The question keeps surfacing in boardrooms across Australia: "What does 'good' look like for ASRS implementation?" With the Australian Sustainability Reporting Standards (ASRS) now in effect and reporting already underway for Group 1 entities, finance leaders and sustainability professionals need more than vague compliance guidance. They need a practical, phased roadmap that transforms overwhelming regulatory demands into manageable implementation steps.
The challenge isn't just understanding what ASRS requires, it's building the systems, processes, and capabilities to deliver audit-ready disclosures consistently. Whether you're in Group 1 (already reporting), preparing for Group 2 (starting July 2026), or Group 3 (starting July 2027) implementation, this 24-month roadmap provides the structured approach that successful organisations are using to navigate from initial data collection through to comprehensive climate disclosure.
Your first priority is creating robust data collection systems that will support both current reporting needs and future regulatory expansion. This phase focuses on building the infrastructure that underpins everything else.
Month 1-2: System Integration and Data Mapping Begin by integrating your financial systems with carbon accounting platforms. Connect ERP systems, accounting software, and procurement platforms to enable automated data extraction. Map your existing data sources to identify gaps in Scope 1, 2, and 3 coverage.
Month 3-4: Baseline Measurement Establish your organisational carbon footprint across all three emissions scopes using spend-based calculations where necessary. This baseline becomes the foundation for all future reporting and target-setting activities. Focus on data quality over perfection, you can refine accuracy in subsequent phases.
Month 5-6: Governance Framework Development Create internal policies, procedures, and approval workflows that will satisfy audit requirements. Establish data ownership responsibilities across departments and implement version control systems for all climate-related data and calculations.
Team Structure and Training Identify key personnel across finance, operations, and sustainability functions who will own different aspects of ASRS implementation. Provide comprehensive training on carbon accounting principles, data collection methodologies, and audit preparation.
Stakeholder Alignment Secure executive sponsorship and board oversight for the ASRS implementation program. Establish clear communication channels between finance, sustainability, and legal teams to ensure coordinated preparation efforts.
Month 7-8: Scope 3 Enhancement Move beyond spend-based calculations by implementing supplier engagement programs. Deploy supplier portals for direct emissions data collection and establish partnerships with key suppliers to improve data accuracy across your value chain.
Month 9-10: Assurance Preparation Engage with external assurance providers to understand specific documentation requirements. Implement audit trail capabilities and begin quarterly internal reviews to identify and resolve data quality issues before external scrutiny.
Month 11-12: Technology Optimisation Refine your carbon accounting platform based on operational experience. Enhance automation capabilities, improve data visualisation, and ensure seamless integration between measurement, reporting, and strategic planning functions.
Target Setting and Planning Establish science-based emissions reduction targets aligned with your business strategy. Develop decarbonisation roadmaps that identify specific initiatives, timelines, and resource requirements for achieving these targets.
Financial Integration Begin incorporating climate risks and opportunities into mainstream financial planning processes. Develop carbon pricing scenarios and assess the financial implications of different decarbonisation pathways.

Month 13-14: Multi-Framework Alignment Ensure your systems can simultaneously support ASRS, CDP, TCFD, and other disclosure frameworks. Develop standardised data templates that eliminate the need for separate data collection processes across different reporting requirements.
Month 15-16: Narrative Development Create compelling sustainability stories that transform raw data into strategic business communications. Develop templates for investor presentations, board reports, and public disclosures that demonstrate clear links between climate action and business value.
Month 17-18: External Validation Conduct comprehensive third-party assurance of your climate data and disclosures. Use this process to identify and resolve any remaining data quality issues and strengthen internal controls.
Board and Executive Readiness Provide comprehensive climate literacy training for board members and executives. Ensure leadership can confidently discuss climate risks, opportunities, and strategic responses with investors and stakeholders.
Customer and Supplier Communication Develop customer-facing emissions reporting capabilities to support tender responses and supply chain requirements. Create supplier engagement programs that drive emissions reductions across your value chain and strengthen relationships with sustainability-focused clients.
Month 19-20: Full Disclosure Preparation Complete your first comprehensive ASRS-compliant climate disclosure. Conduct internal reviews and stakeholder feedback sessions to refine content and presentation before public release.
Month 21-22: Process Automation Implement advanced automation capabilities that reduce manual effort in data collection, calculation, and reporting processes. Establish quarterly reporting cycles that maintain data freshness and accuracy.
Month 23-24: Continuous Improvement Establish ongoing monitoring and improvement processes that ensure your climate disclosures evolve with changing regulatory requirements and stakeholder expectations.
Business Process Integration Fully integrate climate considerations into core business processes including strategic planning, capital allocation, risk management, and operational decision-making.
Performance Management Link climate performance to executive compensation and departmental KPIs. Establish accountability mechanisms that drive continuous improvement in emissions reduction and disclosure quality.
Choose platforms that can scale with your business and adapt to evolving regulatory requirements. Prioritise solutions that offer comprehensive audit trails, multi-framework support, and integration with existing business systems.
Engage qualified sustainability consultants who understand both technical accounting requirements and business strategy implications. This expertise is essential for navigating complex regulatory requirements while building genuine business value.
Successful ASRS implementation requires significant organisational change. Invest in comprehensive training programs, clear communication strategies, and ongoing support systems that help teams adapt to new processes and requirements.
Plan for substantial resource requirements across finance, sustainability, operations, and IT functions. Successful implementations typically require dedicated project management and cross-functional coordination over the full 24-month period.
Effective ASRS implementation delivers measurable benefits beyond regulatory compliance. Look for improvements in data accuracy, process efficiency, stakeholder engagement, and strategic decision-making capabilities.
Track key performance indicators including data collection timeframes, audit preparation efficiency, stakeholder satisfaction scores, and the integration of climate considerations into business planning processes.
The most successful ASRS implementations view compliance as the starting point for broader sustainability transformation. Organisations that excel use the 24-month implementation period to build competitive advantages through improved operational efficiency, enhanced stakeholder relationships, and strengthened strategic positioning.
By following this structured approach, your organisation can transform ASRS compliance from a regulatory burden into a strategic asset that drives sustainable business growth. The key is treating implementation as a comprehensive business transformation program rather than a narrow compliance exercise.
Start early, invest appropriately, and maintain focus on building capabilities that deliver value well beyond the initial compliance deadline. With proper planning and execution, your 24-month ASRS journey becomes the foundation for decades of sustainable business success.
