Unobtainable targets

Impossible and unobtainable targets have been set for the shipping industry, in order to reduce greenhouse gases on the waves, according to a University of Greenwich at Medway lecturer.

Marine fuel oils are responsible for moving the world’s maritime fleet. In an attempt to make shipping more environmentally-friendly, the International Maritime Organisation (IMO) introduced a 4.5 per cent global cap on sulphur emissions - a major cause of acid rain - in marine fuel.

This was taken a stage further by the European Union which insisted that sulphur emission control areas (SECA) be set up in parts of the continent such as the North Sea and the Baltic Sea, where levels would have to be 1.5 per cent or lower.

However, Dr Alec Coutroubis, a principal lecturer in the School of Engineering, believes these targets are unobtainable.

'Not all refineries have the capacity to provide the right fuel in the right quantity and concentration, therefore not enough of the more environmentally friendly fuel is available at all ports of the world,' he said.
