CO₂ reporting

Connect freight emissions to the flows you can act on.

Bring shipment data together to understand its contribution to emissions. Share a common view of scope, estimates and options to examine with transport and sustainability teams.

In practice

Understand what the total represents

A transport emissions inventory should show which operations are included and which data was used. Without that context, a total can change because activity has shifted, new flows have been included or information has become more complete.

OneChain connects emissions reporting to transport data to give supply chain and sustainability teams a shared basis for analysis. Scope and available information inform the interpretation of emissions instead of remaining in a separate consolidation file.

A practical case · Illustrative example

Urgent departures on the same lane

The team wants to examine this flow’s contribution to transport emissions.

Scope
Selected lane and period
Data
Modes, routes and shipment characteristics
To complete
Missing weight on one shipment
The decision to prepare

Establish a reliable comparison and examine whether earlier planning could enable a different arrangement.

Find the flows contributing to the result

Mode, route and shipment characteristics are among the inputs useful for calculation. OneChain uses EcoTransIT to estimate transport emissions. The calculation scope and data used are specified for your project.

References and shipment coverage form the basis of comparison. Missing data should remain identifiable so it is not confused with zero emissions. Teams can understand what contributes to the result and what still needs completing.

Prepare a discussion about cost, time and impact

On a lane with frequent urgent departures, the team examines the operations, their modes and their contribution to the inventory. The question becomes practical: could earlier planning allow a different arrangement for some departures?

Reporting prepares that discussion with purchasing, procurement and transport. Availability, lead-time and service constraints remain essential when deciding whether an option can be implemented.

Measure changes on a comparable basis

To track an action, maintain a consistent view of flows, periods and assumptions. A lower total may simply reflect fewer shipments. The team should distinguish activity from the intended effect and retain visibility of estimated or missing data.

Coverage changes also belong in the analysis. Adding flows or completing a period’s data changes the interpretation of the inventory. Documenting these developments helps teams read the result together.

Prepare your implementation

Details to work through using your flows and organization.

Which data should we prepare?

Shipment references, modes, routes and characteristics useful for calculation. The project specifies required fields and how missing information is handled.

How should the reporting scope be defined?

List the flows and periods concerned, then the transport stages covered. Retain this definition to interpret changes and compare results over time.

How should transport work with sustainability teams?

Share calculation scope, data and assumptions. Transport teams provide operational context; sustainability teams contribute to interpreting the inventory and tracking selected actions.
