Are trains really Green?

According to Roger Kemp of Lancaster University, trains produce as many greenhouse gases on a per-seat basis as cars and planes. Standard high-speed trains in the UK are no better than modern economical cars - and the new superfast trains are as bad as planes over 600km.

However, suburban trains and metros are much more efficient than cars, mainly due to higher passenger density, but also due to getting from A to B much more quickly than cars that are stopping and starting all the time, using more fuel in the process.
