IMO debates options to cut ship air pollution

Working group considers marine fuel switch, NOx cuts from existing engines

An international working group reviewing air pollution from marine transport has developed "pretty firm ideas" on ways to cut emissions of sulphur oxides (SOx) and nitrogen oxides (NOx) from ships over the next decade. The group, which met in Oslo last week, will present final recommendations to the International maritime organisation (IMO) in July 2007.

On SOx, national delegates appear to have reached agreement to recommend a long-term global cap on the sulphur content of fuel of 0.5 per cent, sources at the meeting told ENDS. The deadline for achieving this may be set at 2015, with a possible intermediate goal of one per cent by 2010.
