During the next thirty years it is expected that the total export and import business in the United States will increase by more than two and one-half times. The fastest growing proportion of the industry is refrigerated shipping containers, RSCs, which represent at present 30% of the shipping container traffic, and it very important that the shipping ports in California operate in an economically and environmentally friendly manner. The primary purpose of the present study was to investigate the emissions that are associated with this important and dynamic industry. It is well known that the United States imports more goods than it exports, but California Ports export more food products than are imported. |
