First of all getting to the match, it's a 25 minute walk from the centre of Manchester with a well lit designated walking route, there are bike racks at the stadium for those choosing to cycle. The stadium has its own metrolink (tram) station for easy access, and although prices have recently increased it's a fairly inexpensive way to travel, we paid £2.80 each return to the park and ride, parking was free. There are also plenty of buses back into the city centre.
The stadium (designed by Arup) was built for the 2002 Commonwealth Games and converted to a football ground the following year. Anyway, there are all manner of nods to sustainability.
This tube and drain are part of the rainwater harvesting system (and as we know, Manchester is no stranger to rain!), all water collected is reused around the campus (the stadium itself and the academy next door). There are also air source heat pumps and lighting is now LED. If you're interested there's more to read about it in this article. There is even talk of generating energy too see here . My suggestion would be to use the labour of people climbing the steps up the their seats, we were up on the top tier.
I didn't really start thinking about this until we got inside (or I would have done more research) but I noticed something written on the side of the drinking glasses
And those all important bins to make waste disposal a little bit easier. It was great to see so many little things in place, obviously it's easier for a new stadium to implement this kind of scheme but it was great to see it, even though most people would never ever notice.
