Sulphur policy as of 2016
As society is learning more about sulphur and it's effects, the impact on human health, particularly respiratory and cardiac diseases, has come to the fore.
WWL has operated with a volountary 1.5 per cent sulphur limit at sea for over a decade, and regualtion is now starting to catch up. In 2015, January 1st, the 0.1 per cent sulphur limit was introduced in Emission Control Areas (ECAs) covering North America and Europe. In 2020 a global sulphur cap of 0.5 per cent will be introduced in 2020. These effectively render our 1.5 per cent policy obsolete.
In line with current scientific knowledge, WWL has decided to contiue its work against sulphur’s negative impact on humans and the environment in a new way. As of 1 March 2016, we have introduced a new policy limiting sulphur content in fuel at berth to <0.1 per cent in all ports across the globe. We achieve this by shifting to MGO or using scrubbers.
NOx emissions objective for 2020
Our new objective to cut NOx emissions by 20 per cent at berth by 2020 versus 2015 (in tonnes per vessel per year) addresses the increased knowledge of the health impact of NOx and particles.
We will implement the new NOx objective by reducing turnaround time in port, renewing our fleet and introducing energy efficiency and NOx-reducing technology in our existing fleet.
Invasive species policies – hull fouling
The spread of invasive species through ballast water is a recognised environmental threat. In addition to transfer through ballast water, organisms can be transferred as fouling on the hulls of ships, and they risk being released during traditional hull cleaning. In addition, hull fouling increases the friction as the vessel moves through water, increasing fuel consumption and hence CO2 emissions.
In 2016, WWL starts implementing the “clean and capture” technology across our fleet, leveraging fully an initial installation of this innovative new technology in Southampton. Through this installation we can cover 95 per cent of our fleet. In addition, we are looking into our dry docking routines. We aim for full fleet coverage by 2018.
New objective for CO2 emissions
Since 2005, we have reduced CO2 per unit transported by about 20 per cent (2017).Our new objective is to reduce CO2 emissions by 10 per cent by 2020 versus 2015, in grams per tonne-kilometre. With a shorter timeframe we create urgency and focus in reducing our emissions in our daily operations and through technical development. We continue working towards our zero-emission Orcelle vision, embarking on an Orcelle sustainable ocean transport project to set direction for our work over the coming years.
