The recession has caused many business a lot of trouble, but not everyone suffers. Jutland-based North Securities proves this case and is currently experiencing a large boom. It had been trying for a long time to sell its fleet management system, Falck Sirius, which enables trucks and buses to cover more kilometres per litre of fuel and reduces CO2 emissions. But that proved almost impossible. The crisis has hit the transport compenies, which now need to pay much more attention to fuel cost. Recently, customers are standing in line to by the fleet management system. Karsten W. Hjorth, director and co-owner of North Securities: "Before the financial crisis, no one focused on fuel savings. Now it is attracting huge attention. We are in a situation where we are having to put orders on hold. We simply cannot keep up." One of the most prominent clients is Arriva, Europe's largest public transport company. Arrive has ordered Falck Sirius for approximately 2,300 vehicles. A test with the system indicated the potential for a 10 percent fuel saving.
