So, for our implementation, we are working on the re-usable water bottle for IES students. Every day, people buy plastic water bottles and use them and then throw them out. It would be SO much easier if IES had provided us with a water bottle in the beginning. Before coming to Barcelona, I didn't even think about packing a water bottle. I definitely would've packed it if I had known otherwise. In the tuition, IES needs to include an extra little small fee for a water bottle. Our thinking was that the students would have to deliberately uncheck the box if they didn't want the water bottle. I don't know why they wouldn't because for one, it's more sustainable. Secondly, it's a lot less expensive than having to buy a plastic water bottle each day for four months. That can truly add up.
