A number of hi-tech innovations that support emission-reduction goals have already been developed by Finnish engineers .
gas emissions from international shipping . For one thing , sulphur content in shipping fuels is limited to less than 0.5 percent .
As to operational measures , reduction of speed and route optimisation would reduce fuel consumption considerably . By reducing average speeds by 12 percent , daily fuel consumption could be decreased by some 27 percent . Weatherbased route optimisation in shipping can result in further fuel savings of some 3 percent .
Technical measures can also reduce emissions . Possible solutions include propeller optimisation , heat recovery systems , hull designs , and emission filtering .
LNG-FUELLED CRUISE SHIPS
Coal-free powering of vessels is one solution . Innovations in battery technologies are gradually paving way for electrically powered ships , at least for short-range routes . Wind-assist systems are also possible and are already in use aboard some cruise ships .
