Emission laws
Ship engines produce harmful nitrogen oxides during combustion. These emissions from maritime shipping have serious consequences for human health. For this reason, strict national and international legal requirements must be observed. The NOx limits are being reduced step by step by the IMO. These limits apply in the so-called ECA (Emission Control Area) zones. There are already plans to expand the zones. In Norwegian waters, a tax on NOx emissions is due. The NOx Fund (www.nho.no) raises a tax and finances the installation and operation of measures to reduce emissions.
