TREATISE began by developing reference manuals and training materials on three subjects: Cleaner fuels & vehicles; Ecodriving; and Mobility Management. The project also developed complimentary web-based training tools including an ecodriving simulator, a fleet management tool and a transport CO2 calculator to encourage people to choose lower carbon modes of transport. These manuals and tools have proved extremely popular and can be downloaded or ordered from www.treatise.eu.com The project ran 63 training workshops across eight countries and trained 1 722 trainees (against targets of 20 workshops and 1200 trainees). TREATISE also far exceeded its targets for initiating 20 local transport projects: as TREATISE ended, 41 projects were complete or under way and a further 50 projects were planned including: a pure plant oil fleet trial in Austria; an ecodriving campaign with 500 fleet drivers in France; a joint initiative with the Greek National Gas Company to assess the viability of natural gas vehicles in Athens, to encourage more favourable regulation and to establish pilot CNG refuelling stations; an ecodriving and cleaner fuels&vehicles telephone advice service in UK.
