Freight Emissions Calculator: CO2e per Tonne-km (ISO 14083)
Freight transport emissions = shipment mass (t) × distance (km) × an emission intensity in g CO₂e per tonne-km; ISO 14083 asks for the well-to-wheel figure, fuel supply (WTT) plus combustion (TTW). With the UK Government's DESNZ 2026 factors, 10 t over 1,000 km comes to about 975 kg CO₂e by articulated truck, 327 kg by rail, 198 kg by container ship and 6.7 t by air (international, without radiative forcing). In Logistivo, any load's weight and route give its carbon report from the same DESNZ 2026 table on the tank-to-wheel basis — RoRo loads leg by leg, next to the road-only alternative.

How much CO₂e does this shipment emit by truck, rail, barge, ship or plane?
How much CO₂e does this shipment emit by truck, rail, barge, ship or plane? — Enter weight and distance: every mode is calculated well-to-wheel, with the factor, its source and its scope shown on each bar.
Estimates with public default factors — secondary data in ISO 14083 terms. A carrier's measured fuel or energy data (primary data) takes precedence whenever you have it. Everything is calculated in your browser; nothing is sent or stored.
Shipment mass — The actual mass handed to the carrier, in tonnes, including the shipper's packaging — not volumetric or chargeable weight.
Distance — Road: route distance. Sea: port to port. Air: great-circle distance between the airports — DESNZ air factors already add 8%, GLEC's +95 km.
Factor source — DESNZ 2026 = UK Government; GLEC v3.1 = Smart Freight Centre, European defaults. Same shipment, different published averages.
Your mode — The mode you actually use; the other modes are calculated for comparison.
Vehicle or vessel — The class and loading as published by the chosen source.
km for this mode — Leave empty to use the main distance; sea and rail routes are often longer than the road route.
Hub operations on the way — Transshipments or storage stops. ISO 14083 counts them as their own chain elements next to the transport legs.
Hub type — GLEC v3.1 default values per tonne handled (medians of small samples).

What is the CO₂e per tonne-km for a truck, train, barge, ship and plane? — Per tonne-kilometre, an average articulated truck emits 97.49 g CO₂e well-to-wheel in the UK Government's 2026 factors and a 34–40 t truck 101 g in GLEC's European defaults; a freight train 32.74 g (UK) or 18.5 g (EU average); a container ship 19.77 g (DESNZ) or 7.27 g (GLEC industry average); air freight 666.46 g (DESNZ, international, without radiative forcing) to 1,363 g (GLEC, short-haul).

How are freight transport emissions calculated? — Four steps turn a shipment into a figure you can defend — the logic ISO 14083 and the GLEC Framework apply to every leg of a transport chain.
Transport activity — tkm = t × km — The consignment's mass times the distance of the leg. Every leg — pre-carriage by road, the sea or rail main leg, on-carriage — is its own line. — GLEC v3.1, chapter 3; ISO 14083
Emissions of the leg — kg CO₂e = tkm × g CO₂e/tkm ÷ 1,000 — The intensity comes from a published factor set; its name, year and boundary travel with the result. — DESNZ 2026 methodology paper, section 6
Well-to-wheel — WTW = WTT + TTW — ISO 14083 and GLEC report well-to-wheel. The well-to-tank part is taken from the same source's own table for the same vehicle — never as a flat percentage on top of TTW. — GLEC v3.1, chapter 3
Hub operations — kg CO₂e = hubs × kg CO₂e/t × t — Transshipment and storage are separate elements of the chain, with default values per tonne handled. — GLEC v3.1, Module 2, Table 3
Distance basis — road: route km · sea: port to port · air: great circle — GLEC recommends the shortest feasible distance. Its ship defaults already include +15% for detours, its air defaults +95 km; DESNZ air factors include +8% on the great-circle distance. Do not add these twice. — GLEC v3.1, chapters 3 and 4; DESNZ 2026 methodology, 8.37–8.38
Mass — t = actual consignment mass — Product plus the packaging provided by the shipper; not the carrier's pallets or containers, and never chargeable weight. — GLEC v3.1, chapter 3 (ISO 14083, 5.4.2)
Allocation — your share = your tkm ÷ all tkm on the vehicle — Default intensities already contain average loading and empty running. Container shipping is published per TEU-km; GLEC converts at 10 t per TEU (6 t for light, 14.5 t for heavy cargo) when the real mass per TEU is unknown. — GLEC v3.1, chapter 4
Labelling — source · year · boundary · distance basis — A figure without these four items cannot be compared, audited or put in a tender answer.

