Something has changed in regional Queensland. Businesses that have spent years operating without any thought of carbon reporting are now finding Scope 3 questionnaires in their email inboxes, attached to contract renewals, pre-qualification applications, and supplier registration forms. If this has happened to you, you're not alone, and the reason isn't random. It's systemic.
What Scope 3 actually means, and why it affects you
Scope 3 emissions are the greenhouse gas emissions that occur in a company's value chain, before and after their own operations. When BHP mines coal, their Scope 1 emissions include the diesel their equipment burns. But their Scope 3 includes the emissions generated by every contractor, supplier, and service provider that supports that operation. That includes your earthmoving company, your transport business, your catering supplier, and your maintenance contractor.
When a major company commits to cutting their Scope 3 emissions, as BHP, Rio Tinto, Glencore, Coles, Woolworths, and dozens of ASX-listed companies have, the practical consequence is that they need to know what each supplier's emissions are. That requirement flows down the supply chain, and it reaches regional Queensland businesses directly.
Who is asking for Scope 3 data in Queensland?
The pressure is coming from several directions simultaneously:
- Mining and resources majors: Companies operating in the Bowen Basin, Mount Isa, North Queensland, and Central Queensland are applying supplier sustainability requirements to their Tier 1 and, increasingly, Tier 2 contractors. If you supply services or materials to a major mining operation in Queensland, this is likely already reaching you.
- Queensland Government: The state government's updated procurement policy includes sustainability criteria for larger contracts. Businesses in Brisbane and regional Queensland tendering for government infrastructure, services, and supply contracts are encountering carbon questions in tender documents.
- Food and retail supply chains: Coles and Woolworths are actively building Scope 3 data from their supplier base. Queensland agribusinesses, beef producers, sugar mills, grain growers, are increasingly part of this data collection.
- Major construction and infrastructure projects: Brisbane's construction boom and major regional infrastructure projects are drawing in Scope 3 requirements through the project's head contractor and developer commitments.
Brisbane businesses and the Scope 3 chain
It's easy to assume Scope 3 pressure is purely a regional and resources issue, but Brisbane-based businesses are equally caught. Brisbane head offices that supply services into regional operations, Brisbane construction companies working on government infrastructure, and Brisbane logistics and transport businesses operating statewide are all facing the same data requests. The questionnaire might land at the Brisbane office, even when the operations generating the emissions are in Rockhampton or Mackay.
💡 "You don't have to be a large company to receive a Scope 3 questionnaire. You just have to supply to one."
What you're actually being asked to provide
Scope 3 questionnaires vary in complexity, but the most common requests from Queensland mining and government clients are:
- Your total Scope 1 and Scope 2 emissions for the past financial year (in tCO₂e)
- The emission factors and methodology you used
- Whether your data has been independently verified
- What emission reduction targets or initiatives you have in place
- In some cases, your Scope 3 emissions from specific upstream or downstream activities
Most SMEs can answer the first three questions with a well-prepared carbon footprint. The fourth requires a reduction plan. Very few regional SMEs are being asked for detailed Scope 3 data at this stage, that tends to come later, as the framework matures.
How to respond without a sustainability team
The good news is that responding to a Scope 3 questionnaire doesn't require a dedicated sustainability team or expensive software. For most regional Queensland and Brisbane SMEs, the data you need already exists, in your fuel records, electricity bills, and vehicle logs. The work is in turning that data into a documented, formatted carbon footprint that matches what your client is asking for.
Our Supplier Data Response service is specifically designed for this situation, we work with what you have, prepare the data in the format your client expects, and document everything so you're not starting from scratch next time. If a tender is involved, a Tender-Ready Carbon Snapshot™ can get you the right numbers in 3–5 business days.
The worst response to a Scope 3 questionnaire is no response. Clients are generally understanding of businesses that are new to carbon reporting, what they don't accept is silence.
