Abstract: Environmental impact assessment (EIA) is a systematic study for identification and evaluation of potential impacts or effects of the proposed projects, programs, processes, plans, legislative actions relative to physical, chemical, biological , radio-active and socio-economic environment with respect to total environment. EIA Studies have been carried out in some hazardous industries and cleaner and greener production have been recommended. Cleaner technologies can be defined as technologies that can produce the same output of unclean technologies by causing less damage to the environment. Cleaner technologies as those that are less polluting, use resources in a sustainable manner, recycle more of their wastes and products and handle all residues in a more environmental acceptable way than the technologies for which they are substitutes. Greener technologies can be defined as technologies that can produce less output of unclean technologies by causing no damage to the environment.
The need is to conserve the living planet with any rational approach. It is urgently required to deal with the issues that are closely related to our surroundings, and suggested techniques preferably with local resources and know-how, to make that more sensibly habitable. This article realizes the environmental impact assessment of some hazardous industries and emphasizes the need of cleaner and greener technology applications in order to reduce green house emissions.