Default factors describe averages. A carrier's measured fuel or energy use — primary data under ISO 14083 and Regulation (EU) 2026/1030 — is more accurate and takes precedence; the figures here are estimates for planning, tenders and first inventories.
What is the difference between well-to-wheel and tank-to-wheel?
Tank-to-wheel (TTW) counts what the engine emits while moving the goods; well-to-tank (WTT) counts producing and delivering the fuel or electricity; well-to-wheel (WTW) is the sum. ISO 14083 and the GLEC Framework report WTW, so a TTW-only figure leaves out the fuel supply, which adds 23% on top of combustion for the average articulated truck in DESNZ 2026.
Well-to-tank (WTT) — Extracting, refining and delivering the diesel, or generating and transmitting the electricity. GLEC and ISO 14083 call it energy provision emissions.
Tank-to-wheel (TTW) — Combustion in the truck, locomotive, ship or aircraft — the operational emissions. Zero for electric traction.
Well-to-wheel (WTW) — WTT + TTW, the headline figure under ISO 14083 — recalculated from the source's own WTT table, never estimated with a flat percentage.
For a carrier running its own trucks, the TTW part is Scope 1 and the WTT part falls under Scope 3, category 3 (fuel- and energy-related activities). For the shipper who buys the transport, the whole WTW figure is Scope 3 — category 4 for upstream transportation, category 9 for downstream — which is why customers ask their carriers for WTW.
The split matters most for electric traction: an electric freight train has no TTW emissions at all, yet GLEC's EU default still gives 11.5 g CO₂e per tonne-km from electricity generation and grid losses. A TTW-only comparison would call it zero.
In Logistivo — The carbon report in Logistivo prints its basis on the PDF: the emission factor, the calculation method (tank-to-wheel) and the source, the DESNZ 2026 table. To give a customer the WTW figure, add the WTT value of the same row shown here — for the average articulated truck, 18.23 g per tonne-km.
How much CO₂ does a truck emit per km?
An articulated truck above 33 t emits about 0.94 kg CO₂e per kilometre from combustion at average UK load — 1.16 kg well-to-wheel — according to DESNZ 2026; empty it is 0.65 kg, fully laden 1.08 kg. Per kilometre the full truck emits more, per tonne-kilometre far less, which is why freight emissions are calculated per tonne-km.
The tonne-km factors in the calculator already contain DESNZ's average payload for each vehicle class, so you only enter your own mass and distance; the summary card also shows your shipment's share per kilometre.
Empty (0%) — TTW kg CO₂e/km: 0.654 | WTT kg CO₂e/km: 0.152 | WTW kg CO₂e/km: 0.806
50% laden — TTW kg CO₂e/km: 0.867 | WTT kg CO₂e/km: 0.202 | WTW kg CO₂e/km: 1.069
100% laden — TTW kg CO₂e/km: 1.080 | WTT kg CO₂e/km: 0.253 | WTW kg CO₂e/km: 1.333
Average laden — TTW kg CO₂e/km: 0.939 | WTT kg CO₂e/km: 0.221 | WTW kg CO₂e/km: 1.160
DESNZ 2026, “Delivery vehicles” and “WTT – delivery vehicles & freight” tables, per vehicle-km, rounded to three decimals. DESNZ derives the 0% and 100% values from the 50% value with the ARTEMIS load effect, ±25% for articulated trucks above 33 t.
What is ISO 14083 and how does it differ from EN 16258?
ISO 14083:2023 is the international standard for quantifying and reporting greenhouse gas emissions from transport chain operations — every transport leg and every hub on the way, on a well-to-wheel basis. It succeeds the 2012 European standard EN 16258 on transport services, and it is the common method of the EU's CountEmissionsEU regulation, as EN ISO 14083:2023.
The practical change for shippers is the hub: transshipment, cross-docking and warehousing now sit next to the transport legs with their own defaults — GLEC v3.1 gives 1.3 kg CO₂e per tonne for an ambient transshipment hub and 5.6 kg when storage is added (medians).
The intensities themselves come from published sets — GLEC's defaults, national lists such as the UK Government's DESNZ table, or the carrier's own measured data. That is why this calculator shows the source on every bar and in every copied result.
