The construction projects and activities generate waste materials, which impose negative impacts on the environment and contribute towards environmental degradation. In this regard, the implementation of environmental practices (EPs) can play a vital role in reducing the environmental risks associated with waste materials from construction projects. Based on this hypothesis, the present survey study was conducted to assess the effectiveness of different EPs in reducing environmental risks associated with waste materials from construction firms (n = 159) operating in Pakistan. Organizational and government support, regulatory pressure, and economic and environmental performance were among the main determinants of EPs studied in the present study. The partial least squares technique was used for the data collection, assessment, and prediction of the results based on the hypothesis testing for a range of determinants. Compose reliability analysis of determinants showed that all items gave a value of 0.7, which is a clear indication of the reliability of each determinant in the formation of the hypothesis. From all eight hypotheses, H (0.475), H (0.217), H (0.114), H (0.210), and H (0.149) hypotheses with size effect in parentheses were acceptable due to their positive construction with EPs, while H, H, and H hypothesis did not show the significant effect with size effect values lower than 0.1. The study demonstrated that current environmental regulations and governing bodies in Pakistan are not sufficiently effective and strict to implement environmental regulations. In this regard, regulatory pressure is necessary to promote EPs along with increasing stakeholders' awareness. Overall, the implementation of EPs not only prepares construction firms to deal with the pressure exerted by regulations and customers but also enhances the environmental and economic performance of construction firms.
建筑项目和活动会产生废料，对环境造成负面影响，导致环境恶化。在这方面，实施环境实践（EP）可以在减少与建筑项目废料相关的环境风险方面发挥重要作用。基于这一假设，本调查研究旨在评估不同 EP 在减少巴基斯坦建筑公司（n=159）产生的废料相关环境风险方面的有效性。本研究研究的主要决定因素包括组织和政府支持、监管压力以及经济和环境绩效。偏最小二乘法技术用于数据收集、评估和根据假设测试结果进行预测，以测试一系列决定因素。对决定因素的可靠性分析表明，所有项目的价值均为 0.7，这清楚地表明了每个决定因素在假设形成中的可靠性。在所有八项假设中，由于 EP 的积极构建，H（0.475）、H（0.217）、H（0.114）、H（0.210）和 H（0.149）假设具有可接受的正效果，而 H、H 和 H 假设则由于其大小效应值低于 0.1，并未显示出显著效果。研究表明，目前巴基斯坦的环境法规和管理机构不够有效和严格，无法实施环境法规。在这方面，需要监管压力来促进 EP 的实施，同时提高利益相关者的意识。总的来说，实施 EP 不仅使建筑公司能够应对法规和客户施加的压力，还提高了建筑公司的环境和经济绩效。
