Description: When comparing air emissions from different domestic (internal) transport means, road is by far the largest source of such emissions. In 2004, CO2 emissions from road transport in Europe were more than 20 times those from rail and domestic air transport together (data on emissions from international flights are not available). The use of less polluting renewable energy sources - such as solar, wind, hydropower or biomass - depends on their immediate availability/generation, and therefore their consumption cannot exceed production. Fossil fuels such as petroleum are the result of geological processes that took place over millions of years. However, they are being exhausted relatively quickly and are not renewable. At the same time, their use is increasing noxious air emissions. Particular care should be taken to maintain and develop environmentally-friendly infrastructures, keeping in mind their environmental performances to reduce our dependency on fossil fuels
