Carbon Accounting 101: A Guide for Small Businesses

Carbon accounting – measuring your organisation’s greenhouse gas emissions – is the foundation of any climate action plan. For small and medium‑sized enterprises (SMEs), it may seem daunting, but it doesn’t have to be. With the right approach, you can start small, learn quickly, and build momentum.

What Is Carbon Accounting?

Carbon accounting quantifies the amount of carbon dioxide (and other greenhouse gases) that your business releases into the atmosphere. It follows the international standard GHG Protocol, which categorises emissions into three scopes:

• Scope 1: Direct emissions from sources you own or control (e.g., company vehicles, on‑site fuel combustion).
• Scope 2: Indirect emissions from the generation of purchased electricity, steam, heating, and cooling.
• Scope 3: All other indirect emissions in your value chain (e.g., business travel, waste, purchased goods, logistics).

Getting Started

For most SMEs, the best starting point is to focus on Scopes 1 and 2, as they are easier to measure and manage. Here’s a simple roadmap:

1. Identify emission sources: List all fuel‑burning equipment, company vehicles, and electricity meters.
2. Collect data: Gather utility bills, fuel receipts, and mileage logs. Use average emission factors (available from government and industry bodies).
3. Calculate: Multiply activity data (e.g., kWh, litres) by the appropriate emission factor.
4. Review and report: Compile your inventory and identify reduction opportunities.
