A new ticket initiative from Deutsche Bahn will allow the IMEX trade show, to be held in Frankfurt on 24-26 May 2011, to provide carbon-free train travel to all of its European hosted buyers in 2011.

The tickets, labelled Umwelt-Plus, will be available to all hosted buyers travelling to the Frankfurt trade show from continental Europe.

IMEX said the ticket guarantees that Deutsche Bahn will only use renewable energy for all hosted buyer rail tickets.

Unlike compensatory measures, the tickets avoid carbon dioxide emissions since the electricity used is produced exclusively from renewable energy sources in Germany.

DB purchases the amount of renewable energy required for journeys in advance where the additional energy replaces the energy from other sources in the rail power grid.

Once the show is over, IMEX will receive a certificate showing the total carbon dioxide saving made as a result of the green tickets.
