Impact of transportation on environment

Our aim in this article is to prove the connection of CO2 emission and climate change and to estimate the CO2 emission of the transport sector. We have to clarify the emission of the transport sector in order to get information of externalities, what is a further step to a sustainable society. The sustainable development is a development, where the pace of technical development, the satisfaction of increasing supply and the raw materials and resources of Earth are poised so that the rate of living and opportunities of the next generations need not to be worse. One of the most emphasized goals of the transport policy of the European Union is sustainable mobility. For this reason transportation systems must be developed and standardized, the effectiveness of transportation service must be increased, while the environmental pollution must be decreased or prevented. Decoupling motorization from environmental pollution is the task for engineers. Decoupling the increase of mobility from economic activity is a tas k for economists
