I'd be interested to see the carbon footprint of such a project, too. I'm not convinced that the eco-project at FGR is all it's cracked up to be. Not least because it's a nightmare to get to by rail. Forest Green Rovers? More like Forest Greenwashing.
FGR have a stadium they almost never fill. The owner wants to build a stadium next to junction 13 of the M5 with a population of almost 0 within reasonable walking or cycling distance. Even if the stadium is built with wood, it hasn't grown on a tree so the carbon footprint of building the stadium will be huge. The fact that everyone will need to use motorised transport to get there may also create a rather large carbon footprint. Even if the vast majority of fans travel from Nailsworth / Stroud by electric coach (which seems remarkably unlikely; most people will likely drive), again the construction of the coaches has a sizable carbon footprint. In comparison they could stay at the stadium which has already been built which they don't fill, within walking distance of where most of their fans live.
There's also the question of how it is sustainable to move a club somewhere with no local population. Perhaps the idea is that the can become a national club for people who regard themselves as environmentalists, but it will involve all of them using transport to actually get to the ground from all over the country. Much of the transport used probably won't be very green, so it's questionable how environmentally friendly this will be in practice.
The prospective ground would be near the Bristol-Birmingham line, but the chances of a station opening to serve the stadium seem pretty remote.
I may sound bitter because of the last day of the season, but this has been my view for a long time.
Sunderland deservedly beat Wycombe at Wembley to book their place in the Championship. Wycombe are a glorified pub side so that's a good result. Sunderland play decent football and have incredible support.
Off the field that's harsh on Wycombe - there's much to admire and they have grown as a FL club in the right way. On the field that's fair enough - Wycombe have been notorious in their game management in the lower divisions under Ainsworth for many years. Never concede the first goal to them if you can help it - the rest of the game will be painful to watch.
It'll be interesting when they play Derby next season - a lot of lower league fans dislike Wycombe due to their way they play, but the boot will be on the other foot for once.
