Reducing freight emissions starts with understanding their sources. An annual total alone does not show where to act or which constraints explain transport choices.

## Establish a comparison basis

Define included shipments, journey legs, modes and period. Gather weights, distances and inputs required by the method. Separate measured data, estimates and missing information.

Results also depend on boundaries: emissions during use or across the energy cycle, expressed as CO₂e. [Smart Freight Centre’s GLEC Framework](https://smartfreightcentre.org/news/13311209) explains these distinctions. Retain the version and factors used when interpreting changes over time.

## Choose actions around your flows

- **Address recurring emergencies**: investigate late departures and improve supplier-readiness planning.
- **Consolidate where appropriate**: bring volumes, destinations and dates together to assess better loading.
- **Consider another mode**: compare the full journey, lead time, handling stages and product constraints.
- **Assess energy options**: ask providers for the method and evidence behind their offers, using a life-cycle perspective.

No fuel or modal change delivers the same benefit on every route. Decisions also need to consider service, cost and inventory effects.

## Follow the result

Choose a flow, an owner and a baseline period. Compare total emissions and a relevant intensity, such as per tonne-kilometre, explaining changes in volumes and methodology.

[OneChain CO₂ reporting](https://onechain-tms.com/en/co2-reporting) helps connect emissions to operations. It supports analysis; an actual reduction requires an observed change and a substantiated comparison.
