Calculate Scope 1 stationary-energy fuel combustion with National Greenhouse Accounts factors, alongside dual-method Scope 2 — with versioned factor stamps and a combined-scope disclosure built for AASB S2 reporting.
Under AASB S2 / ASRS, mandatory climate disclosure requires both Scope 1 and Scope 2 greenhouse gas emissions from the first reporting year. For most commercial and industrial organisations, Scope 1 is dominated by stationary-energy fuel combustion — the natural gas, diesel and LPG burned in boilers, furnaces and on-site generation.
gridIQ calculates that Scope 1 figure from your fuel quantities using the National Greenhouse Accounts (NGA) factors, and presents it alongside the dual-method Scope 2 engine that already powers gridIQ's electricity emissions reporting. The result is a combined Scope 1 + 2 position with the factor traceability an assurance provider expects.
Scope 2 is the harder half of the problem in Australia's volatile grid — see the ASRS Scope 2 reporting page for the dual-method Scope 2 methodology that pairs with your Scope 1 figure.
Enter fuel quantities — natural gas, diesel, LPG, fuel oil and more — and gridIQ applies the National Greenhouse Accounts (NGA) factors for stationary-energy fuel combustion to produce your Scope 1 figure.
Scope 1 stationary energy sits alongside dual-method Scope 2 (time-matched location-based and instrument-based market-based) so you see your combined electricity-and-fuel emissions position in one place.
Every fuel line is itemised with its energy content and emission factor, so the Scope 1 total can be traced back to each input rather than landing as a single opaque number.
Each calculation records the NGA factor edition used (e.g. NGA 2024), so an auditor can reconcile any figure against the published DCCEEW workbook without spreadsheet archaeology.
When a disclosure is created with Scope 1 fuels, the disclosure document renders combined Scope 1 + 2 — the audit-ready artifact AASB S2 reporters need from FY2024-25 onwards.
The Scope 1 calculator and combined-scope disclosure are part of Pro ($499/mo, $399/mo billed annually), alongside the full Scope 2 engine, compliance calendar and Watt AI.
The combined Scope 1 (NGA-aligned) + dual-method Scope 2 calculator and the combined-scope ASRS disclosure are included with Pro ($499/mo, $399/mo billed annually). New accounts start with a 21-day Pro trial, no card required.
