This Green Football Field diagram depicts green stadiums, also known as 'eco-friendly' stadiums, with a significantly lower environmental impact than traditional sports stadiums. Of course, this is good for the planet's overall future, whether we think about it in terms of this generation or the next. Sure, it's a touchy subject, but it's clearly at the heart of the changes made at some of the more environmentally friendly football stadiums we'll see in 2021. If we're being honest, we all love those massive stadiums with massive capacity capacities and the other premium features that come with them.
