Iran is one of the countries applying for accession to the World Trade Organization (WTO) and currently has observer status. Accordingly, given the time left, it should comply with environmental laws and regulations and design the pattern of trade with other countries to be consistent with environmental criteria and standards. In this regard, the present study was carried out to investigate the opportunities and obstacles of Iran’s accession to the WTO. For this purpose, the key strengths, weaknesses, opportunities, and threats toward presenting an environmental management plan for Iran’s accession to the WTO were initially examined using matrices for external factor evaluation (EFE) and internal factor evaluation (IFE). Thereafter, the most applicable strategies were identified through SWOT Analysis. Subsequently, the identified strategies were prioritized based on the quantitative strategic planning matrix (QSPM). The obtained results indicated that the strategies “Institutionalizing the environmental laws and regulations based on international consensus,” with a score of 5.42, and “investment in ecotourism development based on the natural attractions of Iran,” with a score of 5.38 were selected as the best strategies among the existing alternatives.
