STRATEGIC INTEGRATION OF ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) PRINCIPLES AND FIRM PERFORMANCE: EVIDENCE FROM MANUFACTURING COMPANIES IN NIGERIA

Abstract

ABSTRACT
This study investigates the strategic integration of Environmental, Social, and Governance (ESG)
principles and its impact on firm performance among manufacturing companies in Ogun State, Nigeria.
The study uses a mixed-methods research methodology that combines quantitative surveys and
qualitative interviews, and it is based on the Resource-Based View, Stakeholder Theory, and
Institutional Theory. About 10,000 workers in Ogun State's manufacturing companies made up the
target population. The Yamane method was used to determine a sample of 400 respondents; 368 valid
responses were examined, yielding a 92% response rate. Using stratified random sampling, companies
were chosen according to their size (small, medium, large) and industry representation (food
processing, consumer products, textiles, and cement). A structured questionnaire with open-ended and
5-point Likert scale items was used to gather data. Semi-structured interviews with managers of
particular companies, including Lafarge Africa Plc, Nestlé Nigeria Plc, Unilever Nigeria Plc, Dangote
Cement Plc, and Olam Nigeria Ltd., were also conducted. Cronbach's alpha ≥ 0.7 indicated that the
instrument was reliable, and expert assessment proved the content validity. Multiple regression
analysis, descriptive statistics, and Pearson correlation were used in the data analysis, which was
carried out using SPSS version 26. The significance criterion for testing hypotheses was set at 5% (p <
0.05). The results showed that ESG adoption strongly predicted increased value creation, operational
efficiency, and stakeholder trust, and that there was a strong and statistically significant positive
association between ESG integration and company performance (r = 0.79, p < 0.001, R² = 0.62). ESG
adoption was also strongly correlated with organizational competencies and ESG awareness (r = 0.77,
p < 0.001, R² = 0.59). These results demonstrate that in Nigeria's manufacturing industry, ESG
integration is a strategic asset that improves business competitiveness and sustainable results.
According to the study's findings, integrating ESG principles into Ogun State manufacturing companies
is not just a CSR endeavor; rather, it is a vital component of resilience and long-term performance. For
businesses looking to increase sustainability and stakeholder involvement, it suggests capacity-building
initiatives, policy incentives for ESG adoption, and strategic ESG alignment.
