ESG Reporting for SMEs in Australia: A Simplified Approach

ESG Reporting for SMEs in Australia: A Simplified Approach

While mandatory AASB S1 and S2 reporting applies primarily to large entities and ASX-listed companies, many Australian SMEs face pressure from customers, suppliers, or investors to report on ESG matters. This guide provides a practical, scaled-down approach to ESG reporting for SMEs not yet subject to mandatory compliance.

For comprehensive ESG strategy context, see our complete ESG guide for Australian businesses.

Are SMEs Required to Report on ESG?

Mandatory Reporting Thresholds

AASB S1 and S2 mandatory reporting applies to:

  • Group 1 (FY2025–26): ASX-listed companies, entities with consolidated assets ≥$250m or revenue ≥$500m, NGER reporters
  • Group 2 (FY2026–27): Entities with consolidated assets ≥$100m or revenue ≥$200m
  • Group 3 (FY2027–28): Smaller reporting entities under Corporations Act

Most SMEs fall below Group 3 thresholds and are not subject to mandatory AASB reporting.

Voluntary Reporting Drivers for SMEs

Even without mandatory requirements, SMEs may face ESG reporting pressure from:

  • Customer expectations: Large corporate customers increasingly require suppliers to report on ESG (particularly emissions)
  • Investor/lender requirements: Banks and investors increasingly scrutinise ESG, particularly regarding climate and governance risks
  • Competitive differentiation: ESG leadership can attract customers, talented employees, and investment
  • Supply chain participation: If your customers are Group 1–3 entities, they may require your Scope 3 emissions data
  • Industry standards: Some industries (mining, agriculture, food) have industry associations or peers setting ESG reporting expectations

Voluntary ESG Reporting Frameworks for SMEs

GRI Standards

GRI is the most widely adopted voluntary framework. SMEs can report against GRI Universal Standards and Topic Standards relevant to their business.

Advantages for SMEs:

  • Flexible—report only on material topics
  • Global credibility—investors and customers recognise GRI
  • Comprehensive—covers all ESG areas
  • No size restrictions

Typical scope for SMEs: Focus on 5–10 material topics rather than comprehensive 300+ topic coverage. Publish concise report (10–20 pages) addressing governance, most material environmental and social topics, metrics, and targets.

TCFD Framework

TCFD focuses specifically on climate risk governance and disclosure. Many SMEs report against TCFD or incorporate TCFD-style climate disclosure into general ESG reporting.

Advantages for SMEs:

  • Climate-focused (often most material ESG topic for SMEs)
  • Relatively straightforward four-pillar structure
  • Increasingly expected by investors and customers

CDP Disclosure

CDP operates questionnaire-based disclosure platform for climate, water, and forests. SMEs can participate if customers or stakeholders require.

Advantages for SMEs:

  • Structured questionnaire makes reporting straightforward
  • Investor recognition (major investors subscribe)
  • Can start with just climate disclosure

Australian Industry Standards

Some Australian industries have developed ESG guidance or standards. Examples:

  • Farming: Australian Organic, various industry associations
  • Manufacturing: Various peer groups and industry bodies
  • Retail/Food: Supply chain ESG expectations from major retailers

Check if your industry has established ESG guidance or standards.

Simplified ESG Reporting Approach for SMEs

Step 1: Assess Why You’re Reporting

Before investing in reporting, understand motivation:

  • Customer/supplier requirements?
  • Investor/lender expectations?
  • Strategic positioning and competitive advantage?
  • Internal governance and risk management?

This shapes which framework and scope makes sense for your business.

Step 2: Identify 5–10 Material Topics

SMEs don’t need comprehensive materiality assessment. Simple approach:

  • Identify material topics through informal stakeholder engagement (talk to customers, employees, investors about ESG concerns)
  • Consider which ESG issues affect your financial performance or create risk/opportunity
  • Consider which ESG impacts are most significant (environmental, social, governance)
  • Select 5–10 topics as material for your business

Common material topics for SMEs: emissions/climate, energy use, waste, water, employee safety, diversity, ethics/compliance.

