Transportation Fuel Markets

Road transportation is the largest fuel market accounting for 65% of all the fuel consumed by transportation. Even if the marine and aviation fuel markets are comparatively smaller, their importance in supporting global trade should not be underestimated. While there are many alternatives for road transportation over short distances (rail, public transit, cycling), there are very few, if any, for long distance air and maritime transportation. Additionally, each transportation sector tends to use a specific fuel quality, which is linked to its performance, as well as a level of dependency.
