How do I calculate Scope 1 emissions for AASB S2 reporting via API?
The API returns fuel specific emission factors by state, which can be applied directly to fuel consumption figures to produce a Scope 1 estimate with a citable source.
What are National Greenhouse Account factors and where do I get them?
They're the official emission factors published annually by DCCEEW for estimating greenhouse gas emissions across fuel types, electricity, and other categories. Normally distributed as a workbook, available here as a structured API.
How do I use NGA emission factors in an automated carbon accounting workflow?
Factors can be queried by state, fuel type, and year, returning a structured value that plugs directly into an existing calculation pipeline rather than a manual spreadsheet lookup.
Which emission factor should I use for electricity consumption in each Australian state?
Electricity emission factors vary meaningfully by state, since each state's grid has a different generation mix. The API returns the factor for the specific state queried, rather than a national average.
How often do NGA factors update and how do I stay current?
DCCEEW publishes a revised workbook annually. The API reflects the current published version, with the version and publication year returned on every response.
How do I build AASB S2 climate disclosure reporting into my financial systems?
Emission factor retrieval with a citable version reference is one input into that reporting process, designed to sit alongside the financial systems producing the rest of the disclosure.
What is the difference between Scope 1, Scope 2, and Scope 3 under AASB S2?
Scope 1 is direct combustion, Scope 2 is purchased electricity, Scope 3 covers indirect emissions such as fuel extraction and transport. All three have distinct factors returned by the API where applicable.
How do I prove the emission factor version used in a historical climate report?
Every response carries the factor version and publication year at the time it was returned, which is the record needed to reconstruct what was used for a past calculation.
Which Australian companies are required to report under AASB S2 and by when?
Reporting phases in by company size and NGER status, Group 1 from January 2025, Group 2 from July 2026, Group 3 from July 2027. Full thresholds are covered in a separate post on who must report.
How do I integrate Australian NGA emission factors into an ESG data pipeline?
The API returns structured, versioned factor data that can be pulled into an existing pipeline the same way any other structured data source would be, without a manual workbook step in the middle.
