The current issue of The Maritime Executive has an article dedicated to green sailing.
Perhaps, we first heard about green sailing when we learned that Falls of Clyde International wants to use Falls of Clyde as a teaching ship to further the movement toward shipping with fewer carbon emissions. Well, the movement is toward improving both old ships and new ones -- and it's a very good thing!
Remember how black smoke used to pour from the engines of jet aircraft? Just watch the ill-fated aircraft take off in Jack's movie, The Doomsday Flight (Universal Television,1966) and compare those emissions to those we see coming from today's aircraft.

The same improvement is being sought for ships -- and has been sought for many years. Back in 1958-1960, the Navy handled it by switching from the heavy pollutant, Bunker C fuel oil, to nuclear power with the introduction of its Nimitz-class aircraft carriers. The USS Enterprise (CVN-65) was the first nuclear-powered ship. Today, all US Navy ships are nuclear powered. Now, commercial shipping is looking for ways to reduce the numbers.
