Report: Inland Barge Transportation Best Environmental Choice MarAd Report Cites Studies & Research A report issued by the Mari time Administration (MarAd) concludes that inland barge transportation is a safe, efficient, economical and environmentally sound method to transport prod- ucts, and superior in performance when compared to both rail and truck. Energy Efficiency According to the report, numer- ous studies on fuel efficiency, in- cluding studies sponsored by the U.S. Department of Energy, indi- cate similar results: shallow-draft water transportation is the most fuel efficient mode of transportation for moving bulk raw material, is the least energy intensive method of freight transportation when mov- ing equivalent amounts of cargo, and consumes less energy than al- ternative modes. Specifically, the report quotes two comprehensive studies done by the U.S. Congres- Figure 1 Measures of freight Energy Efficiency (BTUs per net ton/mile) Mode Operating Line-Haul Modal Energy (1) Energy (2) Energy (3) Rail - Overall 660 1,130 1,720 Unit Coal Train 370 590 890 Truck - Average Intercity 2,100 2,800 3,420 Barge - Overall 420 540 990 Upstream 580 700 1,280 Downstream 220 340 620 Note: net ton/miles includes weight of cargo only.

Eastman. The major finding of the CBO study was that inland barges were most efficient in terms of oper- ating energy, line-haul energy and modal energy (see Figure 1 for de- tails). The Eastman study found "barge transportation to be the most fuel efficient method of moving the raw materials and semi-finished products..." The study showed a range of 270 BTUs and 350 BTUs per ton/mile, versus a range of 650 BTUs to 750 BTUs per ton/mile for rail. Another study performed by the RAND Corp. and detailed in the MarAd report determined that, on average, water carriers consume 500 BTUs of energy per ton/mile, the lowest of any mode studied. The next lowest, rail transportation, con- sumed 750 BTUs per ton/mile, and trucks consumed 2,400 BTUs per ton/mile. In real terms — fuel burned — these numbers indicated that water carriers burn about 3.6 gallons of fuel per 1,000 ton/miles of cargo moved. Other studies by in- dependent carriers have shown con- sumption rates reportedly as low as 2.92 and 2.99 gallons on the same basis. Safety Transporting freight of any kind, to any destination, in today's envi- ronmental climate means accepting the responsibility to transport it safely. Several studies have shown that water transport has the fewest number of incidents, fatalities and injuries of any surface mode, accord- ing to the MarAd report.
