Why Supply Chain Transparency Matters to Sustainable Food Logistics

A food company can have detailed information about its direct suppliers while still having limited visibility into the wider supply chain. That gap can make it harder to understand where environmental impacts occur, which parts of the supply network require greater attention and where sustainability improvements could have the greatest effect.

For food companies, the challenge extends well beyond the manufacturing facility. Food and ingredients can move through farms, processors, packaging suppliers, transportation providers, warehouses, distributors and retailers before reaching the customer. Each stage can involve different resource requirements and environmental impacts, making supply chain transparency an important part of understanding sustainability across the food logistics network.

The U.S. Department of Agriculture's Economic Research Service provides a useful illustration of this complexity. Its Resource Requirements of Food Demand data measures energy, employment and water use across 16 stages of the U.S. food system, including food processing, transportation and storage, wholesale, retail and food services. The data shows that resource use varies across supply chain stages, rather than being concentrated in a single part of the food system.

Why sustainability starts with supply chain visibility

Sustainability decisions depend on understanding where resources are being used and where environmental impacts occur. Without sufficient visibility, companies may have difficulty determining which suppliers, materials or logistics activities deserve closer attention.

This does not mean every company needs complete information about every activity in its entire supply network. Instead, transparency should provide enough useful information to understand the areas that are most relevant to the products and supply chains being managed.

The USDA's analysis of food system resource use reinforces why this broader view matters. Its analysis shows that water, energy and employment are distributed differently across food supply chain stages. More than one-quarter of U.S. freshwater use is linked to the food system, while the majority of food-system water use occurs on farms and additional water use occurs downstream. Energy use also extends beyond production, including activities such as refrigeration and retail electricity use.

For food logistics leaders, this means sustainability cannot be evaluated only by looking at what happens inside a processing facility. Transportation, storage, refrigeration, packaging and distribution can also form part of the environmental picture.

Knowing your supplier doesn't mean knowing your supply chain

A direct supplier relationship provides visibility into one layer of a supply network, but it does not necessarily reveal what happens further upstream.

A food manufacturer may know where it purchases an ingredient or packaging material without knowing where the supplier obtains its own inputs, how those materials are produced or which processes require significant amounts of energy, water or other resources.

This distinction becomes particularly important when companies rely on supplier information to understand sustainability performance. A supplier may provide information about its own facility while depending on other organizations for agricultural inputs, raw materials, packaging components or processing activities.

Supply chain transparency therefore requires more than knowing who a company buys from. It requires understanding which upstream relationships and activities are relevant to the products being sourced and moved.

The objective is not to create an unlimited map of every company connected to a product. It is to identify the parts of the supply network where additional information could materially improve sustainability decisions.

Visibility needs to extend across the logistics network

Sustainability information is often associated with procurement, but logistics creates additional areas where visibility matters.

The movement and storage of food can involve transportation, refrigerated warehouses, distribution centers, packaging operations and other activities between production and the final customer. The USDA's Resource Requirements of Food Demand data specifically separates transportation and storage, food wholesale, food retail and other stages, providing a way to examine resource use across different parts of the food system.

This broader view can change the questions companies ask. Instead of focusing only on whether a supplier has an environmental policy, companies may also need to understand where materials originate, how they are transported, whether temperature-controlled storage is required, how products are packaged and how materials move through distribution.

The level of information required will vary by product and supply chain. A refrigerated food product, for example, can involve different logistics considerations from a shelf-stable product. The important point is that sustainability information becomes more useful when it reflects the actual path a product takes through the supply chain.

Packaging shows the value of product-level data

Packaging is another example of why supply chain transparency needs to connect information to specific products and materials.

A food manufacturer may know how much it spends on packaging, but cost information alone does not provide a complete picture of the materials being used, their quantities, their composition or what happens to them after use.

