Eurostar generates ten times less CO2 than flying the same routes

Taking into account the CO2 generated during manufacture of the rails, boring
the tunnels and other mundane things that are for some reason are excluded?

The amount of CO2 generated flying the same route is insignificant.


Manufacturing the rails and boring the tunnels is done once. The CO2
from flying versus rail is repeated thousands of times. Rail still
comes out as far less polluting.
