What I know about baseball would probably fill the back of postage stamp – ask most Washington National fans to commit their thoughts on sustainability to paper and that same stamp still wouldn’t look overly congested.

However, when those same fans take a stroll into their brand new $311 million stadium on Sunday they can expect to bowled over by a ballpark which is setting new environmental standards.

Sport is often a fairly accurate barometer of the importance a global issue is assuming, and with their energy efficient lighting, low-flush toilets, recycling bins, and reserved parking spaces for high-mileage cars, the Nationals have clearly left their rivals on first base when it comes to lowering their environmental footprint.

Can they play Baseball? You're asking the wrong chap.
