Sustainable Practices of Multinational Construction Companies, Lagos, Nigeria

Abstract

This study evaluated the sustainable practices of multinational construction companies (MCCs) in Lagos State, Nigeria, with a view to promoting sustainable development and achieving a sustainable future. A total of 150 structured questionnaires were administered to selected multinational construction companies, yielding a response rate of 47%. The collected data were analysed using frequency distribution and mean score techniques to classify respondents’ perceptions of sustainability practices. Analysis of Variance (ANOVA) was employed to determine significant differences in respondents’ opinions, while factor analysis was used to identify the underlying factors influencing sustainable practices. The findings revealed a high level of engagement by multinational construction companies in sustainable practices, including corporate social responsibility and ethical practices, installation of energy-efficient mechanical and electrical systems, reduction in the use of hazardous materials on construction sites, minimization of construction waste, and energy conservation in company operations. The study further identified cost effectiveness and financial gains, stakeholders’ understanding, access to sustainable technologies, operational and economic considerations, and corporate image and value delivery as the most influential factors driving sustainability adoption. The study concluded that multinational construction companies in Lagos State are actively implementing practices that contribute to environmental sustainability and the well-being of future generations. However, financial and cost-related constraints remain significant barriers to the effective implementation of sustainable practices within the construction sector.
