In France, in 2020, 99.4% of the running coaches have a diesel engine. The establishment of Low Emission Zones (LEZ) is accelerating to improve air quality. As a result, a large number of diesel vehicles are being affected by these limitations. Today, passenger transport companies are looking for solutions to continue their transport activity in LEZs, at a reasonable cost because of the fragile economic context.
ECOl’car is a pragmatic retrofit solution for Diesel coaches to run on bioNGV. The operation is entirely carried out locally, thus encouraging circular economy.
