In this blog, I will cover the externality analysis of various transportation choices and related infrastructure. Specifically, I delve into the externalities of road cargo hauling as well as railway transportation. The scope of this series of blogs does not only include the United Kingdom, but also China, the US, and other countries where smart (and not-so-smart) transportation choices have been made, are being made, and will be made.

Transportation has always been the most tangible source of green house gas as people interact with and participate in the transportation system on a daily basis. It is our common sense that vehicle exhaust gas can be poisonous while also being potent green house gas, and that electric subway trains are cleaner than ground vehicles. Yet the transportation sector also produces externalities that are not exactly tangible. It is unlikely that we feel the negative impact of de-icing salt immediately, or see the contrail clouds when we take airplanes. This blog will explain why these intangible externalities matter almost the same (if not more), and how we can deal with them.

So stay tuned and check back often!
