There are multiple new concepts circulating regarding how we should reduce our carbon footprint and become more frugal in our day-to-day lives. One is called car-sharing which is essentially sharing your car with someone else, ultimately reducing the overall cost of transport for both of them. Car-pooling is a means of transportation when a group of people use the same vehicle when travelling to the same destination. Couch surfing is a method of cheap accommodation where one stays in a friend's or relative's house wherever there is space. House swapping is another way to get free housing during your vacation days where you swap houses with someone else during a set period of time for free, so both parties do not require to pay for accommodation.
