The embeddedness of sustainability in the construction industry: Identifying key drivers and barriers to implementation

Abstract

Sustainable buildings play a critical role in mitigating climate change. Despite the growing significance of the sustainability agenda driven by EU decarbonization targets, the integration of sustainability criteria in decision-making remains limited. In this study, key factors influencing the implementation of sustainability are identified based on data from an empirical study conducted with construction industry experts in November 2022. Focus groups, comprising real estate project managers, architects, engineers, construction managers, real estate brokers, real estate appraisers, and researchers were engaged to analyze the drivers and barriers to sustainability adoption in practice. Legal regulations, company reputation, and stakeholder demand are recognized as pivotal factors driving the integration of sustainability within the construction industry. Conversely, the main causes for limited implementation are linked to deficiencies in the legislative framework, financial considerations, late adoption of sustainable practices, and lack of awareness among stakeholders. The study reveals a significant impact of legislation, emphasizing that the most substantial influence on sustainability implementation derives from national regulations and international directives, which highlights the imperative to comprehensively integrate various aspects of sustainability within regulatory frameworks. To overcome financial constraints, it is imperative to offer financial incentives and address the prevailing perception gap by substantiating the long-term financial benefits of sustainable buildings to stakeholders, supported by empirical research.