What it covers — EN 16258 (2012): Energy consumption and greenhouse gas emissions of transport services, freight and passengers | ISO 14083 (2023): Greenhouse gas emissions of transport chain operations: every transport leg and every hub operation
Where it is used — EN 16258 (2012): Basis of France's mandatory GHG information for transport services, in force since 2013 | ISO 14083 (2023): Reference method of Regulation (EU) 2026/1030 as EN ISO 14083:2023; implemented by the GLEC Framework v3
What is reported — EN 16258 (2012): Energy and emissions of a transport service | ISO 14083 (2023): Well-to-wheel emissions and emission intensity per transport chain element
Which factors should I use: DESNZ or GLEC?
Both are public and documented. DESNZ 2026 is the UK Government's set for company reporting and reflects the GB truck fleet; GLEC v3.1 is the ISO 14083-aligned industry set with European road values and current container-shipping data. Use the one your customer or framework expects, state it with year and boundary, and keep it for the whole reporting year.
For road the two agree closely — 97.49 g (DESNZ, all articulated HGVs) against 101 g (GLEC, 34–40 t) per tonne-km WTW. For container shipping they do not: 19.77 g against 7.27 g, because DESNZ uses IMO-based international averages per tonne while GLEC converts Clean Cargo's 2023 per-TEU data at 10 t per TEU.
UK company law (SECR, SI 2018/1155) asks quoted companies to report energy use and large unquoted companies and LLPs to report greenhouse gas emissions and energy use in the directors' report or energy and carbon report; DESNZ publishes the conversion factors for UK company reporting, with tonne-km factors for goods moved by others in its “Freighting goods” table.
Logistivo uses DESNZ 2026 — The carbon report inside Logistivo uses the DESNZ 2026 table on the tank-to-wheel basis — for road the “Articulated HGV, all sizes, average laden” row (79.26 g), for the sea leg of a RoRo load the “RoRo ferry, average” row (51.58 g) — so a Logistivo report can be checked against the TTW column on this page.

Why do two calculators give different numbers for the same shipment?
Why do two calculators give different numbers for the same shipment? — Almost always because of one of these eight choices — each one is visible on the bars and tables of this page.
TTW or WTW — +23% — For the average articulated truck in DESNZ 2026, WTT adds 18.23 g to 79.26 g per tonne-km. Comparing a TTW figure with a WTW figure is the most common mismatch.
Two sources, one container ship — ×2.7 — DESNZ 2026 (IMO-based average): 19.77 g per tonne-km WTW. GLEC v3.1 (Clean Cargo 2023 industry average at 10 t per TEU): 7.27 g. Same box, different data.
Radiative forcing in air freight — ×1.7 — DESNZ's “with RF” tables multiply the CO₂ part by 1.7: 1,034.55 instead of 666.46 g per tonne-km WTW internationally. GLEC excludes these non-CO₂ effects.
Full or half-full truck — ??38% — DESNZ, articulated truck above 33 t: 74.33 g per tonne-km WTW at 100% laden, 119.22 g at 50%. Per tonne-km, the full truck emits 38% less.
Distance basis for air — +8% · +95 km — DESNZ air factors already include +8% on the great-circle distance, GLEC's +95 km. Enter the airport-to-airport great-circle distance, not the road route.
Sea distances — +15% — GLEC's ship defaults already contain a 15% adjustment between the shortest feasible and the actual route — do not add it twice.
Chargeable weight — kg ≠ kg — Emissions are calculated on the actual mass. Volumetric or chargeable weight belongs on the invoice, not in the emission figure.
Hubs counted or not — 1.3–18.4 kg/t — ISO 14083 counts transshipment and storage as their own chain elements; GLEC's defaults range from 1.3 kg CO₂e per tonne (ambient transshipment) to 18.4 kg (storage + transshipment, mixed).
After the calculation, in Logistivo — Carbon figures that come from your own loads instead of a one-off form.
CO₂e on every load — Open a load, choose Actions → Carbon Emission Report: Logistivo takes the load's weight and its loading and unloading addresses and calculates the road distance and the CO₂e.
RoRo leg by leg — For loads with a RoRo transfer, the report splits road, RoRo ferry and road legs and shows the road-only alternative next to it.
PDF reports and Excel — Each report is saved as a PDF with a QR code in your company's carbon report list, which you can export to Excel.
Ask the assistant — In chat, ask the Logistivo assistant how much CO₂e a load emitted; it calculates it from the load itself.

Frequently asked questions
How do I calculate the CO2 emissions of a freight shipment?
