Apologies to all for off topic rant but on this point I must highlight the fact that every year 300 oil tanker accidents occur within European waters, causing between 240,000 and 960,000 tons of hydrocarbons to be dumped in the sea.

Even though the Mediterranean alone boasts 50 waste reception centres, only 15 of these actually comply with minimum requirements

In the EU, only Germany and Greece have ever complied with the incorporation of an EU Directive for waste treatment in ports and to prevent dumping at sea

Every year 300 oil tanker accidents occur within the EU, causing between 240,000 and 960,000 tons of hydrocarbons to be dumped in the sea.

BUT....Illegal dumping and routine operations of vessels within EU waters account for between 666,000 and over 2.5 million tons of hydrocarbons of marine pollution per year.
Nearly 280,000 come from fuel and oil from vessels which are not even oil tankers.
