Major rail, air and other transport companies have joined EU Commissioners Neelie Kroes and Sim Kallas in a year long campaign to make people travelling in the EU aware of 112 - Europe's single emergency number. Whether for skiing holidays, family days out and about, work-related trips or visits to this summer's sporting events including the London Olympics or Euro 2012 UEFA football championship in Poland and Ukraine, hundreds of thousands tourists and visitors will travel across Europe this year, and need to be informed about this life-saving number. According to the latest Eurobarometer survey, only 26 % of Europeans know that they can dial just three digits – 112 – anytime anywhere in Europe, to get immediate help from local police, ambulance or fire brigade services.
