The ports imposed a fee of $35 (growing to as much a $200 over time) on each shipping container that came into the ports. Considering the value of goods in each container, the cost was a fraction of a penny per t-shirt or a few pennies on a flat screen TV, bicycle, BBQ or any of the thousands of other products imported through the ports. But collectively, on more than fourteen million containers a year, the fund grew enough to make all of those improvements very quickly and slash air pollution (and greenhouse gases that come out of the same sources) by more than 80 percent in five years. Residents cheered and virtually no one noticed the added cost.
