Sustainability has received increased attention across a variety of different disciplines due to a public desire to create less waste and protect the environment. By not considering sustainability, humans are threatening many food sources by depleting them faster than they can naturally replenish and damaging large areas of the environment. Also, health risks such as water contamination and asthma stem from pollution of the environment. These areas demonstrate the importance of sustainability for the overall good of the environment as well as human health and well-being. The study aims to investigate the sustainability of waste management practices for large sporting events. This involves examining what event organizers are currently doing to deal with waste, and how their practices can be improved to both reduce cost and benefit the environment. This will include case studies on a few different sporting events and look at how they approach waste management. These case studies will be assessed for their performance in sustainable waste management using a new metric called the sustainability score. This will allow people to see the current industry practices and how the event industry can improve their practices, which will be useful for event organizers in the sports industry and beyond.
