ESG for SMEs in Southeast Asia - A Practical Guide for Malaysia, Brunei and Cambodia

The United Nations Global Compact is the world's largest corporate sustainability initiative, with over 25,000 participating companies across 100 countries. In Malaysia, Brunei, and Cambodia, the UN Global Compact is represented by UNGCMBC, the official country network that helps businesses integrate sustainability into their strategy and operations.

For SMEs operating in Malaysia, Brunei, and Cambodia, the ESG landscape looks very different from country to country. Malaysia has moved rapidly toward mandatory reporting, Cambodia is formalising its first ESG disclosure requirements, and Brunei is building voluntary frameworks aligned with its national vision. This guide provides a practical, country-by-country overview of what SMEs need to know and what steps they can take today to begin or strengthen their ESG journey.

Why ESG Matters for SMEs

Before examining the regulatory landscape in each country, it is worth understanding why ESG has become relevant for smaller businesses, not just large listed corporations.

The most immediate driver is supply chain compliance. Multinational companies with operations across Southeast Asia are under increasing pressure from regulations like the EU's Corporate Sustainability Due Diligence Directive (CSDDD) and the Carbon Border Adjustment Mechanism (CBAM) to ensure that their suppliers, regardless of size, meet certain environmental and social standards. For SMEs that supply to larger companies, particularly those exporting to Europe, demonstrating ESG practices is becoming a condition of doing business rather than a competitive advantage.

The second driver is access to finance. Financial institutions across ASEAN are integrating ESG criteria into lending and investment decisions. Banks in Malaysia, guided by Bank Negara Malaysia's Climate Change and Principle-based Taxonomy (CCPT), are increasingly assessing ESG risk when evaluating loan applications. SMEs that can demonstrate basic

ESG practices are better positioned to access green financing, sustainability-linked loans, and government grants.

The third driver is talent and reputation. Younger employees, customers, and business partners increasingly prefer to work with companies that take sustainability seriously. For SMEs competing for talent and contracts, a visible commitment to ESG can differentiate them in ways that traditional marketing cannot.

ESG Landscape: Malaysia

Malaysia has the most developed ESG regulatory framework among the three countries. The National Sustainability Reporting Framework (NSRF), launched by the Securities Commission Malaysia in September 2024, mandates IFRS S1 and S2 as baseline disclosure standards across all listed issuers and, from 2027, large non-listed companies with annual revenue of RM2 billion and above.

For SMEs, direct mandatory reporting obligations are not yet in effect. However, SMEs are increasingly affected through indirect channels. Listed companies that are required to report Scope 3 emissions must collect data from their suppliers, which means SMEs in the supply chain will be asked to provide emissions data, workplace safety records, and governance disclosures even if they are not directly regulated.

Government Support for Malaysian SMEs

The Malaysian government has introduced several incentives to help SMEs adopt ESG practices. A RM50,000 ESG reporting grant is available for companies beginning their sustainability reporting journey. Additionally, MIDA offers 50/50 matching grants of up to RM500,000 for SMEs investing in sustainable manufacturing and ESG compliance infrastructure. Tax incentives for EV charging infrastructure and green technology adoption through MGTC's Green Accelerator programme provide further financial support.

For SMEs looking to build ESG credentials without the complexity of full IFRS reporting, certifications such as ISO 14001 (environmental management), ISO 14067 (product carbon footprint), and ISO 14040/14044 (life cycle assessment) provide internationally recognised frameworks that buyers and investors understand.

UNGCMBC Support for Malaysian SMEs

UNGCMBC's SME Spotlight programme is specifically designed to help small and medium enterprises begin their sustainability journey with practical tools and peer learning. The programme recognises SMEs that are making meaningful progress in ESG adoption and provides visibility within the UNGCMBC network. Companies interested in the SME Spotlight programme can visit the programme page to learn about eligibility, benefits, and how to apply. 

ESG Landscape: Brunei

Brunei Darussalam's approach to ESG is evolving alongside its Wawasan Brunei 2035 national vision, which emphasises sustainable economic diversification and environmental stewardship. While Brunei does not yet have a mandatory ESG reporting framework comparable to Malaysia's NSRF, the government has taken several steps to encourage sustainable business practices.

The Brunei Darussalam National Climate Change Policy (BNCCP) sets the strategic direction for climate action, including commitments to reduce greenhouse gas emissions by 20% by 2030 and achieve carbon neutrality by 2050. For businesses operating in Brunei, these national targets will increasingly translate into sector-specific regulations and incentives.

For SMEs in Brunei, the most practical step is to align with international voluntary standards and build ESG capacity ahead of potential future regulations. Companies that export to markets with ESG requirements, particularly the EU and Australia, should prioritise supply chain compliance certifications and begin tracking basic environmental metrics such as energy consumption and waste generation.

As a member of the UNGCMBC network, Brunei-based companies gain access to the same sustainability resources, training programmes, and expert guidance available to Malaysian participants. The UNGCMBC Academy offers localised sustainability courses that are relevant to businesses across all three countries.

ESG Landscape: Cambodia

Cambodia represents the newest frontier for ESG adoption in the region, and it is a market where early movers have a significant advantage. The country's ESG regulatory framework is still emerging, but 2025 and 2026 have marked a turning point.

In a landmark development, Cambodia adopted a Ministerial Directive on ESG Disclosure that came into force on 10 May 2026, applying to Cambodia's listed companies. While the number of listed companies in Cambodia is still small, this directive signals the government's clear intention to formalise ESG reporting obligations across the capital markets.

Cambodia is also preparing for the adoption of IFRS S1 and S2, with full implementation planned for 2030 or later depending on entity type. In the interim, the standards provide flexibility for companies to use IFRS S1 and S2 as a reference framework for meeting the ESG Disclosure directive's requirements.

For Cambodian SMEs, the most immediate ESG pressures come from international supply chains rather than domestic regulation. Companies that manufacture for export to the EU must increasingly demonstrate compliance with the CSDDD and EUDR (EU Deforestation Regulation). Sectors such as garments, agriculture, and food processing are particularly affected.

The Cambodian Sustainable Finance Initiative (CSFI), developed by the Association of Banks in Cambodia with support from the National Bank of Cambodia and USAID, is laying the groundwork for green finance products that will eventually benefit SMEs seeking capital for sustainability investments.

Cambodia's Ministry of Environment has also launched ambitious national campaigns aligned with its Circular Strategy on Environment 2023-2028, targeting carbon neutrality by 2050 and 60% forest cover. These national priorities will shape the regulatory environment for businesses in the years ahead.
