This year’s theme is “Let’s make it happen!” The Mistra REES programme has been running for three years, during which many interesting activities have been carried out and useful results achieved. The objective of this annual Mistra REES meeting is, besides sharing and discussing results and facilitating a dialogue, also to look forward – and discuss a four-year-extension of the Mistra REES program: Mistra REES 2. Our meeting will take place at Ericsson premises in Stockholm.
