In this paper we consider the causes of environmental problems of large cities, the impact of transport and technological activities on air pollution. The comparative dynamics of changes in the number of cars in Russia and other countries. The approximate component composition of exhaust gases for carburetor and diesel engines and the conditions of formation of the most toxic substances are analyzed. The reasons of the greatest pollution of the atmosphere by activity of transport and technological infrastructure in the Russian Federation in comparison with the Western countries are revealed. The structure of the automobile fleet of the Russian Federation on norms of toxicity. The ways of minimizing the impact of vehicles on the ecology of megacities by improving the quality of fuel and abandoning the no-alternative monopoly on diesel fuel are proposed. The necessity of modern technologies of oil and gas processing, expansion of opportunities of the fuel market of the country, improvement of its quality and environmental friendliness is revealed. Prospects of use of gas motor fuel are defined.

Emergency oil spills during main pipeline transportation have an extremely negative impact on the ecosystem. It is not possible to estimate the effects of oil spills, because oil is a product of long period decay. Oil pollution compromises processes proceeding in the biosphere, changes the living conditions of living organisms and their interrelation. Oil spills need to be prevented for negative impact reduction or, in case of an accident occur, spill need to be stopped and consequences need to be eliminated in a short time. Accident prevention is achieved by observing the requirements and rules of engineering surveys and pipeline design. If the requirements of standards are complied with, the hydrogeological and climatic features of the district are considered during design, construction and operation, the pipeline should work without accidents during the service life. But accidents may occur as a result of human factors, natural calamities and other unexpected circumstances. Oil spill prevention is not simple and not standard task. For time and costs reducing universal tool for oil spill prevention needs to be invented. This tool needs to be used before temporary clamping structure will be installed.
