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 knowhow from many fields. We address vital issues by focusing on the big picture.
