Corporate social responsibility and sustainable management of solid wastes and effluents in Lagos megacity Nigeria

Purpose: This study aims to empirically investigate the relationship between corporate social responsibility (CSR) and sustainable management of wastes and effluents (SMWE) in Lagos Megacity. Design/methodology/approach: The paper adopts a quantitative research method, specifically the use of a Web-survey technique for eliciting responses from a cross-section of companies affiliated to the Lagos Chambers of Commerce and Industry (LCCI). From a target population of 2,300 companies, a sample of 92 companies was drawn using the sample determination formula of Parten (1950). The 92 sampled companies were randomly administered Web-based questionnaires through their official emails. Finally, the 56 responses received from the participating companies (corresponding to 61 per cent response rate) were analysed electronically and the results presented using descriptive and inferential statistics. Findings: The results show strong positive relationships between CSR and advocacy on waste and effluents (0.7), environmental impact response (0.7), environmental sustainability policy (0.6) and preventive negative impact (0.6) with P < 0.05. However, weak positive relationships exist between CSR and monitoring mechanisms (0.3) and adequacy of infrastructure for wastes and pollutants management (0.4). Overall, there is a significant positive relationship between CSR and sustainable management of solid wastes and effluents in the sampled companies in Lagos. Research limitations/implications: The research is limited to Lagos Megacity because it is the industrial and commercial hub of Nigeria. Besides, there are several industrial associations in Lagos, but the selected association was the LCCI with 56 sampled companies. Practical implications: The research supports and validates the theory of planned behaviour (TPB), which explicates that performance behaviour of organisations is influenced by the behavioural intention and behavioural control. However, behavioural intention of organisations may be carried out, abandoned or revised based on ever changing circumstances or contexts. Originality/value: The study bridges the gap between theory and practice of environmental CSR by enriching the understanding of academics and practitioners on CSR and environmental sustainability relationships in Lagos Megacity.
