Service Footprint in Logistics: How to Measure Your Shipment Emissions with the GLEC Framework

Service footprint measures the greenhouse gas emissions of every shipment, route or logistics service your company provides or contracts. If you work with large shippers or bid on tenders with sustainability criteria, calculating it is no longer optional — it's the data point they ask for before you sign.

Here's what service footprint is, why the GLEC Framework and ISO 14083 are the reference standard, and what data your company needs to calculate it properly.

What is service footprint in logistics?

Service footprint quantifies the CO₂ equivalent tied to a specific transport or warehousing operation: a truck route, a sea freight shipment, a last-mile delivery, or throughput at a logistics hub. Unlike corporate carbon footprint, which covers a whole organization's activity, service footprint is calculated per route, client or contract, which makes it possible to compare routes and transport modes against each other.

For a shipper, these emissions usually fall under Scope 3. For a carrier with its own fleet, they're Scope 1 and 2. Either way, the challenge is the same: without a common method, the numbers aren't comparable or defensible in front of a client or auditor.

Why are the GLEC Framework and ISO 14083 the reference standard?

The GLEC Framework (Global Logistics Emissions Council), managed by Smart Freight Centre, was the first internationally recognized methodology for accounting logistics emissions. Since 2023 it has been aligned with ISO 14083, which sets the international calculation rules for freight and passenger transport. In practice, applying the GLEC Framework today means calculating in line with ISO 14083.

That alignment carries more weight under CountEmissions EU, the EU regulation that sets ISO 14083 as the reference methodology for reporting transport emissions. In the chemical and distribution sector, SQAS adds another layer: it assesses logistics providers on safety, quality and sustainability through a standardized questionnaire that more and more shippers require from their carriers. You can find the full breakdown in our guide to the GLEC Framework and its relationship with ISO 14083.

What data do you need to calculate your service footprint?

The calculation requires real activity data, not generic estimates:

• Distance and route: origin, destination and the actual path travelled for each shipment.
• Transport mode: road, sea, air, rail or multimodal.
• Vehicle or vessel type: category, size and engine technology.
• Cargo carried: weight or volume, to calculate intensity per tonne-kilometre.
• Fuel or energy consumption: litres, kWh, or invoice data from your transport provider.
• Applicable emission factor: based on fuel type, country and the GLEC/ISO 14083 methodology.

Gathering this data by hand, shipment by shipment, is the most time-consuming part of the whole process — especially when transport is outsourced across several providers.

How Manglai's AI automates the calculation

Manglai's AI removes the manual data collection work from transport emissions:

• Automatic reading of transport invoices: extracts distances, fuel consumption and routes directly from your logistics providers' invoices, in any language or currency.
• Classification by mode and leg: assigns each shipment to its transport mode and applies the matching emission factor without manual work.
• Calculation aligned with GLEC and ISO 14083: applies the standard methodology so your results are comparable and audit-ready.
• Reports ready for clients or tenders: generates reports by route, client or contract, with full traceability back to the source data.

The result: instead of manually rebuilding hundreds of routes, you get an up-to-date, defensible service footprint figure whenever you need it.

If your company moves goods and needs to calculate its service footprint in line with the GLEC Framework, Manglai's service footprint solution automates the entire process, from invoice to report.
