Sustainability is increasingly turning into a strategic business project that firms are recognizing that sustainable carry outs can be economical and ought to make fresh income streams as well as enhance client and worker gratification. Despite this, sustainability and performance of firms have received little research attention. Using Natural Resource-Based View and stakeholder theory, research main purpose was to determine the mediating effect of organization culture on the association amid environmentally sustainable supply chain practices and firm performance. This study used descriptive statistics, Pearson product-moment correlation, and Structural Equation Modeling (SEM) to test the hypothesis. Data collected from 281 Kenyan manufacturing firms were used to test study hypotheses. From biascorrected bootstrapping Structural Equation Modeling, results showed that organization culture variable fully mediates the association amid environmentally maintainable supply chain methods on the performance of manufacturing firms. Thus, the study infers that a strong organizational culture in the organization leads to the enhanced implementation of environmentally sustainable supply chain practices in the organization which in turn increases the performance of manufacturing firms. Without organization culture, these practices may go unheeded and not contribute to improved performance of manufacturing firms in Kenya. Consequently, this study recommends that the managers of these firms should build an organizational culture with environmental concerns in all their processes. This study hence contributes to theory and practice by the inclusion of organizational culture and also extends natural resource-based view and stakeholder theories of a firm.

The main purpose of the study was to determine mediating effect of organization culture on the socially sustainable supply chain practices and performance of manufacturing firms. Using a survey of 281 Kenyan manufacturing firms the study tested hypotheses using PLSbootstrapping Structural Equation Modeling (SEM). From the SEM model, the results revealed that organization culture partially mediates the relationship between socially sustainable supply chain practices on performance of manufacturing firms (β=.728, p<.05). The study also concluded that for socially sustainable practices there are other underlying factors affecting the performance of manufacturing firms apart from the organization culture. This study hence contributes to sustainable supply chain management literature by the inclusion of organizational culture and also extends resource based theory, natural resource based theory and stakeholder theories of a firm. The study recommended a further study on effect of organization culture and social sustainability practices
