What is ISO 14083 and what does it cover?
ISO 14083 is the standard that sets a common method for calculating and reporting greenhouse gas (GHG) emissions from the operation of transport chains, for freight and passengers alike. It answers a plain question: how much CO2 equivalent did it take to move this pallet, container or consignment from the factory to the customer?
Its full title is "ISO 14083:2023 — Greenhouse gases — Quantification and reporting of greenhouse gas emissions arising from transport chain operations". It is the first edition, published in March 2023; on 11 November 2026, iso.org lists it at stage 60.60 (published), with no revision announced. According to its foreword, it was prepared by subcommittee ISO/TC 207/SC 7 (greenhouse gas and climate change management) together with CEN/TC 320 (transport, logistics and services), under the Vienna Agreement between ISO and the European Committee for Standardization (CEN). It cancelled and replaced IWA 16:2015, a workshop agreement that was technically revised throughout "to expand the framework to a methodology". CEN published it in April 2023 as EN ISO 14083:2023.
What the standard takes into account
According to its introduction, published by ISO:
- every mode: road, rail, inland waterway, sea, air, cable car and pipeline, each with its own annex (Annexes A to G);
- hubs, where freight changes vehicle or mode: port terminals, cross-docking sites, distribution centres, road/rail terminals (Annex H);
- empty trips needed for subsequent transport;
- the production and distribution of the energy consumed, on top of its use: this is the well-to-wheel approach, which puts a diesel truck, an electric truck and an LNG-fuelled ship on the same footing;
- refrigerant leakage from vehicle air conditioning and temperature-controlled units (Annex I), a decisive point for fresh-produce exporters.
Offsetting is excluded: the introduction states that this is a standard for calculating emissions only, so offsetting is not part of it. Black carbon is optional (clause 5.2.6).
Key terms
Term | What it means | Why it matters to you |
|---|---|---|
Transport chain | The whole journey of the freight, from its last point of production or transformation (the consignor) to its first non-transport operation (the consignee) | It is the unit of calculation: your dock to your customer’s dock |
Transport chain element (TCE) | A section of the chain in which the freight travels in a single vehicle or passes through a single hub | Each element is calculated separately, then added up |
Transport operation category (TOC) | A grouping of comparable transport operations (same mode, same vehicle or service type) | Emission intensity is calculated per category, not per truck |
Hub operation category (HOC) | In the standard’s words, a "group of hub operations that share similar characteristics" | A port or warehouse transit has its own intensity |
GHG emission intensity | The ratio between emissions and transport or hub activity | The figure to ask your providers for |
Transport activity | Mass carried multiplied by distance (tonne-kilometres for freight) | The data you supply yourself |
The calculation rests on six principles: relevance, completeness, consistency, accuracy, transparency and conservativeness (clause 4). The standard is aligned with the ISO 14064 series and ISO 14067; its introduction says that an intensity per tonne-kilometre calculated under ISO 14083 can serve as primary or secondary data in an ISO 14064-1 inventory or an ISO 14067 product footprint. It also acknowledges, and is in line with, the work of the GHG Protocol, the UNFCCC and the Global Logistics Emissions Council (GLEC) Framework.
Why does it matter to exporters and logistics firms in Morocco?
Because your European customers have to quantify their scope 3, transport is one of its most visible lines, and the EU has made EN ISO 14083:2023 the common method for every transport service that starts or ends on its territory. Exporters receive the question; carriers and freight forwarders will have to answer it using this method.
What your customers ask for
A customer subject to the Corporate Sustainability Reporting Directive (CSRD, Directive (EU) 2022/2464, last amended by Directive (EU) 2026/470, which limits the obligation to companies with more than 1,000 employees and more than EUR 450 million in turnover) reports on its value chain. The leg between your plant and its warehouse appears there, either as transport it bought or as transport upstream of its purchases. Expect requests for tonne-kilometres, modes and, increasingly, intensities calculated under ISO 14083. Our page on CSRD, VSME and ESG questionnaires explains this value-chain pressure.
