The construction and building sectors are among the most significant economic sectors in Malta in terms of environmental, social and economic aspects. As world economies strive to become more sustainable, the importance of Sustainable Construction (SC) and Sustainable Development (SD) in the aforementioned economic sectors is ever more important. This study aims to address three primary research questions in the case of Malta—(i) How do Periti perceive SC and SD? (ii) What initiatives are currently in place to promote SC and SD in Malta’s construction industry? (iii) How can Education for Sustainable Development (ESD) enhance sustainable practices within the sector? Using quantitative data from a broader study, this paper provides valuable insights into the prevailing attitudes of Periti and the potential for ESD to advance sustainability in these economic sectors. The findings show a general perception among Periti that Malta’s construction sector is not developing sustainably. ESD was recognised as a critical driver for promoting SC and SD practices, with multiple opportunities for ESD initiatives being identified. Additionally, the study underscores the importance of a holistic approach that integrates ESD with broader industry efforts such as regulation, policy development and enforcement. A model proposed in the study’s conclusion illustrates the collaborative roles of public, private, and educational institutions in promoting SD in Malta’s construction sector. This study provides actionable insights to guide ESD programmes and policies aimed at enhancing sustainability within the industry.
