Carbon assessment, evidence-first

Proof of your emissions. On demand.

A Scope 1 + 2 emissions assessment and Supplier Emissions Certificate, calculated under the Greenhouse Gas Protocol and recognised under AASB S2. AI-built, human-reviewed, delivered in 7 business days. Built for Australian SMEs that need to keep big customers, and for reporting entities that need real supplier data at scale.

Why this matters now

The pressure is landing in inboxes, not in policy papers.

Three things changed in the last six months. Together they explain why a supplier email arrived this week, and why the response window is shorter than most SMEs realise.

01

This is a three-year wave, and it has already started.

Under AASB S2, Group 1 entities have reporting periods from 1 January 2025, Group 2 from 1 July 2026 and Group 3 from 1 July 2027. Scope 3 is the emissions of their supply chain, which means yours. The only question is which group's deadline catches you.

02

Roughly 80% of supply-chain emissions sit with SME suppliers.

Reporting entities can't hit their Scope 3 numbers without supplier data. Procurement teams have started sending the email. The cleanest path back is a recognised Supplier Emissions Certificate.

03

No certificate, no panel. It's credentials, not consent.

Tender shortlists, panel renewals and procurement reviews now ask for emissions data alongside insurance and safety. It's like a union site: no ticket, no work. "We're working on it" is no longer an answer.

Proof, on demand

A document your customer's auditor will actually accept.

Less Carbon's output isn't a pretty PDF with a logo on it. It's a Scope 1 + 2 statement built on real methodology, with the workings visible. Three things make it stick.

Built on govt and industry standards

We base our reporting on government and industry standards, in standardised formats your clients will accept and appreciate. Exactly what they need. Read the methodology.

Recognised under AASB S2

Your certificate is calculated under the Greenhouse Gas Protocol, the measurement approach recognised under AASB S2, and built to feed the Scope 3 disclosure your customer needs. The credential they're asking for, in the form they expect.

Human QA on every certificate

AI runs the calculation. A real expert reviews and signs off before the certificate goes out. No "AI told us so" if it's ever questioned.

Trust signals at launch

Less Carbon is new. The experience behind it is not.

The reporting regime is new, but the principles are not: clear records, defensible methodology, structured evidence and documents that customers, tender panels, lenders and reporting entities can actually review and use. Built by Australian professionals with 50+ years of combined experience across compliance, regulated industries, finance and procurement. Review our methodology and a sample certificate before you pay.

Why Less Carbon exists

Built from inside the problem, for the people now being asked.

Across compliance and heavily regulated Australian industries, we kept seeing the same gap: capable businesses asked for emissions data, with no simple, standard way to produce it. The market needed a real document, fast, at a fair price. So we built one.

Less Carbon brings 50+ years of combined experience across compliance and heavily regulated Australian industries, on both sides of the supplier-data conversation. We've seen the spreadsheets that get rejected, the audit notes that flag "data quality limitations" and the procurement reviews that quietly shortlist someone else. Less Carbon was built to make that whole conversation easier for the supplier, and faster for the reporting entity.
