GLEC logistics carbon footprint: the emissions of every shipment and a report for every client
A GLEC project in Dcycle takes your shipments, your fuel consumptions and your hubs, through a template or the API. Every shipment comes out with its tonne-km, its intensity in g CO₂e/tkm and its kg CO₂e, and for each client you download the GLEC v3.0 report for the period they ask for.
- Emissions per shipment, with its TOC
- Real fuel use of your vehicles
- GLEC v3.0 report per client
- Upload by template or API

What you are asked for
Who asks for your transport emissions and where it gets stuck
Your shipper clients need your emissions for their Scope 3 (categories 4 and 9), and more and more of them want them calculated to GLEC or ISO 14083.
Shipper client The emissions of their shipments over a period, to GLEC, for their Scope 3. Thousands of that client’s trips filtered by hand and the calculation redone every time. You pick the client and dates and download their GLEC v3.0 report as a PDF with your company logo.
Client procurement team Shipment-by-shipment detail in a format they can load into their system. Every client wants a different format. Line-by-line export in CSV, Excel or JSON, with one file per client if you need it.
Auditor or verifier Which figure is real and which is a default value or an estimate. A spreadsheet does not tell a measured fuel figure from an average. Estimated values (distance, load, TOC or intensity) carry a flag on each shipment, and the report separates primary and secondary data.
Operations Loading the month’s trips without stopping the operation. Exporting from the TMS, cleaning columns and pasting into another sheet. An import template for shipments and fuel consumptions, or an API connection from your system.
Management Which lanes and which vehicles drive the emissions. The data sits in the TMS, the fuel cards and the hubs, separately. Shipments, fuel and hubs in one project, and Leia answers questions about your shipments and their emissions.

Product
Dcycle’s GLEC project, from trips to report
Shipments
Every shipment with its tonne-km and CO₂e
The shipments list shows client, date, distance, load, tonne-km, TOC, whether the transport is owned or subcontracted, the intensity in g CO₂e/tkm and the kg CO₂e. Opening a shipment shows its detail: movement ID, metrics, who uploaded it and which file it came from.
- Estimated distance, load, TOC or intensity flagged
- Bulk TOC editing, with the emissions recalculated
- Leia answers questions about your shipments
Data
Shipments, fuel consumptions and hubs in one project
The Data tab groups your shipments, your vehicles’ fuel consumptions and your hubs, each with its record count. Fuel records carry plate, country, date, quantity, fuel and TOC, and they are the primary data used to calculate your fleet’s intensity.
- Diesel, biodiesel blends, HVO, LNG, LPG, electric and more
- Hubs with their categories (HOC)
- Upload by template or through the logistics API
Reports
Each client’s GLEC v3.0 report, as a PDF
In Reports you pick the client, a start and end date within the same year and the language, and the report opens: total footprint, Scopes 1, 2 and 3 (fuel, cleaning and subcontracted) and a table per TOC with WTW GHG intensity, client tonne-km, WTW emission, fuel, share of empty kilometres and kilometres travelled. Inside the project the PDF is also saved to Files.
- Report in English, Spanish, German, Italian, Portuguese or Catalan
- Smart Freight Centre seal on the cover
- Detailed export in CSV, Excel or JSON

What it is
What the GLEC Framework is and what it measures
Smart Freight Centre’s method to calculate and report the greenhouse gas emissions of freight transport and logistics hubs, across all modes.
From the GHG Protocol to GLEC 3.0- v3
GLEC Framework version
Aligned with ISO 14083:2023 and with the GHG Protocol for corporate reporting.
- 4
transport modes
Road, rail, sea and air, plus hubs (warehouses and transhipment centres).
- WTW
well-to-wheel
The sum of the emissions from producing the fuel (WTT) and burning it in the vehicle (TTW).
The terms you will see in the report
HOC
Hub Operation Category: the same for hubs, by type of activity.
Tonne-km (tkm)
Load carried times distance travelled. The activity unit of freight transport.
Emission intensity
Grams of CO₂e per tonne-km. Multiplied by a shipment’s tkm it gives its emissions.

