What Are Scope 1, 2, and 3 Emissions? A Malaysian SME Guide

As global buyers and financial institutions tighten carbon reporting mandates, Malaysian small and medium enterprises (SMEs) face increasing pressure to quantify their carbon footprint. Whether aligning with the Ministry of Investment, Trade and Industry’s (MITI) National Industry Environmental, Social, and Governance Framework (i-ESG) or Capital Markets Malaysia’s (CMM) Simplified ESG Disclosure Guide (SEDG), understanding Greenhouse Gas (GHG) Protocol emissions is essential for export market access and supply chain retention.

GHG emissions are categorized into three distinct buckets: Scope 1, Scope 2, and Scope 3. Here is a practical breakdown tailored to Malaysian businesses.

---

1. Scope 1: Direct Greenhouse Gas Emissions

Scope 1 emissions refer to direct carbon releases from sources owned or controlled by your organization.

Common Examples for Malaysian SMEs:

* Stationary Combustion: Diesel, petrol, or natural gas burned in industrial boilers, generators, or machinery in your Shah Alam or Pasir Gudang facility. * Mobile Combustion: Fuel consumed by company-owned delivery trucks, forklifts, or corporate vehicles. * Fugitive Emissions: HFC refrigerant leaks from commercial air-conditioning and cold storage units.

2. Scope 2: Indirect Energy Emissions

Scope 2 covers indirect emissions associated with the generation of purchased energy consumed by your business.

Common Examples for Malaysian SMEs:

* Purchased Electricity: Electricity bought from utility providers such as Tenaga Nasional Berhad (TNB), Sabah Electricity Sdn Bhd (SESB), or Sesco in Sarawak.

*Note:* Calculating Scope 2 requires applying local Grid Emission Factors (expressed in $\text{kg CO}_2\text{e/kWh}$) published by the Energy Commission (*Suruhanjaya Tenaga*) or Malaysia Green Technology and Climate Change Corporation (MGTC).

3. Scope 3: Indirect Value Chain Emissions

Scope 3 encompasses all other indirect emissions occurring across your upstream and downstream value chain. Although challenging to track, Scope 3 typically represents 70% to 90% of an enterprise’s total carbon footprint.

Priority Categories for Local Supply Chains:

* Category 1 (Purchased Goods & Services): Extraction and production of raw materials bought from local or international tier-2 suppliers. * Category 4 & 9 (Upstream & Downstream Logistics): Freight and distribution managed by third-party logistics (3PL) providers across Peninsular and East Malaysia. * Category 5 (Waste Generated in Operations): Off-site disposal and treatment of industrial waste and municipal trash.

Why Scope Categorization Matters for Malaysian Businesses

1. MITI i-ESG Compliance: Phase 1 of the i-ESG framework emphasizes capacity building, while Phase 2 mandates reporting for manufacturing SMEs. Accurately mapping Scopes 1 and 2 is your baseline entry requirement. 2. Access to Green Financing: Malaysian banks (such as Maybank, CIMB, and RHB) require verified Scope 1 and 2 metrics to unlock Sustainability-Linked Loans (SLLs) and Green Technology Financing Schemes (GTFS). 3. EU CBAM & Global Supply Chain Readiness: Export-oriented SMEs sending goods to Europe, Japan, or North America must disclose carbon metrics to tier-1 buyers bound by the EU Carbon Border Adjustment Mechanism (CBAM).

4 Actionable Steps to Start Scope Accounting

1. Establish Organizational Boundaries: Define whether your reporting uses operational control or financial control approaches. 2. Gather Primary Data: Collect 12 months of utility invoices (TNB bills), vehicle fuel receipts, and gas meter readings. 3. Use the CMM SEDG Standard Disclosures: Utilize the basic disclosure templates provided in CMM’s Simplified ESG Disclosure Guide to categorize baseline metrics. 4. Automate via Local ESG Software: Replace manual spreadsheets with digital carbon accounting solutions calibrated to Malaysian grid emission factors and local regulatory frameworks.