Packaging information can also be relevant to logistics decisions. Material type and packaging design can affect product protection, shipment configuration, storage requirements and material use. Having reliable information at the product and packaging level can therefore help companies evaluate sustainability alongside practical supply chain requirements.

GS1 US published guidance on extended producer responsibility packaging requirements in June 2026 to help companies prepare packaging data for reporting requirements. The guidance highlights the need for reliable packaging data and discusses capturing information such as material, weight and sustainability attributes consistently across products and packaging levels.

The example demonstrates a broader principle: sustainability information becomes more useful when it can be connected to the specific products, materials and supply chain activities to which it relates.

More data does not always mean better transparency

A larger supplier database does not automatically create better supply chain transparency. Information can be incomplete, inconsistent, outdated or difficult to compare across suppliers.

The more useful question is therefore not how much information a company can collect, but whether the information is reliable enough and relevant enough to support a decision.

The National Institute of Standards and Technology's Supply Chain Traceability Principles: A Manufacturing Meta-Framework addresses a related challenge. Published in September, the framework focuses on organizing, linking and querying supply chain information across different systems and organizations. It also emphasizes verifiable traceability data and selective disclosure, allowing organizations to share necessary information while protecting sensitive intellectual property.

Although the framework is not specific to food sustainability, its approach is relevant to transparency because supply chain information becomes more useful when organizations can connect information from different parts of a network and establish greater confidence in what that information represents.

For food companies, that could mean distinguishing between supplier-provided information, internally measured information and estimates, while also keeping track of when information was collected and what product or activity it describes.

What should companies actually do with all this information?

Transparency becomes valuable when it changes what a company does with the information it collects and companies may use supply chain information to identify materials that require further review, compare suppliers, examine resource-intensive activities, evaluate packaging choices or determine where transportation and storage practices should be assessed more closely.

This does not require every supplier to provide the same amount of information. In fact, a more targeted approach may be more practical.

The U.S. Environmental Protection Agency's Supply Chain Guidance recommends strategically choosing suppliers for engagement. The guidance notes that organizations may consider factors including supplier importance, environmental challenges and the potential business relevance of supplier environmental performance. For food manufacturers with large supplier networks, this approach can help direct attention toward suppliers and materials where better information is most likely to support meaningful decisions.

The result is a shift from collecting information for its own sake toward using supply chain visibility as an input into sourcing, packaging and logistics decisions.

Supplier engagement makes transparency actionable

Information alone does not improve environmental performance. Companies also need a way to work with suppliers when the information identifies an opportunity for improvement.

The EPA's Green Suppliers Network provides one example of this approach. The program helps manufacturers and supply chains identify opportunities related to resource efficiency, waste reduction and environmental performance, while encouraging companies to engage suppliers and recognize improvements.

The broader lesson is that transparency should create a two-way relationship between buyers and suppliers. Companies can communicate what information is important, suppliers can provide information about their practices and both sides can identify areas where additional action may be appropriate.

This can also reduce the tendency to treat sustainability questionnaires as an end in themselves. A supplier request is more useful when the information collected has a clear purpose and can lead to a discussion, evaluation or improvement effort.

Sustainable logistics starts with knowing what is happening

Supply chain transparency is not simply about creating a larger supplier database or collecting more sustainability documents. It is about developing enough reliable visibility to understand what is happening across the supply network and use that information to make better decisions.

For food companies, that visibility can extend from agricultural and processing activities through packaging, transportation, storage, wholesale and distribution. USDA data demonstrates how resource use varies across these stages, while EPA guidance illustrates the value of targeted supplier engagement. NIST's work also highlights the importance of connecting and verifying supply chain information across complex networks.

A sustainable food logistics strategy therefore starts with a simple question: What does the company actually know about the supply chain supporting its products?

The answer can reveal where information is strong, where visibility is limited and where better data could support more informed sourcing and logistics decisions. In a supply chain that extends far beyond a company's own facilities, that visibility can be the starting point for more effective sustainability management.
