The table illustrates the amount of CO₂ emissions produced by different forms of transport in the European Union, measured in grams per passenger kilometre. The pie chart shows how European Union funds are distributed among various transport sectors.
Overall, air transport produces by far the highest level of carbon dioxide emissions, while coaches generate the lowest. In terms of funding, the majority of EU transport investment is allocated to roads, whereas other sectors receive relatively small proportions.
Looking first at CO₂ emissions, air travel is responsible for approximately 370 grams per passenger kilometre, making it the most polluting form of transport. Passenger cars also emit a significant amount, at around 120 grams. Buses produce a lower figure of roughly 70 grams, while rail and maritime transport emit similar amounts, at about 40-50 grams. Coaches are the least harmful to the environment, releasing only around 30 grams of CO₂.
Turning to EU transport funding, roads account for the largest share at 52%, followed by railways at 31%. Public transport receives 10% of the total budget. By contrast, very small proportions are allocated to airports, inland waterways and intermodal transport, each accounting for only 1-2% of overall funding.
