Climate-related Scenario Analysis Disclosures by JSE Basic Resources Companies – Too Hot to Handle

Dr. Leana Esterhuyse, Johanna Nel

ABSTRACT:

This study investigates climate-related scenario analysis (CRSA) disclosures by Johannesburg Stock Exchange (JSE)-listed basic resource companies, focusing on alignment with the Task Force on Climate-related Financial Disclosures (TCFD) and the International Sustainability Standards Board (ISSB)’s IFRS S2 standards. Using an exploratory research design, content analysis of all 32 basic resources companies’ 2023 integrated and climate-related reports was conducted. A CRSA checklist was developed based on IFRS S2 to evaluate alignment, complemented by qualitative insights to contextualise findings. We then compare disclosures by the ten largest companies with those of smaller entities to assess the influence of resources and skills. While nine of the ten largest companies were fully aligned with IFRS S2, only half of the basic resource companies disclosed CRSA information. Smaller companies exhibited inconsistent compliance, reflecting potential resource and skills constraints. Larger companies responded more effectively to stakeholder expectations, using CRSA to signal strategic resilience. The findings emphasize that resources and expertise strongly influence disclosure practices. The study highlights the need for capacity-building initiatives to support smaller companies in developing economies. Policymakers and investors should address barriers to adoption, balancing global reporting consistency with local challenges. This research expands the literature on CRSA in developing contexts, providing unique insights into South Africa and the challenges and opportunities faced by its basic resource companies. The study contributes to understanding how resource constraints drive heterogeneity in CRSA disclosure in emerging markets and offers practical recommendations to improve alignment with emerging global climate disclosure standards.