What Regulation (EU) 2026/1030 changes
Regulation (EU) 2026/1030 of the European Parliament and of the Council of 29 April 2026 "on the accounting of greenhouse gas emissions of transport services", which grew out of proposal COM(2023) 441 (often called CountEmissionsEU), was published in the Official Journal on 12 May 2026. It enters into force on the twentieth day after publication and applies from 2 December 2030. What the text says:
Point | Regulation (EU) 2026/1030 | What it means from Morocco |
|---|---|---|
Scope (Article 1) | Transport services that start or end in the EU, where disaggregated emissions information is calculated and communicated, on a contractual or voluntary basis, for commercial purposes, or where the law requires it | A Tanger Med–Algeciras or Casablanca–Marseille shipment is covered; recital 9 expressly covers departures or arrivals in third countries |
Method (Article 3) | Calculation under EN ISO 14083:2023, as updated | No in-house methods: the standard becomes the common rule |
Data (Article 4) | Primary data first; secondary data allowed if taken from EU databases, compliant third-party databases or a compliant model | Default values will need a recognised source |
Databases (Article 5) | EU main database of default intensities, set up by 2 December 2029, free of charge; maritime values drawn from THETIS-MRV | A public reference for legs where you have no primary data |
EU tool (Article 8) | Implementing acts by 2 June 2030 for a free calculation tool designed for small operators | Useful to small Moroccan road hauliers |
Indicators (Article 9) | Total CO2e per service and at least one common indicator: CO2e per tonne-kilometre for freight, CO2e per tonne for hub transfers | The format of the data you will receive |
Communication (Article 10) | The statement "Greenhouse gas emissions calculated in accordance with Regulation (EU) 2026/1030" and calculation evidence kept available | Figures without that statement will not count as a compliant declaration |
Verification (Articles 12 to 15) | Output data verified by an accredited conformity assessment body, except for SMEs, which may request it; external calculation tools certified for two years | Large forwarders will have their figures verified |
The regulation covers transport operators, transport service organisers, hub operators, data intermediaries, developers of calculation tools and databases, and conformity assessment bodies. It does not oblige anyone to calculate: it governs those who calculate and communicate. An exporter that passes on to its customer transport emissions calculated by others could, however, fall within the definition of a "data intermediary" (Article 2, point 15); have a lawyer assess your position before 2030.
The regulation does not touch the EU Carbon Border Adjustment Mechanism (CBAM), which covers the embedded emissions of goods per installation under its own rules. See our page on CBAM for exporters.
Category 4 or category 9: where does transport go in your GHG inventory?
Transport your company pays for goes in scope 3 category 4, even when it delivers to your customers; category 9 only takes downstream transport you do not pay for. This is the rule of the GHG Protocol Corporate Value Chain (Scope 3) Standard (2011), whose Table 5.7 assigns every transport activity.
Transport situation | Where it goes | Source of the rule |
|---|---|---|
Trucks, forklifts or vessels you own or control | Scope 1 (fuel) or scope 2 (electricity) | Scope 3 Standard, Table 5.7 |
Vehicles leased and operated by you, not already in scopes 1 and 2 | Scope 3, category 8 | Same |
Transport of your purchases between tier 1 suppliers and your plant, in third-party vehicles | Scope 3, category 4 | Same |
Transport services you buy: inbound logistics, outbound logistics to customers, transfers between your sites | Scope 3, category 4 | Same; the standard says purchased outbound logistics is "upstream" because it is a purchased service |
Transport upstream of your tier 1 suppliers (tier 2 to tier 1) | Scope 3, category 1, already in the footprint of purchased goods | Same |
Transport of the fuels and energy you consume | Scope 3, category 3 | Same |
Transport and storage of sold products to the end consumer, not paid for by you | Scope 3, category 9 | Same |
For an exporter, Incoterms settle it: when you buy the main carriage to the customer, it goes in category 4; when your customer buys it from your plant or your port of loading, it goes in category 9. The same product can therefore change category from one contract to the next, so keep a written rule per customer in your inventory file.
ISO 14064-1:2018 places the same emissions in its category 3, "indirect GHG emissions from transportation". Our ISO 14064-1 requirements guide gives the full mapping, and Annex R of ISO 14083 itself compares its categorization with the GHG Protocol’s. ISO 14083 calculates; the GHG Protocol and ISO 14064-1 tell you where to report the result.
For a product footprint under ISO 14067:2018, the same calculations feed the transport stages of the life cycle: see our comparison of GHG inventories, LCA and product carbon footprints.
How do you calculate transport chain emissions under ISO 14083?
You split the chain into elements, obtain an emission intensity for each one, multiply it by the activity (tonne-kilometres for a leg, tonnes transferred for a hub) and add everything up. The standard sets out these steps in clauses 7 to 12, first at the level of operation categories, then for each element and finally for the whole chain.
The steps
- Map the chain. From your dock to the consignee’s dock, list every vehicle and every hub. Example: a fresh-produce exporter in the Souss region ships by refrigerated truck to Tanger Med; the trailer crosses by ro-ro vessel, then continues by road to a warehouse in southern France. That makes at least five elements: road, port terminal, sea, port terminal, road.
- Assign each element to an operation category. Long-haul refrigerated truck, ro-ro vessel on a given route, container terminal: each category gets its own intensity.
- Establish the emission intensity of each category, using one of the standard’s four options (table below).
- Calculate the activity of each element: the mass of your shipment multiplied by the distance used. The standard provides for a distance adjustment factor (clause 5.4.4 and the mode annexes): ask which distance was used and whether the factor was applied.
- Allocate when your freight shares a vehicle: between freight and passengers on a mixed ro-pax ferry (Annex G), between temperature-controlled and ambient freight (clause 5.6.4).
