Damco, Copenhagen, Denmark, now provides customers with an online calculation of the carbon dioxide emissions from ocean and air shipment.

The information is available at “myDamco” on the company website, http://www.damco.com/, according to a company news release.

Customers can measure every shipment individually, or form an overview, like of the most emitting categories of shipments, separated by mode of transportation, origin and destination.

Erling Johns Nielsen, the company’s head of supply chain development, said in the release that “greening” a supply chain can reduce logistics costs and emissions by as much as 15%.
