In the context of its power generation and transmission projects, Hydro-Québec has carried out environmental impact studies for many years. The company has developed expertise in environmental matters that is now used in the design of new projects. Here are two summaries of knowledge acquired over the past 40 years with regard to the natural environment and the human environment.
