ESG Strategy Launches Fractional Chief Sustainability Officer Service for Australian Mid-Market Companies

SYDNEY, AUSTRALIA - [7 January 2026] - ESG Strategy, a leading Australian sustainability consultancy, today announced the launch of its Fractional Chief Sustainability Officer (fCSO) service a first-of-its-kind solution tailored for mid-market Australian businesses with revenues between $20 million and $500 million.

This timely launch addresses the urgent need for ASRS (Australian Sustainability Reporting Standards) compliance, as mandatory climate disclosures commence for Group 1 entities in January 2025 and for Group 2 in July 2026.

"Mid-market companies now face the same climate reporting requirements as the ASX200, but often lack the resources to hire a full-time sustainability executive," said Lee Stewart, Founder and Principal Consultant at ESG Strategy. "Our Fractional CSO model gives these businesses access to senior ESG leadership and board-ready expertise at a fraction of the cost."

Turning Compliance Into Competitive Advantage

ESG compliance is now mandatory. ESG Strategy's approach goes beyond risk mitigation—helping Australian mid-market businesses turn compliance into a true competitive advantage. By embedding with client teams, ESG Strategy delivers measurable business results, reduces compliance risk, and positions clients to win on tenders, reputation, and stakeholder trust.

The Fractional CSO Advantage

Unlike traditional consulting, ESG Strategy's fCSO service embeds directly with client teams, building internal capability and ensuring sustainability is integrated into business strategy and operations. Key features include:

ASRS Compliance: Scope 1, 2, and 3 emissions reporting; climate risk assessment
Board Governance: ESG strategy development; board-ready reporting frameworks
Operational Integration: Embedding sustainability across business functions
Stakeholder Engagement: Investor relations, customer ESG requirements, supply chain compliance
