Emissions to air

Wallenius Wilhelmsen Logistics business activities contribute to air emissions both from the vessels we operate and from our land-based operations. We constantly work to reduce fuel consumption, which contributes directly to emissions reductions of carbon dioxide and to overall reductions in sulphur oxides and nitrogen oxides.

Emissions to water

Wallenius Wilhelmsen Logistics business activities produce emissions to water both at sea as well as on land. Emissions to water at sea are primarily those from discharge of treated ballast water and bilge water from vessels.

Ballast water. In 2008, two new vessels were equipped with an IMO-approved chemical-free ballast water treatment systems, bringing the total number of vessels with such equipped installed to three.

Bilge water. Sixty-six per cent of the vessels that WWL operates met the companys environmental objective of discharge containing 5 ppm or less oil in bilge water. The IMO requirement for oil in bilge water is 15 ppm.

Chemicals. To prevent emissions of harmful substances to water, WWL operates vessels that use an approved list of chemicals on board. This list is continuously updated as more environmentally friendly solutions and products become available.

Biodegradable oil. Fourteen per cent of WWL-operated vessels now use biodegradable oil in the ship hydraulic systems. Fifty-three per cent of the vessels use biodegradable oil in the stern tubes. Biodegradable oils will be used in all new vessels, and as replacement oils for existing vessels.

Emissions to water on land are primarily from runoff at terminals and technical service centres and from oil spills and other leakages of the trucks. No major spills were reported in 2008.
