Although numerous scientific studies have extensively analyzed religion's impact on environmental performance at the firm level, the literature on environmental effects at a country level is relatively poor. This paper aims to fill this gap by studying how the dimensions of national culture, including religion, impact a country's sustainability performance in 96 countries. We apply Geert Hofstede's cross-cultural dimensions and evaluate
countries' sustainability performance using the EPI indicator, which provides a comprehensive environmental overview, including indicators such as climate change, environmental health, and ecosystem vitality. Additionally, to provide a more comprehensive framework for the sustainability performance of countries, we conducted a comparative analysis using the SDG index scores encompassing 1056 country-year observations.
Our findings suggest that the impact on a country's environmental performance varies according to the cultural dimension, mainly, the Christian religion positively influences national sustainability performance.
