What Is ESG Reporting Software?
Core Functions
ESG reporting software platforms automate and streamline the ESG data collection, management, calculation, and reporting process. Key functions include:
- Data collection: Centralised platform for departments to submit ESG metrics and supporting documentation
- Data management: Version control, audit trails, data storage, security
- Calculation and conversion: Automated emissions calculations, unit conversions, aggregation of data from multiple sources
- Reporting: Automated report generation, mapping to frameworks (AASB S1/S2, GRI, TCFD, CDP), export in multiple formats
- Workflow management: Approval workflows, sign-offs, escalation of data quality issues
- Historical tracking: Maintain and compare multi-year data, identify trends
Types of ESG Reporting Software
Standalone ESG Platforms
Characteristics: Purpose-built ESG data collection and reporting platforms
Advantages:
- Specialised features for ESG data (emissions calculations, materiality frameworks)
- Flexibility to customise to your processes
- Support for multiple reporting frameworks (AASB, GRI, TCFD, CDP)
Disadvantages:
- May require manual integration with financial systems
- Standalone cost, not bundled with other business tools
- Implementation can be complex
Enterprise Software with ESG Modules
Characteristics: Large ERP systems (SAP, Oracle, Microsoft Dynamics) increasingly include ESG/sustainability modules
Advantages:
- Integration with existing financial and operational data (energy, HR, procurement)
- Unified data governance across financial and ESG
- Scalability for large, complex organisations
Disadvantages:
- Implementation can be expensive and time-consuming
- ESG modules may not have the depth of specialist platforms
- Configuration requires significant ERP expertise
Spreadsheet-Based Systems
Characteristics: Excel or Google Sheets used to collect and manage ESG data
Advantages:
- Low cost
- Familiar to most users
- Quick to set up
Disadvantages:
- Significant error risk (formula errors, version confusion)
- Limited audit trail and version control
- Poor scalability for complex data or large organisations
- Difficult to implement approval workflows and data validation
- For AASB S1 compliance, assurance providers view spreadsheet systems as high-risk
Recommendation: While spreadsheet-based systems are suitable for early-stage ESG reporting or smaller organisations, organisations subject to mandatory AASB S1/S2 reporting should invest in dedicated ESG software or enterprise ESG modules for better data governance and audit support.

Evaluating and Selecting ESG Reporting Software
Step 1: Define Requirements
Before evaluating vendors, clarify your needs:
- Data collection scope—which departments, how many facilities/sites?
- Geographic complexity—single country or multinational?
- Reporting frameworks—AASB S1/S2 mandatory; also GRI, TCFD, CDP?
- Integration requirements—will system need to pull data from existing systems?
- Number of users—how many people will access the platform?
- Support needs—do you need vendor support or can you manage internally?
- Budget and timeline—when do you need the system operational?
Step 2: Research Options
Research vendors through:
- Analyst reports (Gartner, Forrester on ESG software)—note these may focus on global market, not Australian-specific vendors
- Industry associations (AASB publishes resources on software compliance)
- Peer recommendations—ask similar companies what they use
- Case studies—request vendor case studies of Australian implementations
- Vendor comparison tools available online
Step 3: Request Demos and Proposals
For shortlisted vendors:
- Request product demonstration focused on your use case
- Ask about AASB S1/S2 compliance features and updates
- Request proposal including implementation timeline, training, support
- Get pricing (note: many ESG platforms are subscription-based with per-user costs)
- Request references from Australian customers
Step 4: Evaluate Against Criteria
Create evaluation scorecard ranking vendors on:
- AASB S1/S2 feature coverage
- Ease of use (important for broad adoption across organisation)
- Integration capabilities (with your existing systems)
- Reporting flexibility (can it output your desired report formats?)
- Vendor reputation and stability (will they be around in 5 years?)
- Cost (total cost of ownership including implementation, per-user fees, support)
- Support and training quality
Step 5: Negotiate Contract Terms
Key contract points:
- Data ownership—who owns your data if you leave vendor?
- Data export—can you easily export data in standard formats?
- Implementation SLA—what are promised timelines and support?
- Uptime/reliability guarantees
- Security and compliance (data encryption, backup, disaster recovery)
- Training and onboarding included in price?
- Support response times
- Price escalation clauses
Implementation Best Practices
Plan the Implementation
- Assign internal project lead and implementation team
- Develop detailed implementation plan with timeline (typically 8–16 weeks for deployment)
- Define data governance and system access policies before launch
- Plan training—ensure all users understand how to collect and submit data
Data Migration
- Map existing data to system fields
- Clean and validate historical data before migration
- Establish baseline year data in system
Testing and Validation
- Conduct pilot with select departments before full rollout
- Validate calculations (particularly emissions conversions)
- Test reporting outputs match expected formats
Training and Change Management
- Train data stewards and department leads on system use
- Establish clear data submission timelines and escalation processes
- Communicate benefits to encourage adoption
Cost Considerations
Typical Cost Structure
- Implementation/setup: $50,000–$500,000+ depending on vendor, complexity, integration requirements
- Annual subscription: $30,000–$500,000+ per year depending on number of users and data volume
- Training and support: Often additional, though may be bundled
Total 3-year cost typically ranges $200,000–$2+ million depending on organisation size and implementation scope.
ROI Considerations

- Reduced audit risk and assurance costs (better data governance)
- Improved data quality reducing errors and restatements
- Scalability supporting future growth
- Team efficiency allowing smaller ESG team to manage reporting
Frequently Asked Questions
Is ESG reporting software necessary for AASB S1/S2 compliance?
Not strictly necessary, but highly recommended. Spreadsheet-based systems carry significant data governance risk that external assurance providers will scrutinise. ESG software provides controls and audit trails supporting compliance and assurance.
Can we start with a spreadsheet and upgrade later?
Yes, but plan to migrate within the first 1–2 reporting cycles. Starting with spreadsheet is acceptable for initial preparation, but investing in proper ESG software before your mandatory reporting deadline is prudent.
Should we wait for perfect software or start with available options?
No perfect ESG software exists for all organisations. Select a good-fit vendor and plan to evolve your processes within that system as you learn from first-year reporting. Software enhancements and new features are common.
What if our parent company uses a different ESG system?
Many multinational organisations use one global ESG system while allowing regional or subsidiary flexibility. Consult your parent company on requirements and see if you can integrate into global system or maintain separate system with data reconciliation/consolidation.
Moving Forward with ESG Software Selection
Selecting and implementing ESG reporting software is a strategic investment in data governance and reporting efficiency. Given AASB S1/S2 compliance deadlines, organisations should begin evaluation and selection now if not already done. A well-chosen system streamlines reporting, reduces audit risk, and provides foundation for continuous improvement of ESG performance and transparency.
