Cruising the green seas

Winter doldrums making you crave an escape to sunny ports of call? G Living takes a look at ocean cruises.

The bigger ships often have spotty histories of environmental problems, but some are cleaning up their acts (and we don't mean what's playing in the Lido Lounge either).

Alternative engine technology and lower smokestack emissions are among the steps cruise lines are taking to reduce their carbon footprints. One even offers earth-friendly dry cleaning, so your tux for the formal dinner will look spiffy. Full steam ahead.
