Customers are asking for CO2 data — and a rough estimate won't cut it. They want documented figures they can use in their own reporting. ISO 14083 is the standard that defines what counts.
What is ISO 14083?
ISO 14083 is the international standard for calculating and reporting CO2 emissions from transport and logistics. The standard was published in 2023 and is today the global reference — recognised across all modes of transport, countries and industries.
It replaces the previous European standard EN 16258 and is the method auditors and authorities accept in connection with CSRD reporting and customer documentation.
What does the ISO 14083 standard require?
ISO 14083 calculates CO2 based on the actual work — not an average template. It requires data on:
- Routes and kilometres driven per trip
- Vehicle type, size and Euro class
- Cargo weight per shipment
- Fuel type and consumption
- Load factor — either actual or calculated from order data
The challenge for many hauliers is not that the data is missing — it is just spread out. Kilometre data in GPS, cargo weight on the waybill, fuel on the fuel card statement. ISO 14083 requires them to be linked systematically.
A TMS is the natural place to bring all of this together, because route, cargo and vehicle are already in the system.
Why is ISO 14083 important for your business?
CSRD requires it. The EU's sustainability directive obliges large companies to document CO2 emissions from scope 3 — including purchased transport. Your customers need your CO2 data for their reporting. If you can't deliver ISO 14083-compatible figures, you are a challenge for them — not a solution.
Customers are making demands. Retail chains, manufacturers and logistics companies are increasingly requesting CO2 documentation as a supplier requirement. If you can deliver it — you are an attractive choice. If you can't, you risk losing the contract.
It is a competitive parameter. Companies that actively work with CO2 reduction use ISO 14083 data as documentation of their progress. This provides credibility and strengthens the relationship with customers who prioritise sustainability.
DORA and ISO 14083
DORA's CO2 module is built to comply with ISO 14083 automatically. You don't need to know the standard in detail — the system handles the calculation method for you.
For each order, DORA calculates CO2 emissions based on the route, vehicle, cargo weight and fuel type. Data is saved per order and can be aggregated per customer, route or period at any time.
With one click, you can generate a CO2 report for a specific customer for a given quarter — ready to send to their sustainability team or auditor. No manual calculations, no uncertainty about the method.
ISO 14083 is not just compliance — it is documentation that you take responsibility. It is a competitive parameter in a market that demands credible data.
Frequently asked questions about ISO 14083 and CO2 calculation
Does ISO 14083 replace EN 16258?
Yes. ISO 14083 from 2023 replaces EN 16258. It is more comprehensive, covers all modes of transport and is recognised globally. If you are still using EN 16258, you should update to ISO 14083 to ensure compliance with current requirements.
Do I need to collect data for ISO 14083 myself?
Not with DORA. All relevant data — routes, vehicles, cargo weight and fuel type — is already in the system as part of daily order management. DORA calculates CO2 automatically without extra work from your side.
Can I use DORA data in CSRD reporting?
Yes. DORA's CO2 calculations are based on ISO 14083, which is the recognised method for transport in a CSRD context. Data can be exported and used directly — by you or your customers' auditors. We always recommend coordinating with your auditor about the specific reporting.