How it is calculated
How to calculate your logistics footprint in three steps
You do not need to be a sustainability expert: you upload the activity and Dcycle applies the GLEC method.
- 1Create your GLEC projectFrom Projects you pick the GLEC logistics template and get a workspace with data, tasks, files and reports.
- 2Upload shipments, fuel and hubsWith the import template or through the API. Where the actual distance is missing, the activity distance is calculated: shortest feasible distance (SFD) for road, rail and sea, great circle distance (GCD) for air.
- 3Review and download the reportCheck pending or estimated shipments and download each client’s GLEC v3.0 report for the period they ask for.
Primary and secondary data
| Data type | What it includes | When it is used |
|---|---|---|
| Primary | Fuel consumption of your vehicles, load carried and number of trips | Whenever you upload it: it is what the most demanding clients ask for |
| Secondary | GLEC Framework default emission intensity values | When the actual fuel figure is missing, for example on subcontracted lanes |

Accreditation
Dcycle, accredited by Smart Freight Centre
Smart Freight Centre, the organisation behind the GLEC Framework, has accredited Dcycle’s calculation as conforming with GLEC and ISO 14083.
Dcycle’s accreditationWhat it means
The method Dcycle uses to calculate the well-to-wheel transport emissions of your shipments has been reviewed against the GLEC Framework.
What your client sees
The GLEC v3.0 report carries the Smart Freight Centre seal and the reference to ISO 14083:2023 on its cover.
What it does not replace
The accreditation covers the calculation method. Your data is not verified by a third party unless you commission that verification, and the report says so.
How the report splits your emissions by scope
| Scope | What it includes |
|---|---|
| Scope 1 | Combustion (TTW) in your own vehicles and fuels burned at your hubs |
| Scope 2 | Electricity bought for your hubs |
| Scope 3 | Fuel production (WTT), vehicle cleaning and subcontracted transport |

FAQ
Frequently asked questions about GLEC logistics carbon footprints
What is the GLEC Framework?
It is Smart Freight Centre’s method to calculate and report the greenhouse gas emissions of freight transport and logistics hubs by road, rail, sea and air. Version 3 is aligned with ISO 14083:2023 and with the GHG Protocol.
How do GLEC and ISO 14083 relate?
ISO 14083:2023 is the international standard for quantifying and reporting the emissions of transport chains. GLEC v3 puts it into practice with default values, operation categories and guidance per mode. A calculation that conforms with GLEC v3 conforms with ISO 14083.
Why do my clients ask for emissions to GLEC?
Because the transport they buy from you is part of their Scope 3 (GHG Protocol categories 4 and 9), which they have to report under the CSRD or in their own climate disclosures. Asking for GLEC lets them compare carriers on the same method. The European Commission’s CountEmissionsEU proposal also takes ISO 14083 as its reference method.
What data do I need to upload?
Your shipments (client, date, origin and destination or distance, load and TOC) and, if you have them, your vehicles’ fuel consumptions (plate, date, fuel and quantity) and your hubs. With real fuel data the intensity comes from your own fleet; without it the GLEC Framework default values are used.
What is a TOC?
A Transport Operation Category: a group of transport operations with similar characteristics, such as a 12 to 20 t rigid truck running on diesel or a container vessel on a given trade lane. Dcycle works with more than 300 TOCs across road, rail, sea and air.
What is the difference between WTW, WTT and TTW emissions?
TTW (tank-to-wheel) are the emissions from burning the fuel in the vehicle. WTT (well-to-tank) are those from producing and distributing it. WTW (well-to-wheel) is the sum of both, and it is the figure GLEC asks for.
Can I give each client only their own emissions?
Yes. The GLEC v3.0 report is generated per client and per period within the same calendar year, with your company logo. For shipment-by-shipment detail there is the CSV, Excel or JSON export, with one file per client if you choose.
What about subcontracted transport?
Each shipment says whether it is owned or subcontracted. Subcontracted emissions appear in the report under Scope 3. Without the subcontractor’s fuel data, they are calculated with the default intensity of its TOC.
Can I connect my TMS through an API?
Yes. Dcycle has a logistics API to upload shipments and fuel consumptions and to download results, documented at docs.dcycle.io. You can also use the import template.
