The bar chart provides information on how different means of transport emit CO2 in European Union, while the pie chart depicts the proportion of the investment made on the various kinds of transport.
Overall, it is clear that air is dominantly polluting per passenger-kilometre in the bar chart, while it makes up the minority of European Union funding.
Turning to the details, as stated by bar chart, air travel was the mean of transport with the highest CO2 emissions, at around 380 grams of CO2 per passenger-kilometre. It is nearly three times higher than the second highest emmision is passenger cars, which is followed by buses with approximately 70 grams, while the figure of maritime traffic was identical to the rail transport, at nearly 50 grams. The lowest of list is the coaches, emiting just under 40 grams of CO2 per passenger-kilometre.
Moving onto EU funding, there were two main sectors dominated the fund: roads and railways. However, roads accounted for 52% of the total investment, railways followed with the almost one third. Next place was public transport, which is approximately three times lower than the second place. In contrast, Intermodal, Inland waterway, Ports, Airports and unknown each received a small proportion roughly 1-2% of the expenditure.
