Public transport
Transport has a large environmental impact. People use cars more, especially in urban areas and this
is one of the largest growing sources of carbon dioxide in the world. Private transport contributes to
air pollution and global warming, and taking flights is also a big problem. As more and more people fly,
greenhouse gases increase. In fact, emissions from aviation in Europe increased by 87% between
1990 and 2006.
By using public transport (buses, trains, metros) or cycling in cities emissions from urban transport
could be cut by more than 50%. Using trains for longer journeys as an alternative to flying reduces the
environmental impact often by as much as 90%, and for some journeys is just as quick.
