In 2018, 25 % of total EU-27 carbon dioxide (CO2) emissions came from the transport sector (including international aviation) (1). CO2 is the primary greenhouse gas emitted through human activities and a cause of global warming. CO2 emissions from transportation primarily come from vehicles powered by internal combustion engines. Reducing fossil fuel-based vehicles is key if we want to reduce global warming. In the case of freight transport, we would achieve a significant reduction of CO2, if we shifted the road freight to the much more environmentally friendly railway transport mode.
