As an environmental frontrunner, we believe in setting goals, tracking performance and delivering results. Reducing emissions from our ocean fleet is the single greatest way to improve our environmental performance today. To achieve this we operate our vessels with low sulphur fuel at sea, and invest in advanced technology that improves the fuel efficiency and emissions performance of our fleet.
We also believe in accountability. We use state of the art systems to measure the performance of our fleet, and publicly report the externally verified results.
WWL's objective is to reduce our relative CO2 emissions 30% by 2015 compared to 2005. This is achievable, but is to a large extent dependent on market forces that affect optimal loading of the vessels. Despite improvements in the technical and operational efficiency of the fleet, the 2013 result increased 1.3% on 2012 due to the weak market.
In 2013 the total CO2 emissions of WWL's ocean operations fell by 17% year-on-year to 2 042 000 tonnes. The reduction was primarily a consequence of the relative reduction in cargo volumes.
For the 10th year in a row, we have maintained our 1.5% global fleet average sulphur policy, coming in at 1.49% in 2013.
Cumulative savings in SOx emissions since WWL was established have now exceeded 200,000 tonnes due to our 1,5% low sulphur fuel policy (compared to the industry average).
Average relative NOx emissions in g/kWh Continued on an overall downward trend. Due to an minor error in the calculation of previous years result, which have not been adjusted here, the apparent 1.3% increase on 2012 is not reflected in real terms.
In 2013 WWL's owners placed orders for eight new 'High Efficiency RoRo (HERO)' vessels. With with a wider beam that necessitates less ballast, efficient engines and optimised propellers, the fuel consumption per cargo unit will be approximately 15 per cent lower than in the previous generation of newbuilds.
