Transportation as a whole generates almost one-fourth of global CO2 emissions, compared with scarcely 7% for public transportation. Using its Environmental Management System (EMS), which has been deployed in 889 transportation systems in 24 countries since 2001, Veolia Transport can make very precise measurements of the impact of its activities and its environmental risk management. Cross-checking all the data obtained through this system helps us analyze our performance and set optimal targets.
It also gives us tangible arguments with which to incite public authorities to develop their public transportation systems and encourage the general public to use them. A private car making the same trip will emit 2.5 times more greenhouse gases (GHGs) than public transportation. Raising environmental awareness is, however, only the "green" aspect of a much more comprehensive approach. Passenger safety and quality of service—be it comfort, on-time performance, innovation or information—are just as important.
