“Sustainability”, “low emissions”, “saving fuel” – these are the buzz words in global shipping circles these days. With jacked up oil prices and pressure on ports to “Green” their operations, ship owners are frantically casting about for new technologies to lower the footprint of their vessels. Basically, the key players are getting innovative  both for the good of the planet and their pocket books too. This was the dominant message coming out of the Baltic and International Maritime Council’s General Meeting held last week in Vancouver.

It was no coincidence that this old boy’s maritime club held its first North American pow wow in green champion Vancouver, whose world class port is gamely singing from the same sustainable song book. For two days,  I sat in on enthused discussion between shippers, demographers, climate change academics and ex-heads of state on how shipping is doing and and where it still needs to go to lower its footprint.   The main consensus was that the economic benefits of going green are irrefutable; the technology is almost there to make it happen; keeping pace with demand, however, is questionable.

Interestingly, shipping is the most efficient form of  transportation on the planet, accounting for over 90 per cent of global goods movement, but just 3% of transportation’s fossil fuel emissions. Local presenters from Teekay, Seaspan, Robert Allan Naval Architects, and BC Ferries championed their efforts to lower these emissions even more through innovation in hull and motor design. The importance of better trained crew to operate more sophisticated vessels and new fuel management challenges were also emphasized.

Expect more of these ships on the horizon, cutting up to 35% in fuel use.

Tall Ships in English Bay, June 7, 2011

Basically, the technology is out there to create a greener world fleet and reduce its carbon emissions by up to 20% in the next decade. But is all this will and know-how a case of too little too late? World population continues to explode creating immense pressure to churn out more ships cheaply and quickly keeping the eye of many shippers on short term necessities rather than long term environmental goals.

Almost in pseudo recognition of the dilemma in which shippers currently find themselves – forced to navigate the contradictory imperatives of growth vs. green – these two beauties sailed unannounced into English Bay last week in stark, sustainable contrast to  the diesel monsters behind them.