- Add up the elements to get the chain’s emissions, then the intensity of the whole chain.
- Report: at organizational level (boundaries, report, periodicity) or at the level of a service, with a description of the method and disclosure of any modelled or default data used (clause 13).
The four options for obtaining an intensity
ISO 14083 option (clause 7.2) | Principle | When to use it | Expected reliability |
|---|---|---|---|
A — Primary data | Fuel or electricity actually consumed and actual activity of the category | Your own fleet, a carrier that tracks its consumption | Highest |
B — Model | Calculation by a model that reflects vehicle and trip parameters (Annex M) | No measured consumption, but a known trip and vehicle | Medium, depending on the model |
C — Default value | Value taken from a database of default intensities (sources: Annex Q) | Legs with no data at all, a first inventory | Lowest, to be replaced over time |
D — Operator value | Intensity supplied by the subcontracted carrier | Sea, air, parcel and groupage freight | As good as the operator’s calculation: ask for its option and sources |
Regulation (EU) 2026/1030 follows the same hierarchy: primary data come first, and default values are accepted only from recognised sources. This guide deliberately gives no numerical intensity: each value must come from a cited source, with its year.
Three points specific to exports from Morocco
- Refrigeration. For fruit, vegetables, seafood or dairy, the fuel burned by refrigeration units and refrigerant leakage come on top of traction fuel. The standard covers both (clause 5.6.4 and Annex I): check that they appear in the figures you receive.
- Hubs. Passing through a port terminal, a bonded warehouse or a groupage platform has its own intensity, per tonne transferred. A calculation that only counts moving legs is incomplete. Repackaging at hubs has its own annex (Annex O).
- Electricity. For electric traction or hubs, Annex J of the standard sets the conditions for a market-based approach; otherwise a location-based value is used, as in the scope 2 of your GHG inventory to ISO 14064.
What data should you ask carriers and freight forwarders for?
Ask for emissions calculated under ISO 14083:2023, per shipment or per operation category, with the calculation option and the sources of each value. You supply the activity (masses, origins, destinations, dates); they supply the intensities and evidence of their method.
Data | Who holds it | Evidence |
|---|---|---|
Mass shipped per consignment, origin, destination, date | You (logistics, sales administration) | Delivery notes, bills of lading, CMR consignment notes |
Modes and vehicles used, hubs passed through | Carrier, freight forwarder | Transport plan, transit documents |
Distance used per leg and any distance adjustment factor | Carrier | Method statement |
Well-to-wheel emission intensity per operation category | Carrier, shipping line, hub operator | Emissions statement and method statement |
Calculation option (A, B, C or D) and sources of default values | Carrier | Method statement, references of databases used |
Treatment of refrigeration and refrigerant leakage | Refrigerated carrier | Method statement |
Who pays for each leg (for category 4 or 9) | You (purchasing, finance) | Incoterms, freight invoices |
Checklist to attach to your transport tenders
The same data serve three purposes: your GHG inventory, the transport stage of your product carbon footprints, and your reduction plan, where mode choice, load factor and energy type are concrete levers. Our guide to industrial decarbonisation in Morocco puts them into an overall plan.
Which mistakes should you avoid, and what can you claim?
Most mistakes come from a vague boundary: a forgotten leg, an ignored hub, two methods mixed, the same transport counted twice. On the communication side, ISO 14083 lets you state calculated emissions, not neutrality.
Mistake | Consequence | Fix |
|---|---|---|
Mixing tank-to-wheel and well-to-wheel figures | Distorted comparison between modes and energies | Require the well-to-wheel calculation set by the standard everywhere |
Counting only the sea leg | Underestimation: road pre- and on-carriage and terminals left out | Map the full chain, dock to dock |
Counting the same transport in category 4 and category 9 | Double counting, picked up at verification | A written rule per Incoterm and per customer |
Keeping default values year after year | No record of the carrier’s real progress | A plan to replace them with primary or operator data |
Citing IWA 16:2015 in a tender | Withdrawn reference | Cite ISO 14083:2023 |
What you can and cannot say
ISO 14083 is not a management system standard: a company cannot be "ISO 14083 certified". You can state that emissions were calculated under ISO 14083:2023 and, if an inventory that includes them was verified, say so with the boundary and assurance level of the opinion. Verification of a GHG inventory follows ISO 14064-3:2019: see our guide to ISO 14064-3 verification.
A "carbon-neutral delivery" obtained by buying credits is not an ISO 14083 result, since the standard excludes offsetting. Towards EU consumers, Directive (EU) 2024/825 has, since 27 September 2026, banned in all circumstances any claim that a product has a neutral, reduced or positive environmental impact because emissions were offset. If your European customer reuses your data on packaging or a web shop, it carries that risk, and you will get the question: read our article on Directive 2024/825 and environmental claims. ACG’s position does not change: reduce first, and claim only what you can prove.
