Building productive transportation systems can only be accomplished by designing them sustainably. We can’t overcome unavoidable limits on clean air, stable climate, and land by just spending more money. Our new imperative must be moving freight while minimizing its impact on the environment, open space, highway capacity, and the overall costs of building and maintaining infrastructure. Given the differential between trucks and trains in the space they require for moving goods, the environmental impact of their relative fuel usage, and the efficiency of steel versus concrete and asphalt, it is critical that we shift into designing systems that optimize use of these two modes.
The market can only support this if business, government, and community cooperate. This can be accomplished by aligning around whole-system lifecycle measures and sustainable investment strategies.
Considering the pressures of increasing population on land use, transportation congestion, and the environment, three significant evolutions must occur: 1) include shorter supply chain options in planning, 2) ship as much as sensible by rail to benefit from its energy and space efficiency, and 3) proactively think and plan for reduced dependence on fossil fuels. Accomplishing these transformations must include win-win approaches that support existing transportation providers through this transition. Our existing truck, rail, water, and pipeline infrastructure is too vital to strand assets.
