Also possibly Eurostar trains have higher average occupancy than normal National Rail.

High speed trains will therefore be using more energy than low speed ones, all other things being equal. But that's not how it appears in your table.<br /><br />Could it be the low carbon score for Eurostar is because French electricity is mostly nuclear and therefore hasMark Brinkleyhttps://www.blogger.com/profile/03473684038478246288noreply@blogger.comtag:blogger.com,1999:blog-7825957372675897778.post-55914046629325348802015-01-22T04:53:52.385-08:002015-01-22T04:53:52.385-08:00Yes they do include RF - it seems to about double ...Yes they do include RF - it seems to about double the numbers, as you say.Nicolahttps://www.blogger.com/profile/09162244617407392907noreply@blogger.comtag:blogger.com,1999:blog-7825957372675897778.post-90503724835453920332015-01-22T04:21:43.703-08:002015-01-22T04:21:43.703-08:00It's good to see updated figures all in the sa...It's good to see updated figures all in the same place - thanks. Do the air travel emissions include 'radiative forcing'? I believe understanding on this has changed, and we should now assume that emissions at high altitude have around double the global warming potential of emissions at sea level.Anonymoushttps://www.blogger.com/profile/07765877732205811470noreply@blogger.com
