ASRS Reporting When You're a Team of One

4 min read · Published August 2026

You're the only person doing sustainability at your company, with no team behind you. ASRS has landed, the deadline is real, and the request for another hire came back as "not this year." A team of one can still get through an AASB S2 disclosure. Most of the year goes on manual data work rather than the standard itself, along with the assumption that the only fix is more people you won't get.

What ASRS actually asks for

Australia's mandatory climate regime is ASRS, and AASB S2 is the standard you report against. It isn't one emissions number but four pillars: governance, strategy, risk management, and metrics and targets. That four-part list is where first-timers freeze, so take it in order rather than all at once. The metrics pillar, which is your Scope 1, 2 and 3 footprint, is the one the other three build on, so start with the number and then work out the governance, strategy and risk disclosures around what it tells you. Which ASRS group you're in sets your timing, and the plain-English breakdown is here if you're still placing yourself.

Where the reporting year goes

Multiplying a litre of diesel by a factor is arithmetic that a spreadsheet does in a cell. The months go somewhere else: getting a kilowatt-hour figure out of a scanned electricity bill whose layout changed last quarter, reconciling a general ledger line against a supplier invoice, tracking down the fuel dockets that live in someone's ute. For a team of one, that is most of the job, and it is slow and repetitive. You came in to drive strategy and change, not to spend months on data entry.

Separate the repetitive work from the judgement

The most useful move for a team of one is to split the year's work in two. One half is repetitive and mechanical: pulling figures out of bills and invoices, reconciling them, and matching each line to an emission factor. The other half needs a person: deciding what's material, writing the strategy and risk narrative, and checking the numbers before they go out. Most of the hours go into the first half, so that's the part worth removing first. Whether you remove it by bringing in software is a separate question, and it depends on your volume and how much appetite you have to set a tool up. Knowing which half is which is the starting point for planning the year on your own.

Repetitive

The half that eats the year

Reading scanned bills and invoices, pulling figures out of the ledger, matching each line to the right NGA Factor, and running the Scope 1/2/3 calculations. Mechanical work, and most of the total hours.

Judgement

The half that needs you

Deciding materiality, framing the strategy and risk narrative, briefing the board, and reviewing the numbers before your name goes under them.

You stay the reviewer

If you do bring in software for the repetitive half, the thing to insist on is that you stay the reviewer. The disclosure carries your name, so every figure needs to trace back to its source document, the factor applied, and the reasoning behind how it matched. A total with no working behind it won't survive the moment an assurer asks how you arrived at it. Whatever tool you use, that traceability is the line to hold.

A plan a team of one can run

This reporting cycle

  • Place yourself: confirm your ASRS group and the deadline that sets your phasing.
  • Gather the raw material you already have (utility bills, fuel records, ledger, top suppliers) before touching the standard.
  • Get the footprint built: documents read, current factors applied, Scope 1/2/3 calculated, source trail intact.
  • Sequence the other three pillars (governance, strategy and risk) off the numbers, one at a time.
  • Review rather than re-key: your hours go to judgement and the board narrative, not data entry.

The manual data work is what a team of one can hand off. The judgement stays with you.

What to hand off, what to keep

If you're weighing whether to bring this in-house, hire a consultant, or use software, the trade-offs are in consultant vs software and how to choose, ASRS-ready. Whatever you look at, ours included, test it against your own data before you commit.

Frequently asked questions

Can one person do ASRS reporting without a sustainability team?+

Yes, but not by doing every task by hand. AASB S2 spans four pillars, and the metrics pillar alone can absorb months if you're keying data from bills and invoices. A team of one gets through it by sequencing the four pillars across the cycle and offloading the repetitive data work (document extraction, factor matching, calculation) so their own time goes to the judgement calls a person has to make.

Where do I even start with ASRS if I've never done it?+

Start with what you already have, not with the standard. Pull together your utility bills, fuel records, general ledger and major supplier invoices. That's the raw material for Scope 1 and 2 and the start of Scope 3. Get those into a system that reads them and calculates against current factors, then use that footprint as the basis for the governance, strategy and risk disclosures. Working backwards from the standard is where first-timers stall; starting from the documents you already have keeps things moving.

Do I need to hire someone to meet ASRS?+

Often not. Most of what you would hire someone to do is the manual workload, and that workload is the part that automates best. Before you fight for a hire you may not get, work out how much of the year is data entry and reconciliation versus genuine analysis. If it's mostly the former, offloading it gets you further, and it arrives this cycle rather than after a six-month recruit.

What is AASB S2 versus ASRS?+

ASRS is Australia's mandatory climate-reporting regime. AASB S2 is the standard you report against under it. Which ASRS group you fall into sets your timing and phasing. For a team of one, the practical read is that AASB S2 defines four disclosure pillars, and your job is to satisfy all four with evidence an assurer can test, not to become a full-time expert in the standard.
