Scope 3 Supplier Emissions Data Response Support

That's very common. We help you work with what you have, bills, receipts, records, and use recognised estimation methods where exact data isn't available. Honest, well-documented estimates are far better than no response.

Yes, once we've built your emission profile, the core data can be adapted to different questionnaire formats. You won't need to start from scratch each time.

Large companies are increasingly required to report Scope 3 emissions under frameworks like AASB S2, ASIC guidelines, and the GHG Protocol. Your data feeds into their value chain emissions reporting. This is especially common in mining supply chains across the Bowen Basin, Pilbara, and Hunter Valley, and in Queensland government procurement where Scope 3 requirements now appear in contract pre-qualification. Many businesses have their registered office in Brisbane or Perth but their operations and Scope 3 exposure are concentrated in regional areas.

Most supplier questionnaires ask for summary figures: total Scope 1 and Scope 2 emissions in tCO₂-e, the methodology used, and any reduction targets. Full inventory disclosure is rare. The risk is sharing too little (looks evasive) or too much (commercial information goes outside your control). Aethiro's response packages share what is asked for, in the format requested, and document the rest internally for audit.

Three main formats: a simple PDF or Word form sent by email, a portal upload (CDP, EcoVadis, SupplyShift, Avetta, ISN), or a custom Excel template specific to one client's reporting system. The underlying data requested is largely the same. The work is in mapping your inventory to each format consistently.

Outcomes vary by client. Common consequences include: lower preferred-supplier scoring, removal from approved supplier lists, replacement with a default industry-average emission factor (which usually overstates your real footprint), or deferral of contract renewals pending data. Tender evaluations increasingly score sustainability criteria explicitly, so a missing response can shift a contract decision toward a competitor who responded.
