Online platforms for collaborative consumption are tools that allow people to share goods or services with one another. They are a way for people to get what they need without buying it and without having to pay someone to do it for them. For example, let's say you need to borrow a lawnmower and some garden tools to work on your garden. You could go to an online collaborative consumption platform and search for people who have these items to loan you. You could reach out to the person and ask if you can borrow their tools for a certain amount of time. This is a way to save money by not having to go out and buy the tools or hiring someone to come and mow your lawn.
