The Finnish Environment Institute (SYKE) (Finnish: Suomen ympäristökeskus, Swedish: Finlands miljöcentral) is a research institute and government agency under the Ministry of the Environment, located in Helsinki, Finland. It is both a research institute, and a centre for environmental expertise. SYKE's research focuses on changes in the environment, and seeks ways to control these changes.

We provide information and services for political decision-making, sustainable business activities, and for research partners. For citizens, we offer up-to-date information on the environment, tools for assessing their own environmental footprint and for communicating their observations, for example, through these online services: Lake and sea wiki, Baltic Sea calculator, Climate Diet ja Climate Guide.
