Environmental Costs of the Jones Act
The Jones Act results in using transportation services that pose a greater threat to the environment than shipping.
From the study:
An often overlooked aspect of the Jones Act is its environmental effects. By raising the cost of waterborne transportation, the law encourages the use of alternative forms of transport such as trucks and rail. These alternative means of moving goods generate more greenhouse gases and emit pollutants that are in many ways more harmful than those emitted by waterborne transport. Moreover, the Jones Act encourages the use of older, less-efficient vessels. Thus, the Jones Act contributes to an environment that is more despoiled than would otherwise be the case in the law’s absence.
