Starting in 2015 regulations that require ships to produce less locally harmful pollutants (sulphur oxide (SOx), nitrogen oxide (NOx) will be made stricter. This means that ships will have to either switch to different, cleaner fuels or have abatement systems installed. These systems will extract any harmful emissions. The Shipping world is fast becoming a more complex place. New technologies and innovation play a vital role in the immediate and long-term future of shipping. New fuels, new designs and new engines are now becoming available. Any evolution will be gradual but already we can see changes happening. Most of the new technology that is being brought into operation has been developed for relatively small or niche markets (ferries and inland waterways).
