The green freight tender question procurement hasn't been asking

Two problems with a “20% reduction” claim

When a carrier offers a green freight surcharge on a lane and claims it will reduce your CO₂ emissions by 20%, the natural procurement response is to ask: 20% of what? There are two distinct problems with that figure that are easily conflated but require different responses.

The first is methodological inconsistency across carriers. The same physical solution – say, an HVO30 blend on a Hamburg–Milan lane – can produce a 20% or a 22% reduction figure depending on which emission factors a carrier applies, which methodology is used, and how data is derived and cleaned. Because carriers do not consistently disclose the underlying methodology, their percentages cannot be directly compared. The only way to generate a comparable evaluation is to recalculate all options using the same consistent methodology, baseline, and consistent emission factors (unless they are provided as primary data in tender discussions).

The second problem is baseline choice: diesel reference versus current lane. Both perspectives are analytically valid, but they answer different questions:

• Comparing a green solution against a diesel baseline allows you to calculate € / tCO₂e reduced on a comparable basis across different carriers and solutions. This is the commercial metric.

• Comparing against your current lane operationalization reveals the effective additional reduction relative to what is already running – the contribution toward your actual Scope 3 targets. If your Hamburg–Milan carrier is already operating on HVO30, an HVO30 offer from a competitor delivers zero additional reduction versus your status quo, regardless of how the percentage is framed against diesel.

Procurement teams that cannot distinguish between these two baseline perspectives or that accept a carrier percentage without recalculating consistent assumptions are not comparing offers. They are comparing marketing.

Four steps to a procurement-ready evaluation

Working through a green freight offer rigorously requires four sequential steps that procurement, not the sustainability function, needs to own.

1. Translate the percentage into absolute terms. Convert the claimed reduction to tCO₂e using consistent, methodology-aligned default assumptions – or, where carriers provide primary data, against those specifics. ISO 14083 and the GLEC Framework provide a common basis. Without this step, offers that use different baselines or different fuel emission factors cannot be meaningfully compared.

2. Recalculate all options on consistent assumptions. Do not rely on each carrier’s published reduction figures. Apply the same baseline emission factors to all offers on this lane. This is what produces a genuinely comparable evaluation, independent of how each carrier has framed their methodology.

3. Derive the cost per tonne of CO₂ reduced. The green premium on a freight offer is only a meaningful procurement metric when expressed as € per tCO₂e reduced. This number serves two purposes: it enables direct comparison across competing offers on the same lane, and it can be benchmarked against the internal carbon reduction price threshold that sustainability governance has set. Without it, procurement cannot have a principled conversation with budget holders about whether a premium is justified.

4. Measure the actual delta from your current operationalization. Once you have the diesel-baseline metric, calculate what the proposed solution buys you for an additional Scope 3 reduction relative to what is running today. This is the number that tells you whether you are making real progress toward your decarbonization targets – or paying a premium for a solution that replicates something you already have.

A procurement capability, not a sustainability task

The data infrastructure required to run these four steps sits at the intersection of emissions calculation, lane-level analysis, and commercial modelling. It is not a post-hoc reporting function. It is a pre-signature evaluation capability, and the tender is the moment when it needs to be established

Procurement teams that identify emission hotspots at tradelane level before entering a tender cycle are in a fundamentally different position from those who receive a carrier's green claim cold. They can model the Scope 3 impact of different decisions against their decarbonization roadmap targets before committing budget. They can challenge a green premium with a number, not a sentiment.

As green freight products become more common in commercial tender packages, this capability gap will widen. Carriers and forwarders who have invested in verified, methodology-compliant emissions data will present increasingly sophisticated offers. The procurement teams that can meet that sophistication with independent, lane-level analysis will negotiate from a position of evidence. Those that cannot will pay for the story.
