Owing to the on-going exhaustion of the natural environment and its consequences on the society, the present environmental state of Bangladesh, a populated country with inadequate resources, has become enormously alarming. The human health, ecosystems and economic growth are threatened by severe environmental pollutions and encroachments. Bangladesh is facing several natural catastrophes such as floods, cyclones, and tidal-bores every year because of the environmental externalities which cause severe socio-economic and ecological damage. Thus, this study aims to highlight various ecological difficulties that Bangladesh is currently facing and that pose obstacles to implementing environmental CSR for sustainable development. The review of the literature reveals that several environmental pollutions, climate change and the loss of biodiversity are continuously degrading the natural environment of Bangladesh and its resources. Consequently, these detrimental impacts are threatening the socio-economic growth of Bangladesh and its environment. Hence corporate social responsibility (particularly environmental) can play a significant role to control the current environmental degradation of Bangladesh. The government should, at the same time, undertake several initiatives to protect environmental degradation, foster the environmental CSR activities within all the business sectors and increase environmental awareness which is mandatory to attain sustainable development.
