Tool · Haulage emissions

Haulage emissions, with the assumptions on the page.

Most freight calculators hand you a tonne-kilometre factor and hide what produced it. This one derives the factor from fuel burn and payload you can see and change.

Why this works differently. NGA publishes transport factors per litre of fuel, not per tonne-kilometre. Any t-km figure is a derivation, so this tool shows the derivation instead of asserting a result. The only value taken from the source is the diesel factor.

Diesel factor: 2.71 kg CO2-e per litre, attributed to DCCEEW National Greenhouse Accounts Factors 2025, retrieved 2026-08-19. Fuel burn and payload are your inputs, not published values.
NGA Factors must not be used to meet reporting requirements under the National Greenhouse and Energy Reporting Act 2007. Figures here are indicative estimates for planning and tender narrative, not a compliance calculation.

Why the factor is the argument

Published tonne-kilometre factors vary by more than a third depending on what sits behind them. GLEC Framework v3.2, Table 8 puts a Articulated 34-40t GVW, average/mixed, 60% load, 17% empty, diesel at 0.101 kg CO2-e per tonne-km on a well-to-wheel, AR6 GWP-100 basis. A laden, combustion-only figure for the same truck lands nearer 0.07. Neither is wrong. They answer different questions.

The difference is made up of three things: whether fuel production and delivery are counted, whether the empty return leg is counted, and what payload the truck is assumed to be carrying. A calculator that hides all three is not giving you a number you can defend.

What to expect from an assessor. The question is rarely whether the factor is right. It is whether you can say where it came from, what load it assumes, and whether the return leg is in or out. Those three answers are the difference between an estimate and an exhibit.

Where haulage meets the tender

Queensland Procurement Policy 2026 scores local benefit as a purposeful procurement outcome under Rule 20, weighted between 10 and 20 per cent of the evaluation. Proximity to disposal or supply is a genuine commercial and emissions argument, but it is no longer assessed against the 125km threshold used by the former Local Benefits Test, which was replaced in January 2026.

The Waste to Resource schedule (C7810.S12.TIC) requires tenderers to nominate recycled material percentages or justify not maximising diversion. Diversion reduces both haulage emissions and levy exposure, which makes it one of the few moves that scores twice.

Levy and emissions move together. Shortening a haul cuts fuel and cuts nothing off the levy, because the levy rate is set by where the waste was generated, not where it goes. Work the levy separately in the waste levy calculator.

AASB S2 and where this sits

Australian sustainability reporting standards phase in by entity size, and Scope 3 disclosure is where most construction businesses first meet a number they cannot produce from their own records. Contracted haulage is a common first line item, because it is measurable, material, and sits in someone else's fleet.

This tool produces a planning estimate with a stated method. It is not a reporting calculation, and NGA itself is explicit that its factors are not to be used for NGER Act reporting. For a disclosure that has to survive assurance, the derivation matters more than the decimal places.

Before the number goes in a submission

What an assessor will ask
Source named: the fuel factor is attributed to a dated published edition.
Payload stated: the assumed load per trip is written down, not implied.
Return leg declared: empty running is either counted or explicitly excluded.
Boundary declared: tank-to-wheel or well-to-wheel, said once and kept consistent.
Not presented as compliance: described as an indicative estimate, not an NGER figure.
