This study examines sustainability disclosures in environmentally sensitive sectors, focusing on measurement, methodological, policy enforcement, and stakeholder gaps between developed and developing nations. The objective is to examine these gaps and their implications for global comparability and credibility. Using a desk-based research design, the study reveals significant differences in disclosure practices. The findings reveal clear contrasts between developed and developing nations. Environmental criteria and metrics for measurement of carbon emission, water usage, environmental damages, climate change, vary across regions due to difference in policies, which creates inconsistencies. Methodological approaches lack patters, limiting the use of mixed methods and neglecting longitudinal data that could capture changes overtime. Policy enforcement of environmentally sensitive sectors tends to be un-unified and weaker in developing countries compared to the stronger regulatory frameworks seen in developed nations. Finally, stakeholder pressures and expectations are much higher in developed economies, driving accountability and sustainability practices, while in developing countries these pressures and expectations remain relatively low, reducing environmental obligations, encouraging voluntary and selective sustainability practices. Recommendations include that developing nations are encouraged to transition from voluntary to mandatory sustainability regimes, partner with developed nations on the basis of attainable sustainability outcomes.
