improving energy efciency in ships in 2009 the international maritime Organisation agreed a range of measures to help improve the energy efciency of the global merchant eet.The
eet provides transportation for oil and gas, containers,
people and bulk cargoes such as timber and iron ore. When fully implemented in 2011, these are expected to have far reaching improvements on standards of marine construction and operation.
The measures include:
an energy efciency rating index specically for ships, similar to those used to rate cars and electrical appliances;
a management system for all ships to monitor and reduce cO2 emissions covering route planning, speed control, weather routing, engine optimisation, navigation control, hull maintenance and fuel selection;
possible taxes, emissions trading or other market based mechanisms to be applied globally to the sector; and
global principles for developing regulation on reducing cO2 emissions regardless of the national
ag being own.
implementing the measures WWf hopes that the design and operation indices become mandatory for the entire eet. by having minimum standards applied to all vessels it will have a real impact on the environment and safety levels.
a balance of nancial incentives and penalties will need to be maintained to ensure compliance.The agreements should also be structured to encourage incentives that go beyond efciency savings.
if a nancial mechanism such as a carbon trading scheme were to be introduced it could potentially provide the right stimulus.To work it would need to limit the amount of carbon available to create a demand between participants. each year this amount of carbon would reduce encouraging ships to continue to improve emissions.
if carbon is assigned a cost for shipping it will have less
nancial impact on the more efcient vessels.voyage
optimisation is one way to minimise costs and carbon. by carefully planning routes, avoiding adverse weather conditions and travelling at slower speeds, cost and
carbon savings can be achieved. caution is needed to make sure that engines do not operate below the speeds they were designed for.This could damage them and create a bigger environmental impact.
implementation in a diverse eet cannot be expected overnight. it is likely that it will take ve years for all the measures to come into force. many vessels already operate at efcient standards, enjoying reduced fuel costs and lower insurance premiums.vessels over 25 years old tend to be a higher risk, although a very well maintained 30 year old vessel may actually be in a better condition than a 15 year old one that’s been poorly maintained.

“it’s likely that resale values for vessels could be lower in future because of their carbon footprint. This would have been more signicant if shipping had been included into an emissions agreement in the copenhagen cOp15 talks in 2009.
“a key concern about emissions agreements is that we need to make sure we don’t drive passengers and short sea shipping towards more environmentally damaging forms of travel.These commercial activities use a sustainable form of transport but are cost sensitive and extra carbon penalties may make them too expensive.
“it’s important that all vessels try to adhere to best practice and work together to reduce emissions. by doing this it will help us try to keep below the two degrees of climate change needed to stabilise our environment.”
