For example, ships that navigate United States water regions are subject to compliance to strict engine emission standards, as specified by state and federal agencies, such as state agencies and the federal environmental protection agency (EPA). As ships navigate through international waters to other countries, emission regulations often vary from one country to another. Thus, ship personnel have to keep track of engine emissions of their navigating ship frequently, as the ship moves in and out of regulated regions.
