The transport buyer wants CO₂ on the invoice.

Your fuel cards and invoices already hold the answer.

Transport is the first line big companies attack in their Scope 3 reporting — and they're starting to pick carriers by who can deliver the number. The fuel, the vehicles and the subcontractors are already in your books. Wellfish turns them into climate data you can sell with.

02How it works

From fuel card to climate report — in three steps.

Diesel, vehicle purchases and subcontracted transport already flow through the accounting system. Wellfish turns the transactions into a climate calculation you can show the transport buyer.

Connect your bookkeeping

Wellfish reads transactions directly from the accounting system — Fortnox, Visma, Hogia and more. The fuel, vehicles and subcontractors are already there.

AI classifies — you approve

Every transaction is matched to emission factors and GHG categories: fuel, vehicles, purchased transport. You review and approve — which is why the number holds up to scrutiny.

The report is ready

A climate calculation per the GHG Protocol, ready to send to the transport buyer, the procurer or the bank — and to follow up next year.

03The emissions

Haulier or forwarder — the breakdown looks completely different.

A haulier with its own fleet is dominated by its own fuel. An asset-light forwarder has almost everything in Scope 3. This is what a Swedish haulier looked like in 2024:

77.3 %

Fuel (Scope 1)

Diesel in own trucks. The factor per litre changes year by year with the fuel mandate.

15.7 %

Vehicles (manufacturing)

The trucks' and trailers' manufacturing — never shows in the tank, only in the books.

3.5 %

Electronics & IT

Vehicle electronics and fleet equipment.

3.6 %

Other

Packaging, commuting, warehouse and office.

~93 %

Forwarder: Scope 3

At a global logistics group, almost everything is purchased transport. The more asset-light, the bigger the black hole.

Breakdown from a Swedish haulier's public 2024 climate report (~5,500 tonnes CO₂e total) and Rhenus Group 2024. Rule of thumb: 1 m³ of fossil diesel ≈ 3 tonnes CO₂e over the full life cycle.

04The systems

Connects to the systems you already use.

The accounting system is the data source — so everything starts with a connection. Most common in transport and logistics:

05The pitfalls

Four traps transport companies walk into.

We see the same mistakes again and again. All four are avoidable.

Fuel control without climate control

You know what the diesel costs but not what it emits. When the customer asks for CO₂ data there's no answer — and the bid gets sorted out.

The vehicles that never get counted

Almost 16 % of the footprint sits in the trucks' manufacturing. Whoever only counts the tank misses one tonne in six.

The forwarder's black hole

Purchased transport is Scope 3 — up to 93 % of the footprint for asset-light companies. Without subcontractor numbers the report is mostly empty space.

The wrong factor on the fuel

The fuel mandate changes the factor per litre, year by year. A spreadsheet with 2022's factor gives the wrong number in 2026 — and fails a customer audit.

06The payoff

What you get.

Climate data to sell with

Answer the transport buyer's form with reviewed data — and turn the number into a sales argument instead of a risk.

The whole footprint, not just the tank

Fuel, vehicles, electronics and purchased transport in one calculation — per the GHG Protocol.

The right factors, every year

Emission factors are kept up to date — the fuel mandate's swings land correctly without you touching a spreadsheet.

Proof of improvement

Switched fuels or electrified? Show the reduction in black and white, year on year — that's how tenders are won.

07Worked example

What it looks like in practice.

A worked example built on the benchmarks — a haulier with 25 trucks on Fortnox:

Starting point

The biggest customer wants climate data for its purchased transport, with a deadline

Quick estimate

~150 m³ diesel per year × 3 ≈ 450 tonnes CO₂e — and that's just the fuel

Connection

Fortnox connected; the AI classifies fuel cards, vehicle purchases and subcontractors

Review

The finance lead approves the categories — hours, not weeks

Result

Climate calculation per the GHG Protocol — the customer's form answered with data

The surprise

Vehicle purchases are the second-biggest line — bigger than everything except the diesel

Worked example based on public benchmarks — not a single customer company.

“The automation through integrations with invoicing systems, combined with Wellfish AI, streamlines the work considerably.”

09FAQ

Questions we often get

Can you report CO₂ per shipment?

Wellfish calculates the company's climate footprint from the books — the number most forms and tenders require. Per-shipment data needs TMS data and is a different calculation, but the company number is the foundation that makes it credible.

We run both our own trucks and subcontractors — how is that handled?

Own fuel is classified as Scope 1, purchased transport as Scope 3. Both come from the same invoice flow and are reported separately — exactly as the GHG Protocol requires.

The fuel mandate keeps changing — how does that affect the number?

Emission factors are kept up to date, so the fuel's climate impact is calculated with the right factor for the right period. That's why numbers can be compared between years without you adjusting anything.

How long does it take to get started?

Connecting the accounting system takes a few minutes. A finished, reviewed climate calculation is typically ready within about five days of connecting.

What does it cost?

Fixed price per engagement — from SEK 25,000 per year, depending on volume and number of systems. The demo account is free and the preview calculation of your first 500 records is included. Current pricing is on wellfish.se/en/pricing.

Which systems do you support?

A dozen-plus Swedish accounting systems — including Fortnox, Visma, Hogia, EMCE and Marathon by Kase. If yours is missing, records can be uploaded manually.