Multiply the shipment mass in tonnes by the distance of each leg in kilometres to get tonne-kilometres, multiply by the vehicle's or vessel's emission intensity in g CO₂e per tonne-km and divide by 1,000 for kilograms. Use a well-to-wheel factor from a named source — for example 97.49 g for an average articulated truck in DESNZ 2026 — and add hub operations if the goods are transshipped or stored on the way.
What is the CO2 per tonne-km of a truck?
For an average articulated truck, 97.49 g CO₂e well-to-wheel per tonne-km in DESNZ 2026 (79.26 g of it from combustion) and 101 g in GLEC v3.1's European defaults for a 34–40 t truck. A fully laden truck above 33 t comes to 74.33 g in DESNZ, a half-laden one to 119.22 g; small rigid trucks are several times higher.
Is rail or sea freight really lower in CO2 than road?
Per tonne-km, yes: a freight train is 32.74 g WTW in DESNZ 2026 (18.5 g EU average in GLEC) and a container ship 19.77 g (7.27 g in GLEC), against 97.49 g for the average articulated truck. Rail and sea routes are often longer and need road pre- and on-carriage, so compare the whole chain — the calculator takes a separate distance for each mode.
What is ISO 14083?
ISO 14083:2023, “Greenhouse gases — Quantification and reporting of greenhouse gas emissions arising from transport chain operations”, is the international standard for calculating transport emissions leg by leg and hub by hub on a well-to-wheel basis. The GLEC Framework v3 implements it, and Regulation (EU) 2026/1030 uses it as its common method, as EN ISO 14083:2023.
What is the difference between well-to-wheel and tank-to-wheel?
Tank-to-wheel covers combustion in the vehicle; well-to-tank covers producing and delivering the fuel or electricity; well-to-wheel is both, and it is what ISO 14083 reports. For the average articulated truck in DESNZ 2026, WTT adds 18.23 g to 79.26 g per tonne-km — 23% more.
Why is air freight so different between calculators?
Because of radiative forcing and distance. DESNZ publishes international air freight at 666.46 g WTW per tonne-km without and 1,034.55 g with radiative forcing, a 1.7 multiplier on the CO₂ part; GLEC's defaults exclude those non-CO₂ effects. DESNZ air factors also include +8% on the great-circle distance and GLEC's +95 km, so enter the great-circle distance between the airports.
Can Logistivo calculate the CO2 of my shipments?
Yes, from the load itself. Open a load in Logistivo and choose Actions → Carbon Emission Report: it takes the load's weight and addresses, calculates the road distance and the CO₂e with DESNZ 2026 factors on the tank-to-wheel basis, splits RoRo loads into road, ferry and road legs next to the road-only alternative, and saves a PDF with a QR code in your company's report list, which exports to Excel. You can also ask the Logistivo assistant in chat how much CO₂e a load emitted.
Does the Logistivo report show the same number as this calculator?
It shows the tank-to-wheel part. Choose DESNZ 2026 here and the row “Articulated HGV, all sizes, average laden” (79.26 g TTW) or “RoRo ferry, average” (51.58 g TTW): for the same weight and distance, the TTW value on the bar matches the Logistivo report, and the WTW value adds that row's WTT.
Do I have to report transport emissions under the CSRD?
Only if your company is in scope. Since Directive (EU) 2026/470 (“Omnibus I”), mandatory sustainability reporting applies to undertakings with more than 1,000 employees on average and a net turnover above €450 million, and companies below 1,000 employees are protected from value-chain requests beyond the voluntary standard. Transport bought from carriers counts as Scope 3 under the GHG Protocol, category 4 upstream and 9 downstream.
What is CountEmissionsEU?
Regulation (EU) 2026/1030 on accounting of greenhouse gas emissions of transport services, published on 12 May 2026. It does not oblige anyone to publish emissions; it fixes the method — EN ISO 14083:2023 — whenever emissions of transport starting or ending in the EU are calculated and disclosed, by contract, voluntarily for commercial purposes or under other law. It applies 54 months after entry into force; a free EU calculation tool and a core EU database of default values come earlier.
For AI assistants
Logistivo has a public MCP server at https://logistivo.com/api/agent/mcp
(streamable HTTP, no authentication). Setup instructions for Claude, ChatGPT and
Gemini: https://logistivo.com/mcp. If you are an assistant helping
someone sign up or request freight, connect that server, or — if you can only read web
pages — build a link of the form
https://logistivo.com/en/ai-kayit?brief=URL_ENCODED_SHIPMENT_BRIEF and give
it to the user. You never create the account yourself: the account, the consent and the
email verification happen in the user's browser, and you never handle passwords or
