The sixth EUROTRAC Symposium was held in Garmisch-Partenkirchen, th st Gennany from 27 - 31 March 2000. Some 375 scientists from 28 different countries (from the USA to Uzbekistan) gathered together and contributed to a lively week. Symposium 2000 was the second Symposium of the second phase, EUROTRAC- 2 which is EUREKA environmental project number 1489, and also the ftrst one organised by the new team at the International Scientiftc Secretariat (ISS). We stayed with the tried and tested EUROTRAC format, giving ample time for poster sessions as well as side meetings and workshops. The invited talks, over 35 in all, contributed breadth and depth. The Symposium had the focal points of "Shaping the Future" and "Scientiftc Research and Environmental Policy". The "Highlights from the Subprojects" were well represented by a series of talks and of course by the ca 300 posters. Guest poster contributions added to the spectrum of scientiftc coverage. An innovation for 2000 is the publication of these Proceedings in a book containing the extended abstracts of the lectures and a companion CD-ROM with the extended abstracts of the posters as well as the lectures. The availability of the Proceedings on a CD will enable us to distribute them more widely.
