"Calculate your carbon footprint" is often the first — and most intimidating — request an SME gets from an ESG-conscious buyer or bank. It sounds technical, but the underlying data is usually already sitting in your utility bills and fuel receipts. The work is in structuring it correctly.

Scope 1 and Scope 2: the two numbers that matter first

  • Scope 1 — direct emissions from sources your company owns or controls: company vehicles, generators, on-site fuel combustion.
  • Scope 2 — indirect emissions from purchased electricity: essentially, your electricity bill converted into an emissions figure using a standard grid emission factor.

For most SMEs, Scope 1 and Scope 2 together cover the overwhelming majority of what a first ESG disclosure needs. Scope 3 (emissions from your wider supply chain) is a more advanced step most SMEs aren't expected to tackle in their first report.

The data you probably already have

  • Monthly electricity bills — the foundation of your Scope 2 calculation.
  • Fuel purchase records — for company vehicles, generators or on-site equipment (Scope 1).
  • Utility meter readings — useful for cross-checking billed amounts.

Start tracking these monthly if you aren't already — even basic, consistent records provide a workable foundation for a first carbon footprint calculation.

How the calculation actually works

At its simplest: activity data (litres of fuel, kWh of electricity) is multiplied by a standard emission factor for that activity or fuel type, producing a CO₂-equivalent figure. Some organisations go further and pursue ISO 14067 (Carbon Footprint of Product) certification to strengthen the credibility of their Environmental pillar disclosures — a more advanced step once the basic Scope 1/2 calculation is established.

Where this fits your broader ESG disclosure

A carbon footprint figure is one input into the wider Environmental section of an ESG disclosure — for Malaysian SMEs, often reported through the Simplified ESG Disclosure Guide (SEDG) framework when responding to a listed-company buyer's request. It's also one of the concrete deliverables in our ESG Adoption Program for SMEs, alongside the full Sustainability Report.

Frequently asked questions

Do SMEs need to calculate Scope 3 emissions?

Not typically for a first disclosure. Scope 1 (direct) and Scope 2 (purchased electricity) emissions are the standard starting point; Scope 3 (supply-chain emissions) is a more advanced step most SMEs aren't expected to tackle initially.

What data do we need before we start?

Monthly electricity bills and fuel purchase records for company vehicles, generators or equipment are the core inputs for a first Scope 1 and Scope 2 calculation.

Is a carbon footprint calculation the same as a full Sustainability Report?

No. The carbon footprint calculation is one component within the Environmental pillar of a broader Sustainability Report, which also covers Social and Governance disclosures.
