Air pollutant emissions


The research aims at developing tools and methods to evaluate air pollutant emissions, more specifically from road transport. Methods are proposed to detect errors in emission inventories. The research is conducted to be transferred as soon as possible to any territory in the world.

Research objectives

  • To assess pollutant emissions and validate the inventories

  • Develop strategies for reducing pollutant emissions

  • Define air pollution reduction strategies
