One quick tip that we will do this vacation to help reduce our carbon foot print:  we will pack light.  When flying, each additional 10 pounds per traveler requires an added 350 million gallons of jet fuel per year.    I always tend to over pack, and not use several items that I take with me anyways.  This year we will audit what we normally bring and ask ourselves. “do we really need this?”  We will bring  smaller sized things, like toothpaste, shampoo and soaps (ones that we have gotten free from hotels anyways).  Since we will only bring one bag between the two of us, we will have less baggage charges and it will require less time for the ticket counter to process us.  It’s a win-win situation.  Feel free to leave us any of your own experiences traveling lighter.
