GREEN TRANSPORT: WATER TRAVEL

The shipping industry pollutes dramatically more than other modes of transport. It’s in dire need of revival

Over one in ten children are suffering from asthma in the world’s major port cities. Shipping is not regulated and taxed as needed; similar to aviation, since it transports about 90% of all world’s traded goods. Governments in different countries have initiated programs though without major success.

For example, UK proposed a cap-and-trade to encourage companies to follow environment protection guidelines. The World Port Climate Change Declaration conference also emphasised on the importance of greening the shipping industry. Seatrade Middle East Maritime unveiled new innovations in green shipping in 2008. Even companies like Royal Caribbean Cruise Lines are installing smokeless gas-turbine engines or biofuel engines. Many have undertaken research to develop engines to fuel environment friendly CNG and LNG vehicles to avoid harmful emissions like NO2 and SO2. While regulation is imperative, focusing on a few other areas will greatly help.

Primarily, the oil that the ships use is of a very low grade. Technological innovations (use of hydrodynamics in propellers, replacing fossil fuel by renewable sources, and taking care of speed reduction and fleet maintenance) can reduce emissions. But the scale of these initiatives has to be far grander than it is today.
