We are already familiar with most of the basic facts: climate change is happening. Our energy resources are getting scarcer by the day, the planet’s biodiversity is suffering and our green gas emissions are at an all time high. It is time we change the way we are treating our planet. We believe that the university, an institution that has both a societal and an educational function, should be one of the leaders in the field of sustainability. And although most of the scientific facts are well known amongst the students and staff of the university, the full potential of our university has not been reached when it comes to going green. By going to university we obtain knowledge and skills that we will carry with us throughout our lives. It is therefore absolutely necessary for Leiden’s highest educational institute to be the primary example in leading the way to creating a young sustainability minded generation.
