Transition engineering is the professional-engineering discipline that deals with the application of the principles of science to the design, innovation and adaptation of engineered systems that meet the needs of today without compromising the ecological, societal and economic systems on which future generations will depend to meet their own needs. Today safety is an expected consideration in design, operation and end use. Transition Engineering aims for a similar consideration of sustainability. Transition engineering is a trans-disciplinary field that addresses wicked problems while creating opportunities to increase resilience and adaptation through change projects.
