The given bar chart illustrates the carbon footprint of distinct modes of transport in Europe, while the pie chart compares the proportion of EU funding on different means of transport. Overall, in the bar chart, air is the primary polluting per passenger-kilometre, while roads take up the majority of EU funding.
Turning to the details, as regards the bar chart, air travel was the form of transport with the highest CO2 emissions, at around 380 grams of CO2 per passenger-kilometre. This figure was nearly three times higher than the second most polluting mode, which is passenger cars, with about 130 grams of CO2. In third place was buses, at approximately 70 grams, while the figure of maritime traffic was as high as that of rail transport, at nearly 50 grams. Bottom of list was the coaches emit with just under 40 grams of CO2 per passenger-kilometre.
WIth respect to the distribution of EU funding in the pie chart, there were two main sectors dominated the fund: roads and railways. Meanwhile, roads accounted for 52% of the total budget, railways followed nearly, at 31%. Next place was public transport, which was approximately three times lower than the second place, at solely 10%. In contrast, Intermodal, Inland waterway, Ports, Airports and unknown each received a small proportion at around 1%-2% of the budget.
