A final aspect that we can consider, trying to understand the environmental impact of a sport, is the required equipment. If we compare sports such as running, where all you need is a pair of shoes and some clothes to practice it, to the formula 1 obviously there is no story. But there are less obvious factors to consider. Instead of running we might think of hiking, where we would need clothing to protect us from the elements, probably made in GoreTex. Unfortunately, the waterproofing of these fabrics is provided by perfluoroalkyl substances (PFAS), which are highly polluting and also called “the forever chemical” because of their long half-life . Currently, neither Patagonia, a famous environmentally conscious sportswear brand, is managing to go without PFASs, but has set a goal to stop using them from 2024 . Finally, a recent investigation by Le Monde has raised the issue related to these pollutants, which you can see that are widely spread in waterways throughout Europe via the interactive map available on their website .
