithium battery capacity and mandates compliance with IATA dangerous goods regulations. This is one reason lithium-free battery designs have a practical advantage beyond sustainability: they simplify compliance across multimodal shipments. A waterproof or moisture-resistant coating is also important for sea freight and refrigerated road transport where condensation is a factor. Verifying that a logger is certified for all relevant transport modes before standardising on it across your network saves significant operational friction later.
