How Small and Medium Businesses in Australia Can Start Their Carbon Accounting Journey
Introduction: Why Carbon Accounting is a Must for SMBs
For years, carbon accounting was seen as a responsibility of large corporations with substantial sustainability budgets. But as climate regulations, consumer preferences, and business expectations evolve, small and medium-sized businesses (SMBs) in Australia can no longer afford to ignore their carbon footprint.
Why? Because carbon accounting is not just about compliance—it’s a strategic tool for cost savings, investment opportunities, competitive advantage, and long-term business growth.
Consider this:
✔ Energy prices are rising – SMBs that track and optimize energy usage cut costs significantly.
✔ Supply chains are getting stricter – Large companies and government contracts require carbon reporting from suppliers.
✔ Customers are demanding sustainability – More Australians are choosing to support eco-conscious businesses.
✔ Investors and lenders are shifting focus – Banks and investors favor businesses with clear carbon reduction strategies.
The good news? SMBs don’t need to become climate scientists or hire expensive consultants to start their carbon accounting journey. By taking simple, practical steps, businesses can measure their emissions, set reduction goals, and improve profitability without overwhelming complexity.
This guide provides a detailed step-by-step approach to help SMBs start carbon accounting, reduce emissions, and position themselves as leaders in Australia’s low-carbon economy.
1. What is Carbon Accounting? A Simple Overview for SMBs
A. Understanding Carbon Accounting
Carbon accounting is the process of measuring, tracking, and reporting a business’s greenhouse gas (GHG) emissions. It helps businesses understand where emissions come from, how to reduce them, and how to report progress transparently.
Emissions are typically measured in carbon dioxide equivalent (CO₂e), which includes:
✔ Carbon dioxide (CO₂) from burning fossil fuels
✔ Methane (CH₄) from waste, agriculture, and energy production
✔ Nitrous oxide (N₂O) from industrial activities and fuel combustion
B. The Three Scopes of Carbon Emissions
To ensure consistency, carbon emissions are classified into three scopes under the Greenhouse Gas Protocol:
✔ Scope 1 (Direct Emissions): Emissions from sources owned or controlled by the business.
• Examples: Fuel from company vehicles, gas-powered appliances, industrial processes.
✔ Scope 2 (Indirect Energy Emissions): Emissions from purchased electricity, heating, and cooling used in business operations.
• Examples: Electricity bills from offices, retail stores, or warehouses.
✔ Scope 3 (Value Chain Emissions): Indirect emissions from sources outside a company’s direct operations but linked to its activities.
• Examples: Supplier emissions, business travel, waste disposal, shipping, and product end-of-life impact.
Key Takeaway: SMBs should focus first on Scope 1 and 2 emissions, as they are easier to track and can lead to immediate cost savings. Scope 3 can be addressed later as businesses gain more carbon accounting experience.
2. How to Start Carbon Accounting in Your SMB: A Step-by-Step Guide
Step 1: Identify Data Sources and Gather Emissions Data
SMBs don’t need complex tools or consultants to start measuring emissions. The best approach is to begin with simple data sources and refine over time.
A. Collecting Business Data for Carbon Accounting
✔ Energy Usage: Gather electricity and gas bills from the past 12 months.
✔ Fuel Consumption: Record company vehicle fuel use and business mileage.
✔ Business Travel: Track flights, car rentals, taxis, and employee commutes.
✔ Supply Chain Emissions: Work with suppliers to understand their carbon footprint.
✔ Waste & Water Usage: Monitor waste disposal and recycling habits.
B. Tools to Convert Data into CO₂e Emissions
Once you have raw data, convert it into carbon dioxide equivalent (CO₂e) using:
✔ Australia’s National Greenhouse Accounts (NGA) Factors – Government-provided emissions conversion factors for fuel, electricity, and waste.
✔ Online Carbon Calculators – The Climate Active Carbon Calculator helps SMBs estimate emissions based on industry standards.
✔ Carbon Accounting Software – SMB-friendly tools like Sumday, Persefoni, Envizi, or Sphera automate emissions tracking.
Key Takeaway: Start small, using available data sources. Refinements can be made as your carbon accounting system evolves.
Step 2: Set Clear Carbon Reduction Goals
Once emissions are measured, businesses must set realistic, measurable goals to track progress.
✔ Short-Term (6-12 months): Reduce electricity usage by 10-15% by switching to LED lighting and energy-efficient appliances.
✔ Medium-Term (1-3 years): Cut fuel-related emissions by transitioning to hybrid/electric vehicles or optimizing logistics.
✔ Long-Term (5+ years): Work toward 100% renewable energy adoption and sustainable supply chain partnerships.
Key Takeaway: Goals should be specific, actionable, and time-bound, aligning with business priorities and financial feasibility.
Step 3: Implement Carbon Reduction Strategies
Reducing emissions doesn’t require massive investments. Many simple, low-cost strategies deliver immediate savings while benefiting the environment.
A. Reduce Energy Consumption
✔ Upgrade to LED lighting, energy-efficient appliances, and smart thermostats.
✔ Install motion sensors for lighting in low-traffic areas.
✔ Work with landlords to negotiate green energy supply contracts.
B. Optimize Transportation & Logistics
✔ Encourage remote work and virtual meetings to reduce business travel.
✔ Use route optimisation software to reduce fuel consumption in company vehicles.
✔ Switch to electric or hybrid company cars when replacing fleet vehicles.
C. Engage Suppliers & Reduce Scope 3 Emissions
✔ Work with suppliers that prioritise sustainability to reduce upstream emissions.
✔ Encourage vendors to use low-carbon packaging and shipping methods.
✔ Implement a waste reduction and recycling program in the office.
Key Takeaway: Even small, low-cost improvements lead to significant emissions reductions and financial savings.
Step 4: Report Progress & Communicate Sustainability Efforts
A. Internal & External Reporting
✔ Track progress internally using simple spreadsheets or cloud-based sustainability tools.
✔ Communicate carbon reduction efforts in annual reports, websites, and marketing materials.
✔ Engage employees with sustainability challenges and workplace initiatives.
B. Reporting Options for SMBs in Australia
✔ Climate Active Certification – A government-backed carbon-neutral certification program.
✔ B Corp Certification – Ideal for purpose-driven businesses wanting sustainability recognition.
✔ Corporate Sustainability Reports – Recommended for SMBs working with large corporations that require emissions reporting.
Key Takeaway: Transparency builds trust—reporting your efforts enhances brand reputation, customer loyalty, and business credibility.
3. The Business Benefits of Carbon Accounting for SMBs
✔ Lower Operating Costs – Energy and fuel efficiency leads to direct financial savings.
✔ Competitive Advantage – Businesses that disclose emissions win more contracts and partnerships.
✔ Stronger Brand Reputation – Consumers prefer brands that demonstrate real climate action.
✔ Access to Green Finance – Banks and investors offer better loan terms to low-carbon businesses.
✔ Future-Proofing Against Regulations – Early adoption of carbon tracking ensures compliance with upcoming climate laws.
Key Takeaway: SMBs that take action today will have a business advantage tomorrow.
Conclusion: Start Small, Act Now, and Scale Up
Carbon accounting isn’t just for large corporations—SMBs in Australia have much to gain by starting now.
✔ Measure emissions using existing business data.
✔ Set realistic, achievable reduction targets.
✔ Take simple, cost-effective steps to cut emissions.
