Why depart from a port that's close to home
You can decrease your carbon emissions by not flying to meet your ship (or at least by flying nonstop). Newer ports in Brooklyn and Mobile, Alabama, are making this easier. Also, flexible itineraries allow you to choose your departure city from among several ports of call. Residential ship the World lets you board in Charleston, South Carolina, Fort Lauderdale, or Anchorage, as long as you’re willing to spend a minimum of six nights on board. Search by departure city at cruisecritic.com (or call your travel agent).
