Transport is at the centre of our economy. Mobility is a prerequisite for growth. The transport sector is also very thirsty for energy, using mainly oil to propel itself. Today, the European transport sector is 95% reliant on oil, most of which is imported from outside the EU. This is expensive. In 2014, the 28 member states spent more than €270 billion on foreign crude – the combined GDP of Bulgaria, Hungary, Slovakia, and Slovenia. It also comes at an environmental cost. The transport sector accounts for almost one quarter of the EU’s total greenhouse gas (GHG) emissions. Road transport specifically represents 80% of all transport emissions.
