About Carbonhalo
Built to close the Assurance Gap.
AASB S2 demands audit-ready climate disclosure. Auditor independence can limit how assurance firms help you prepare it. Carbonhalo bridges the gap with trusted, evidence-backed disclosures ready for assurance.

Independent by design
Designed to work with your auditor.
Carbonhalo prepares your AASB S2 climate reporting with the assurance process in mind from the start, giving your assurance provider clear, traceable supporting evidence to review. The roles are clear, separate and designed to work together.
- Your assurance provider remains independent: we prepare the reporting; they provide the assurance.
- Built with assurance in mind: our calculations, evidence and workpapers are structured for efficient reviews.
- A clear audit trail: data, assumptions, calculations and supporting documentation are traceable.
- No need to change assurance providers: Carbonhalo works alongside your existing auditor or assurance provider.
“We are highly complimentary of the quality, completeness and professionalism of Carbonhalo’s climate reporting work. The standard of the documentation significantly assists the audit process.”
“We have greatly valued our partnership with Carbon Halo and the reliable service and trusted advice they consistently provide. Their team has developed a strong understanding of our business, tailoring their guidance to what works best for our organisation and supporting both our sustainability planning and reporting objectives. Carbon Halo engages effectively with our people, building positive working relationships across the business and making complex sustainability requirements easier to navigate. Their expertise, responsiveness, and practical approach have been instrumental in helping us meet our reporting obligations and continue progressing our sustainability goals with confidence.”

Valued by clients
What working with us is like.
Auditors value the documentation. Clients value the partnership: advice tailored to the business, people who are easy to work with, and reporting obligations met with confidence.
What you told us
You need to get this done as easily, affordably and confidently as possible.
We spent months talking to CFOs and finance teams facing their first mandatory climate report. The message was consistent: you don’t need another system to manage, another team to build or a long consulting engagement to navigate.
You need a practical, cost-effective way to get your AASB S2 disclosure done properly, with the right evidence behind it and minimal impact on your team.
So that’s what we built.

Who is behind it
Three directors. A lifetime of experience.
Carbonhalo is led by directors who have run large ASX 200 companies, consulted to some of Australia’s biggest businesses, and founded technology companies.
Director
Ben co-founded Carbonhalo after a career running operations at scale as Chief Operating Officer of Tassal, Australia’s largest salmon producer. He brings the strategic lens from a board perspective and works directly with client boards and audit teams on the governance and risk-management of climate disclosures.
Director
Richie co-founded Carbonhalo and sits on the board of Siecap, a supply chain and project management consulting business. As a qualified carbon accountant he built Carbonhalo’s product & technology and works with the audit profession on structuring raw operational and financial data into mapped, auditable evidence.
Ian Warner
Director
Ian founded and built ISW, an IBM Platinum Partner, delivering enterprise technology and data platforms to large Australian organisations. That background sits behind how Carbonhalo handles client data at scale.
A team built around the work
Behind every Carbonhalo engagement is a multidisciplinary team of carbon accountants, data analysts, management consultants and technology specialists, supported by technology that helps us process, check and manage the work at scale.
Different expertise, working together through one process, so you get the capability of a much larger function without having to build one.
Who we work with
Built with the firms that ultimately assure your reporting.
Carbonhalo works closely with leading Big 4 and mid-tier accounting and assurance firms to make sure our reporting, evidence and workpapers are practical to review and ready for independent assurance.
We understand what assurance teams need to see: clear data, traceable calculations, documented assumptions and a defensible audit trail; and we build that into the process from the start.
The result: reporting that is easier for your assurance provider to understand, test and rely on.

Capacity
We have capacity to support businesses preparing for upcoming legislative reporting requirements; however, organisations that plan early will be best positioned to secure their preferred delivery window and achieve a considered, high-quality outcome. As reporting deadlines approach, demand for specialist support increases and provider availability becomes more limited.
