Sonja Leinonen

I advise our clients in matters related to the environment, infrastructure and natural resources as well as industrial projects and energy law assignments.

Initially I joined Castrén & Snellman as a trainee. Prior to graduating, I also worked at another major law firm on questions related to energy law and wind power and in the Unit for Sustainable Development and Climate Policy of the Ministry for Foreign Affairs of Finland.

I graduated from the University of Helsinki where I wrote my master’s thesis on the international regulation of underwater noise caused by shipping.
