Introduction• The USEPA has developed nine green engineering principles which engineers should follow to fully implement green engineering solutions: • •Engineer processes and products holistically, use systems analysis, and integrate environmental impact assessment tools. •Conserve and improve natural ecosystems while protecting human health and well-being. •Use life cycle thinking in all engineering activities. •Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible. •Minimize depletion of natural resources. •Strive to prevent waste. •Develop and apply engineering solutions, while being cognizant of local geography, aspirations and cultures. •Create engineering solutions beyond current or dominant technologies; improve, innovate and invent (technologies) to achieve sustainability. •Actively engage communities and stakeholders in development of engineering solutions.

• To allow the students to develop an understanding of the need to go green
• The website aims to show prospective and current students about the global, environmental issues that engineers encounter daily.
• The website will act as both a portal and as an informative webpage.
• Regarding the portal aspect of the website, the homepage will provide valuable links to direct students to other useful websites where they can learn and immerse themselves in the environmental aspect of engineering.
• The website will function as an informational website, and provide descriptions of how each class here at our CEE program at Rowan University will strive to incorporate environmental issues into the student’s curriculum.
