The Eco-Efficient Travel TM indicator measures the performance of public transportation in terms of CO2 avoided, atmospheric pollution avoided, private cars avoided on roads, and liters of fuel not consumed, all in comparison with private cars.
The calculation method has been developed since 2006 and patents registered in 42 countries. It is based on emission factors published by official organizations in all of the countries (checked annually by Ernst & Young as part of the EMS reporting procedure). In both Maastricht, Netherlands, and Nice, France, this sustainable mobility indicator helped detect the transit system's environmental weaknesses and correct them. In Barcelona, Spain, we measured the transit system's eco-efficiency and confirmed the value of its environmental performance.
This indicator became an additional argument to justify the installation of a backbone line between the two existing light rail lines. In Dublin, calculations demonstrated that the LUAS light rail system emitted five times less CO2 than private cars traveling the same route.
