Corporate Social Responsibility (CSR) is important and strategic businesses practice which is not only beneficial to the community, corporate shareholders and other stakeholders but also to corporate sustainability. Corporate Social Responsibility in the mining sector calls for an inclusion of social and environmental issues while pursuing economic prosperity of that particular country. For a country endowed with minerals like Tanzania, stringent regulations are needed. Incompetence of the managerial practice to implement CSR in their on-going operations, international capital and global companies have been identified as major causes for environmental pollution and growing environmental activism. There is a wide criticism among stakeholders in the sector demanding to develop plans and establish a clear strategy so as to reverse the current practices where CSR is simply being applied as a branding and marketing strategy by these companies. The literature review especially on the mining sector hardly revealed any impressive implementation and compliance requirements for CSR, particularly from environmental perspective for the best of national interests. Therefore this study examines the challenges in the practices for CSR from the environmental perspective in the mining sector in Tanzania. The methodology used in the study is meta-analysis in which various studies on CSR implementation have been reviewed. The findings on the ground indicate that there are serious challenges to comply with CSR in protecting the environment. Conclusions drawn have relevance for the real life systems and academia, particularly on integrating responsible leadership and ethical thinking in business curricular.