Step 3: Collect Basic Data

For each material topic, collect baseline data:

  • Emissions: Energy bills, fuel records (estimate Scope 1 & 2 using GHG Protocol or simple spreadsheet)
  • Workforce: Employee count, turnover, any diversity data you track
  • Safety: Incidents, near-misses, lost time
  • Governance: Board composition, management structure, ethics policies

Data doesn’t need to be perfect—use best available information and disclose limitations.

Step 4: Write Simple Report or Disclosure

Format options:

  • Standalone report: 10–20 page ESG report (may be attached to annual report)
  • Website disclosure: ESG information on company website with downloadable factsheet
  • Annual report inclusion: Expand Directors’ Report to include ESG narrative and data
  • Questionnaire response: Complete customer or investor ESG questionnaire

Typical structure:

  • Opening: Explanation of why ESG matters to your business
  • Governance: Board oversight, policies, ethics
  • Material topics: One section per material topic (governance, management approach, metrics, targets)
  • Data appendix: Detailed metrics, calculations, assumptions

Step 5: Communicate

  • Share report with customers, investors, employees, stakeholders
  • Use to differentiate from competitors
  • Build into marketing and business development messaging

Addressing Specific SME Challenges

Challenge: Limited Resources

Solution: Start small. Focus on 5–10 material topics, not comprehensive reporting. Use internal resources initially; consider hiring external support for specific areas (emissions calculation, data management) rather than full reporting project.

Challenge: Customer ESG Questionnaires

Many SMEs find large corporate customers request ESG data through lengthy questionnaires.

Solutions:

  • Allocate someone to complete questionnaires (often 2–4 hours per questionnaire)
  • Build answers once, reuse across different questionnaires with minor modification
  • Use publicly available ESG questionnaire platforms to see what others report
  • Be transparent about data limitations

Challenge: Supply Chain Pressure for Emissions Data

Increasingly, large customers request Scope 1 & 2 emissions data from suppliers.

Solutions:

  • Calculate emissions using GHG Protocol guidance and energy/fuel records
  • Use simple spreadsheet or free online tools to track and calculate
  • Share calculation methodology with customers so they can verify reasonableness

Future-Proofing Your SME ESG Approach

Monitor Regulatory Changes

AASB reporting thresholds apply now only to large entities, but may expand to smaller entities over time. SMEs should:

  • Monitor AASB announcements and government consultations on reporting expansion
  • Review your size and growth trajectory—if you’re approaching Group 3 thresholds, begin preparing for mandatory compliance within 2–3 years
  • Establish governance structures and data systems now so compliance is straightforward when required

Build Data Foundations

Even if not currently required to report, SMEs benefit from establishing:

  • Annual tracking of emissions, energy, waste (data can support future reporting and operational efficiency)
  • Employee and workforce data tracking
  • Documentation of policies and governance

Engage Stakeholders Progressively

Use voluntary reporting to build relationships with investors, customers, employees around ESG. This positions you well if reporting becomes mandatory or if stakeholder expectations increase.

Frequently Asked Questions

Do SMEs need to report on ESG if not mandatory?

Not legally required, but business pressure (customer requirements, investor expectations, competitive differentiation) may drive voluntary reporting. Assess whether reporting provides value for your specific business.

What if we can’t measure emissions accurately?

Use available data (energy bills, fuel records, employee numbers) and reasonable estimates. Disclose limitations. Commitment to improve over time is valuable to stakeholders.

How much time/cost for SME ESG reporting?

Simplified voluntary reporting (5–10 topics, basic data) typically requires 100–200 internal hours plus external support (if needed) costing $5,000–$20,000. Much less than mandatory compliance requirements for larger entities.

Will being an SME reduce assurance requirements?

Assurance is not mandatory for SME voluntary reporting. However, external assurance enhances credibility if pursuing ESG for competitive advantage.

Moving Forward with SME ESG Strategy

SMEs can benefit significantly from voluntary ESG reporting without the complexity or cost of mandatory compliance. Simplified approaches focusing on material topics, basic data collection, and transparent disclosure build stakeholder trust and competitive advantage. As your business grows or regulatory requirements change, the governance and data foundations you establish now support scaling to more comprehensive reporting.
