Climate change is a great risk for the planet and initiatives are happening to mitigate this. SGRE is working towards minimising its climate impacts through a digital innovation event with its employees. The purpose of this report is to make an event system for SGRE to enable ideas to minimise or mitigate their environmental impacts. The system is based on interviews with employees from SGRE and literature on innovation, digitalisation and event management. The system is called “Sustainable Innovation Event structure” and it consists of two aspects: The overall event, which defines the scope and the performed workshops which generate ideas to handle the environmental issues. There are four classifications for environmental issues structures: 1)strict structure, for the local and specific issues, 2)moderate structure, for the local issues with aspects of uncertainties, 3)mild structure, for the global issues with local context and lastly4) Lenient structure for the global wicked problems. Each structure has a predetermined workshop structure, which enables innovative idea creation to mitigate environmental issues. Based on uncertainties regarding implementation, lack of a test run and others, it can be argued that restructuring of the system can occur. It can be concluded that the system can aid SGRE in achieving their goals, after implementation and potential modifications.
