Ile-de-France Mobilités publishes study on vehicle emissions

POLIS member, Ile-de-France Mobilités (IDFM) has published a study revealing vehicle emissions in Paris.

The study, conducted in partnership with Airparif, examined the impact of engine and traffic conditions on emissions produced by buses the French capital. Launched in the wake of the Dieselgate scandal, the investigation sought to distinguish actual figures from those measured in laboratory conditions, which have been found to underestimate Nitrous Oxide emissions.

Using sensors attacked to 28 diesel, hybrid and compressed natural gas (CNG) buses, the study quantified participate matter, nitrogen oxides (NOx), carbon monoxide and CO2, in a range of locations and varying weather conditions across Paris.

The research comes amidst IDFM’s overhaul of the Paris’ bus fleet. Between 2014 and 2020, more than 2000 vehicles were replaced with less polluting models (Euro VI buses, hybrids, CNG and electric), which were shown to have reduced annual emissions of NOx and CO2.

IDFM aims to completely phase out the use of diesel buses in urban areas by 2025, a major commitment to sustainable mobility!
