It's a buzzword that comes up a lot in food, transport, energy, and other industries. Laura and Antonia discuss what sustainability means and why its not so easy to decide whether something really is sustainable. Although some aspects of sustainability can be measured, others are more of a philosophy which depend on the society and environment you're working in. The team digs into a real-life example that compares digital books to printed ones to illustrate how challenging it is to demonstrate sustainability.
