Maritime Executive magazine reports that experts in the shipping industry are concluding a meeting at the headquarters of the International Maritime Organization (IMO) this week tho complete a third greenhouse gas (GHG) inventory for the worldwide shipping industry. The last IMO GHG inventory, published in 2009, reflected the downturn in shipping activity that was a fallout of the global recession. While shipping activity is not at pre-recession levels yet, everyone expects that this GHG inventory will reflect the increased worldwide shipping activity … more overall GHGs.
The shipping industry has done a number of hings to reduce overall GHG emissions:
- using shore power (aka “cold ironing”) while at dock, rather that generating electricity through fuel-burning generators
- switching, where possible, to low-sulfur fuels
- upgrading on-board technologies to take advantage of processes that can reduce fuel burn
- integrating carbon footprinting into route modeling software
- slow-steaming, which can reduce emissions
Mile-for-mile, ton-for-ton, shipping is considerably better than air from a GHG emissions standpoint. We believe that the shipping industry will be well served by completing and publishing its updated inventory, identifying hotspots that demand immediate action and continuing to implement and enforce the 2011 amendments to MARPOL Annex VI.
