April 22, 2020 marks 50 years of Earth Day. Amid the current crisis, it is more important than ever to protect our natural environment, as intact ecosystem are crucial for clean air, water and food supply or disease control and thus healthy and resilient societies. At SSE we have continuously increased the faculty of sustainability researchers, and dedicate courses in all our programs to topics like environmental economics and how businesses can respond to climate change and other sustainable development goals (SDGs).
