Today, environmental issues and climate change are among the top agenda items for countries, while the concept of sustainable development has expanded to include environmental, economic and social dimensions. Defined by the United Nations in 1987, sustainable development emphasizes the need to meet present needs without compromising the ability of future generations to meet theirs. This study aims to evaluate the sustainability performance of D-8 Organization for Economic Cooperation member countries across five main dimensions: social, environmental, economic, governance, and financial. As sustainable development practices increase, D-8 countries, with their rapid economic growth and high population density, have the potential to adopt sustainability strategies to address the challenges they face. However, these countries are confronted with significant barriers such as poverty, health, education, and environmental challenges. This research seeks to provide substantial contributions to D-8 countries in the context of implementing sustainability dimensions. The study covers the 2014-2020 period and analyzes the sustainability performance of D-8 countries using multi-criteria decision-making (MCDM) methods. In the analysis phase, the relative importance levels of sustainability performance indicators were first determined using the Lopcow method. Following this, based on these importance levels, the countries' sustainability performances were ranked using the Mabac, Mairca, and Codas methods. In the final stage, the performance scores calculated by these three methods were integrated into a single ranking using the Borda Count method. The analysis results show that Malaysia, Indonesia, and Türkiye ranked as the top three countries, with the highest sustainability performance, while Egypt, Nigeria and Iran were the countries with the lowest performance.
