The most significant variations are due mainly to the na-
ture of the principal activity of the channels which is infor-
mation.Thus it may be seen that emissions deriving from
rail transport are a consequence of the increase in the
amount of that form of travelling, an increase caused main-

Travelling by air also increased due to the coverage of the
European Football Championship held in 2012 in Poland
