Emissions calculator

The results generated by Aurizon’s greenhouse gas (GHG) emissions calculator are intended for general informational purposes only. Aurizon cannot ensure the accuracy and comprehensiveness of a customer's resulting GHG emissions and net savings from its supply chain activities as calculated by this tool. Actual GHG emissions related to a specific rail freight service may vary due to factors including (without limitation) locomotive type, quantity, and other variables inherent to the rail network, commodity type, and route. Users are advised to interpret the calculator results with caution and to consider additional factors that may impact GHG emissions and net savings in their specific context.

The GHG emissions output from this calculator should not be relied upon for Users' own reporting purposes and Aurizon bears no responsibility for use of outputs from this calculator in Users' own reporting.

The GHG emissions factors utilised for rail and road supply chain activities are sourced from the most current version of the Australian Government Department of Environment and Energy National Greenhouse Accounts Factors and the road haulage calculations utilise the Australian Trucking Association Truck Impact Chart: Technical Advisory Procedure. These resources are publicly available for reference and may be the subject of updates from time to time, in which case the GHG emissions calculator may not accurately reflect a customer's resulting GHG emissions and net savings from its supply chain activities.

Distances for key Aurizon haulage routes are approximate, and distances for trucking and railing routes may vary even if the origin and destination are the same or similar.

In this calculator:

• "tonnes (payload)" refers to the total tonnage (payload) of the commodity to be hauled, measured in metric tonnes.
• "distance" denotes the one-way haulage distance from origin to destination, measured in kilometres.
• "emissions" specifically pertains to those resulting from the combustion of mineral diesel in road and rail operations.
