About Acumentis ESG

Practical Sustainability & Climate Advisory

Making ESG Practical, Achievable & Impactful

Acumentis ESG is a national ESG consulting firm. We're the sustainability and climate advisory arm of the Acumentis Group, Australia’s only independent ASX-listed valuation and advisory business. We bring together technical depth and business realism to help you move from uncertainty to action. Our focus is on simplicity and building your internal skills so the results stick.

As a listed entity, Acumentis prepares its own climate disclosures using the same frameworks and technology we provide to you. This firsthand experience gives us a dual perspective. We've evaluated and refined the best reporting practices in real-world conditions. The result is an advisory offering grounded in experience. We're focused on what actually works to deliver defensible, decision-ready outcomes.

Our Philosophy: Preparation Over Perfection

ESG isn’t one-size-fits-all. We meet you where you are. You might be just beginning your journey or preparing for new mandatory climate reporting rules. Our sustainable development consulting approach ensures you lead with confidence. We help you learn as you go and embed lasting change for your business and the planet.

We help organisations:

  • Act with confidence
  • Learn as they go
  • Embed lasting positive change, for business and the planet

Our Approach to ESG & Sustainability

We make sustainability simple and commercially valuable. Our goal is to build your internal skills so you can operate independently without long-term consultant dependence.

  • Teach then handover: We train your people and provide the playbooks you need to run everything without us.
  • Scale team and technology: We provide flexible access to expert ESG consultants and integrated tools that scale with your needs.
  • Unlock commercial value: We turn climate work into a strategic advantage. This means stronger bids, cost savings, and better access to capital.
