Transporte y calidad del aire en Madrid. Resultados de las mejoras de la tecnología de los vehículos y de los combustibles en la atmósfera del municipio de Madrid

Abstract

This paper shows that the concentrations of sulfur dioxide and carbon monoxide have decreased due to the increment of the quality of fuels and more preventive vehicle emission standards developed during the study period. However, the concentrations of nitrogen oxides, particle matter and ozone have been kept despite the improvement of the unit vehicle emissions, due to the increment of transport mobility. Therefore, the concentrations of nitrogen oxides and particle matter are above the emission standards allowed.
