The NOx requirements for ships' emissions were debated heavily at the IMO's meeting of the environmental committee MEPC last week. The meeting resulted in a decision to postpone the requirements from 2016 to 2021. The decision will be finalized if 2/3 of the countries vote in favor of the proposal at the next meeting of the MEPC, in March 2014. The decision will impact engine suppliers such as MAN Diesel & Turbo, where CEO in Denmark, Thomas S. Knudsen, is disappointed by the changes.
"We've invested a lot of money in Tier III technology, so it's a shame we won't get a chance to use that technology. A big part of our development efforts have been aimed at being ready for the requirements by 2016, which have now been changed, " he says, referring to the Tier III requirements established internationally in regards to engine emissions.
