The study investigates the impact of cultural values on business executives’ actions regarding corporate sustainable development (CSD) in Greece. Corporate sustainable development is examined as an integrated construct of three dimensions (environmental, economic and social development), and organizational culture is used as a control variable, among others, to assess the relationship between sustainability and cultural values. The survey on the CEOs of medium- and large-sized firms reveals that two of the six Hofstede’s cultural dimensions, long-term orientation and collectivism, have a significant effect on executives’ actions concerning corporate sustainable development. Specifically, collectivism is negatively related to corporate sustainable development, while long-term orientation is positively related. Moreover, the results indicate that organizational culture and a firm’s size are significantly associated with corporate sustainable development practices.
