Sustainable Engineering is an eco-friendly sub-discipline that functions in ways that balance the environment in an attempt to augment materials for the future generation. It is a branch of engineering that uses resources to incur benefits and to improve living standards. Sustainable Engineering is reliable not only to Environmental Engineering but to other aspects of engineering as well. This is because existing sub-disciplines of Engineering and Technology should incorporate and organize sustainability to prevent the environment from depletion. Sustainable Engineering plays a crucial role to meet the demands of present society without compromising the needs of the future. It is a very broad discipline closely related to other disciplines like Chemistry, Biology, Technology, and Economics.

Sustainable Engineers work to ensure that the upcoming technological developments do not clash with the principles of Sustainable Engineering. This is done before the establishment of a project to avoid redesigning. It is important to note that research and funding for industrial projects have to sync with the principles of Sustainable Engineering. In keeping with the formulation of principles related to Sustainable Engineering, it is applicable to strengthen them with that of environmental, social, and economic values. This will help in creating a safer space for all qualities of life as it provides security toward an imperishable environment.
