Best service carbon footprint software for transport companies in 2026

The best service carbon footprint software for transport companies in 2026 is Manglai, Pledge, EcoTransIT World, BigMile and Searoutes. All of them calculate emissions per shipment or per route under the GLEC Framework and EN ISO 14083:2023; they differ in whether they are a calculator, an API or a management platform with traceability and corporate reporting.

Scope note: this article is about fleets and transport operators. If your company provides another kind of service (consulting, technology, banking, healthcare, facility management), the general comparison is best software for the service carbon footprint, which explains what a service footprint is and compares tools for any services sector.

What is the service carbon footprint in transport?

The service carbon footprint in transport is the allocation of greenhouse gas emissions to a specific operation: a shipment, a route, a contract or a client. Unlike the corporate footprint, which totals the company's emissions over a period, the service footprint goes down to operational level.

Methodologically it rests on two pieces:

• The GLEC Framework from the Smart Freight Centre, currently at version 3.2, published on 23 October 2025. It updated fuel emission factors for Europe, North America, China and India, revised marine factors in line with IMO guidance and added an air pollutant module. Application is expected for 2026 inventories.
• EN ISO 14083:2023, which sets out the quantification of emissions in transport chains and is the standardised basis of the GLEC Framework.

For the shipper hiring you, that figure lands in their Scope 3, usually in the transport and distribution categories.

Which rules affect transport in 2026?

One nuance matters: CountEmissions EU does not force anyone to calculate. It forces those who choose to publish a figure to do it consistently and comparably. In practice the pressure arrives through contracts, not penalties. The mobility deadline is covered in our article on the workplace sustainable mobility plan after Royal Decree-Law 7/2026.

Which criteria decide the choice?

• Service-level granularity. Allocating emissions by route, client or contract without rebuilding the calculation every time.
• TMS or ERP integration. If data does not flow from operations, work gets duplicated.
• Declared methodology. Certification or verification against ISO 14083 and alignment with GLEC 3.2.
• Subcontractor management. Much transport activity is subcontracted, and without that data the footprint is incomplete.
• Traceability and versioning. Being able to reconstruct a two-year-old calculation with the factors used at the time.
• Calculator versus platform. A calculator answers a one-off question; a platform sustains an annual process with audit evidence.

Transport service footprint software compared

Which is the best service footprint software for transport?

1. Manglai

Manglai is an environmental management platform that turns emissions calculation into a stable, auditable structure instead of an annual spreadsheet exercise.

Strengths:

• Multimodal calculation per shipment and per route with CO2 equivalent by vehicle type, under GLEC, ISO 14083 and SQAS.
• Organisation by contract, client or route, with centralised emission factors and version history.
• Client-level reports, with certificates and data export via API.
• AI data intake for unstructured subcontractor documentation, plus a copilot to detect inconsistencies and analyse deviations.
• ERP integrations and a full corporate footprint on the same platform, not just the transport module.
• Established platform: active clients in 70 countries, more than 30,000 users and 25 million tonnes of CO2e managed, with an average rating of 4.7 out of 5.

Honest limitation: it is not a transport management system. It does not plan routes and does not replace your TMS; it integrates with it.

2. Pledge

Pledge focuses on logistics emissions and international freight forwarding, and has released an open-access freight emissions calculator for forwarders.

Strengths: GLEC alignment, a clear Scope 3 focus and integrations with logistics systems.

Honest limitation: it is built for the international forwarder. It covers less of the organisation's full environmental management.

3. EcoTransIT World

EcoTransIT World is the most cited methodological reference in the sector. It calculates energy consumption, greenhouse gases, air pollutants and external costs for multimodal freight, and is certified with ISO 14083 and the GLEC Framework.

Strengths: technical credibility, a free online calculator and an API for bulk calculation.

Honest limitation: it works as a calculation engine, not a management platform. It does not structure internal processes or retain the documentary evidence an audit needs.

4. BigMile

BigMile calculates and analyses transport emissions at shipment level, verified against ISO 14083:2023 with GLEC as its primary factor source.

Strengths: a very clear logistics focus, scenario modelling and audit-ready reporting.

Honest limitation: implementation is more technical and its reach outside strictly logistics environments is limited.

5. Searoutes

Searoutes stands out in ocean freight. It uses AIS vessel tracking data to match the calculation to the carrier's actual service, and is ISO 14083 certified.

Strengths: accuracy in the ocean mode, an API-first approach and comparison between carrier services.

Honest limitation: its strength is maritime. For a pure road fleet it adds less than the alternatives.

What to choose in your situation

• Road haulier with owned and subcontracted fleet: prioritise TMS integration, subcontractor management and traceability. Manglai and BigMile are the most direct options.
• International multimodal forwarder: Pledge or Searoutes, depending on how much ocean freight your portfolio carries.
• You only need a one-off figure for a client: the free EcoTransIT World calculator solves it without a project.
• You are heading into external verification or public tenders: demand a methodology certified against ISO 14083, attached evidence and version control.
• You also need the corporate footprint and reduction plan under Royal Decree 214/2025: look for a platform that covers both rather than two separate systems.
• You have sites with more than 200 workers: add the workplace sustainable mobility plan to the project, due by 5 December 2026.

How to start without disrupting operations

1. Define what the market is asking for: emissions per shipment, an annual corporate report, auditable data or GLEC-compatible information. The level of demand determines the tool.
2. Inventory your data sources: fuel consumption per vehicle, distance, fleet type, load factors, subcontractor data and TMS or ERP integration.
3. Check whether your system scales: client-level reporting, scenario simulation, automated consolidation and audit evidence. If any of these is missing, manual management is already an operational risk.
4. Choose the data level: primary where it exists (telematics, fuel receipts) and GLEC defaults where it does not, documenting the difference.
5. Close the loop with the business: connect emissions data to cost per route so measurement also serves margin.

For the calculation framework itself, our guide to the GLEC Framework applied to logistics and the comparison of GLEC Framework software are still the reference. If your focus is the full logistics operation rather than the service, see the comparison of logistics carbon footprint software.

FAQs about service carbon footprint software in transport

Is measuring the service footprint mandatory in transport?

No. Regulation (EU) 2026/1030 applies voluntarily to companies that choose to publish transport emissions, and sets out how to do it so figures are comparable. The real obligation arrives by contract, when a shipper reporting under the CSRD asks for the data.

What is the difference between corporate footprint and service footprint?

The corporate footprint totals company emissions over a period. The service footprint assigns emissions to a specific shipment, route or contract, enabling operational and commercial analysis.

Which version of the GLEC Framework applies in 2026?

Version 3.2, published on 23 October 2025. It updates fuel factors, revises marine factors in line with IMO guidance and adds an air pollutant module. Application is expected for 2026 inventories.

Is a spreadsheet enough?

It can work at first in small structures. With multiple routes, subcontractors and traceability requirements, manual management stops being auditable.

How long does implementation take?

It depends on the level of integration and the quality of available data. With digitised systems it can be done in a few weeks; with data scattered across subcontractors, the process takes longer.

To see how this is structured in practice, look at the Manglai service footprint solution or the specific approach for transportation managers.
