Retail supply chains are under increasing pressure to improve efficiency, reduce costs, and meet sustainability targets. From global sourcing to last-mile fulfilment, every carton shipped carries an environmental footprint, and understanding that impact is the first step toward a more responsible supply chain.

At Unsworth, we help retailers measure and manage carbon emissions across their carton shipments. Our Carton Calculator provides the insights needed to make smarter, data-driven logistics decisions.

Why Carbon Tracking Matters for Retailers

The environmental impact of retail logistics goes far beyond the products themselves. Freight movements, warehousing operations, packaging choices, and last-mile delivery all contribute to a retailer’s total carbon footprint.

As customer expectations and regulatory requirements increase, retailers are under pressure to report on emissions with greater accuracy. However, many lack the tools to calculate this effectively across their supply chain.

This is where Unsworth’s Carton Calculator comes in.

By combining logistics data with emissions modelling, we enable retailers to understand the true carbon cost of moving goods through their network, from supplier to distribution centre, and on to store or customer.

How the Carton Calculator Works

Accurate Carton-Level Emissions Data

Our Carton Calculator enables retailers to quantify the carbon footprint of individual shipments at carton level. It factors in key variables including:

• Transport mode (air, sea, road)
• Distance travelled
• Carton weight and dimensions
• Warehousing and handling touchpoints

This provides clear, actionable data that helps retailers benchmark performance across suppliers, product categories, and regions.

Smarter Fulfilment and Distribution

Retail supply chains are often complex, with goods moving through multiple warehouses, consolidation points, and fulfilment centres.

By analysing shipment-level emissions, retailers can identify inefficiencies such as:

• Unnecessary multi-leg transport
• Underutilised containers
• Inefficient distribution routing

This insight supports more streamlined fulfilment strategies, reducing both cost and carbon output.

Optimised Freight Planning

Our logistics expertise allows retailers to make better decisions across their freight network. Whether shipping full container loads or consolidated carton shipments, we help identify the most efficient routing options.

This includes:

• Smarter consolidation of smaller shipments
• Reduced reliance on air freight where viable alternatives exist
• Improved container utilisation rates

The result is a more cost-effective and lower-impact supply chain.

Global Supply Chain Visibility

For retailers sourcing globally, transparency is essential. Our Carton Calculator supports end-to-end visibility across international supply chains, helping businesses understand the environmental impact of goods moving from manufacturing hubs to regional distribution networks.

This allows retail teams to compare sourcing and logistics strategies on both cost and carbon performance.

Towards a More Sustainable Retail Supply Chain

Sustainability is no longer optional in retail — it is a core business requirement. From investor expectations to consumer behaviour, retailers are expected to demonstrate measurable progress in reducing supply chain emissions.

By using the Carton Calculator, retailers can:

• Track emissions at shipment and SKU level
• Identify opportunities to reduce carbon output
• Improve logistics efficiency and cost control
• Support ESG reporting with reliable data

At Unsworth, we provide the tools and expertise to help retailers build smarter, more sustainable supply chains.
