Human activity is endangering the sustainability of ecosystems around the world. The Finnish Environment Institute (SYKE) conducts long-term monitoring of the state of the environment and related trends. Using our wide-ranging expertise together with our partners we seek out the best solutions for building a sustainable society. We do this with the help of scientific trials, multidisciplinary scenarios, predictive modelling, and the latest know-how from many fields. We address vital issues by focusing on the big picture.
