Sustainable development requires sustainable mobility. Empa investigates mobilitybased fluxes of pollutants in the exhaust as well as in the free atmosphere, and develops methods to reduce these fluxes. This is our contribution to the reduction of the pollution of the atmospheric boundary layer as well as of the emission of greenhouse gases. A central topic is the internal combustion engine, its exhaust emissions and the technical means for their reduction. Powerful analytical tools combined with models and engineering know-how open the way to new solutions. |
