In the current global trade environment, sustainability requirements across supply chains are strengthening. Climate action, the Carbon Border Adjustment Mechanism (CBAM), and ESG regulations drive this shift. For SMEs, adopting an Environmental Management System (EMS) is a survival strategy. ISO 14001, developed by the International Organization for Standardization (ISO), goes beyond compliance. It also functions as a strategic signal to support overseas market entry and buyer trust. This study reviews the structure and core principles of ISO 14001:2015 from a PDCA perspective. It derives the strategic value of ISO 14001 for SME export performance through a systematic review and theoretical analysis of prior studies. It also defines five key industries: automotive, semiconductors, chemicals and petrochemicals, steel, and textiles and apparel. It examines how SMEs can operate ISO 14001 by aligning OEM, global buyer, and regulator requirements with the ISO 14001 management cycle. The analysis focuses on Clause 6.1 (risks and opportunities), Clause 6.2 (environmental objectives and planning), Clause 8.1 (operational planning and control), Clause 9.1 (monitoring, measurement, analysis, and evaluation), Clause 9.2 (internal audit), and Clause 10.2 (nonconformity and corrective action). This study presents four implications. First, ISO 14001 certification can help SMEs objectively demonstrate environmental performance and regulatory compliance to stakeholders. Second, SMEs can require suppliers to apply the same environmental standards and documentation system. This enables a shared evidence system for RFQs, prequalification, audits, and ESG disclosure. Third, SMEs can link risks and opportunities, operational control, performance evaluation, internal audits, and corrective and preventive actions (CAPA) to external regulations and to export and procurement indicators. This supports proactive management and improves operational efficiency and regulatory responsiveness. Fourth, such a system can support new market entry and improve the sustainability of business relationships with global buyers. Therefore, ISO 14001 can serve as a core strategic tool for strengthening SME export competitiveness. Finally, this study discusses the meaning and potential of ISO 14001 for SME export strategy. It contributes by showing how ISO 14001 can be connected to export competitiveness and by proposing practical implications under limited resources.
