In September 2005, the city of Los Angeles announced a mandate to cut the air pollution from its harbor. The head of the city's harbor commission, S. David Freeman, gave the port managers a sobering directive: "Start acting like our lives are depending on it," he told them, according to the 29 September 2005 Los Angeles Times, "because our lives do depend on it." Three months later, the California Air Resources Board adopted rules that require ships within 24 miles of the state's coast to reduce diesel emissions to 2001 levels within the next four years. These developments have shippers scrambling to find a way to cut emissions. One of the main technologies attracting their attention is the use of fuel cells.
