What  comes to mind when one thinks of sustainable mobility? Is it electric  and hydrogen cars, light rail systems and bicycles? If you thought of  these things essentially you would be right, but is that everything?  Does the whole issue of transportation on the journey of sustainable  development boil down to just our dependency on oil and its impacts?
 If we are to achieve sustainability in tourism then the  environment and the issue of climate change are just pieces of the  puzzle. I will attempt to look a little bit on the social and economic  aspects of this issue of mobility. Taking the issue of the  environmental damage out of the picture I will examine two aspects of  sustainable mobility often overlooked.First  I would look at mobility within destinations and then between  destinations.
   In  tourism there is a term called 'multiply effect', which in essence, is how money is circulated through the local economy without any leakages (e.g. money leaving the destination). Having a  high multiply effect is imperative for true economic development and for  the multiply effect of a destination to be high, locals and tourists need to  purchase from local shops and vendors. This helps the local economy by promoting linkages  throughout the economy and encouraging entrepreneurship. Because of this the act of patronizing these shops  should be easy and convenient.  This is where the issue of walk-able cities and destinations come into play. In destinations not conducive to walking and cycling, especially cities, there is vehicular  traffic and parking is always at a premium.  This  has a direct impact on the likelihood of someone randomly going into a  store and purchasing an product or service.  For this reason, destinations in the Caribbean  should try to become as walkable as possible so tourists allowing them to explore the area with ease. In doing so, contribute to the  development of the local economy. Someone who is walking along the  street is more likely to stop and support local business than someone  who is stuck in traffic or searching for a park.
 Another  hindrance to sustainable mobility is that of vertical integration.  Vertical integration in tourism refers to when international tour  companies have links with international airlines and hotel chains. These  tour companies then promote their linkages and most times only recommend their partners to their customers. How does this affect the sustainability of island states? The  answer is that these island states are then not in control of their own  destiny. Neither do they reap all of the economic benefits of the vacations  they facilitate. In other words, a tourist attraction or hotel in the  Caribbean may be at the pinnacle of sustainability charts, yet how its guest arrives at the site may not be sustainable. Research done by  the United Nations Economic Council of Latin America shows that the host  nation only gets 40-45% of the retail cost of the organized holiday  tours. Even if they used local hotels and visit locally own sites. The 55%-60% is lost with the use of foreign  airlines. This percentage drops even further when the tourist utilizes  foreign owned hotels and other foreign owned attractions.
  With foreign airlines taking that much money, it forces us to  look as sustainable mobility beyond just its environmental impacts. The use of  foreign airlines to get to a vacation destination can deny the country of  approximately half of the money they help generate. With this in mind, no matter how  clean air fuel gets, can it really be considered sustainable? The answer  is no. The dependence on international airlines can in some cases  can ruin a country’s tourism product, by deeming that route 'unprofitable'.  However  it is impossible for all island states to have their own national  carrier as they are a drain on national funds. We have seen a perfect example in the case of Air Jamaica.
 I’m  not quite sure how we are going to deal with this issue but I do know  that the current system is not doing small island developing states any  justice. Hopefully though, we can begin to look at this issue from a  wider perspective and help us achieve sustainable tourism.
