Wembley is one of the older arenas hosting Euro 2020 matches. Can a legacy venue reduce its environmental impact as well as a newer one? When it comes to legacy stadiums, it doesn’t get more storied than London’s Wembley Arena. Opened as the Empire Pool in 1934 for the British Empire Games, 90 years later it is perhaps the UK’s most famous venue for sports and concerts. In the late 70s it was granted protected status and renamed Wembley, the area of London where it’s located. The down side of that legendary status, of course, is that the building isn’t as energy efficient as newer stadiums. Nevertheless, the arena has made big strides in improving its environmental performance. In 2019 it was awarded the ISO 20121 certificate, the highest international standard of sustainability in events, and was recertified in 2020.
