ABSTRACT The construction sector continues to face increasing stakeholder scrutiny to adopt sustainable practices to address the climate change issue and foster smart, sustainable cities. However, there is a paucity of empirical research investigating applications of sustainable practices to achieve sustainable project success (SPS) in the construction sector. Against this backdrop, this study provides insights into how sustainable practices can be transformed into measurable sustainability outcomes aligned with the United Nations Sustainable Development Goal (SDG) 11 and Agenda 2050. To this end, we draw on the Triple Bottom Line (TBL) perspective and Innovation Diffusion Theory (IDT) to investigate how construction firms can use sustainable practices to improve SPS, focusing on green innovation adoption (GIA) and government support for innovation (GSFI). A quantitative cross‐sectional survey of 714 construction professionals in Pakistan was analyzed using partial least squares structural equation modeling (PLS‐SEM). The results demonstrate that sustainable practices significantly improve SPS, with R 2 = 0.67, which accounts for 67% of the variance of SPS, with GIA as a mediator. Further, GSFI exerts a positive moderation effect between sustainable practices and GIA, emphasizing the critical role of policy support in promoting sustainable practices and strengthening innovation‐driven sustainability outcomes. The research provides novel insights and empirical evidence supporting the significant role of sustainable practices, GIA, and GSFI in achieving SPS within the construction sector, providing valuable insights for industry practitioners, public policymakers, and academic researchers seeking to foster sustainable, smart, and resilient cities.
