The purpose of sustainable engineering is to design infrastructure that equitable serves a population and efficiently uses resources. Sustainable engineering is not necessarily concerned with environmental issues, but can be concerned with issues like transportation and energy.
Environmental engineering is the branch of engineering concerned with the application of scientific and engineering principles for protection of human populations from the effects of adverse environmental factors; protection of environments, both local and global, from potentially deleterious effects of natural and human activities; and improvement of environmental quality. Environmental engineering can also be described as a branch of applied science and technology that addresses the issues of energy preservation, protection of assets and control of waste from human and animal activities.
