"It's dissapointing that they've failed, yet again, to establish an international guidepost for emissions. It could have opened up for future CO2 efforts," says vice president of the Danish Shipowners' Association, Jan Fritz Hansen, following the recent climate debates in Doha.

The shipowners' association has, like shipowners across the world, been calling for specific requirements regarding CO2 emissions for the shipping industry, but no new decisions were made in this regard at the COP18 summit, which is too bad, says Jan Fritz Hansen, as it could place shipowners in a dumb predicament.
