EQUALITY

The availability of quali? ed males is failing to meet the personnel needs of the maritime sector. More women are being attracted to maritime careers. This is an excellent development but will require some cultural adjustment for many men. Get over it! Women are just as capable as men and ask only for proper training and equal opportunity for themselves and attitude adjustment on the part of their male counterparts.

Now the focus is shifting to short routes, such as ferries. Increasing pressure to reduce air greenhouse gas (GHG) emissions, particularly carbon dioxide emissions will continue, but the concept of zero emissions is (CO2). Currently, the emphasis in the shipping sector is on ef? - a myth. ciency measurement and goal setting.
