Heineken - Walk in Fridge

I saw this ad last year on TV, and I thought it was hilarious! I think they show it during the Super Bowl. Unfortunately, I couldn't find it in English, but pretty much the woman says this is the living room, and this is the closet. Although this Heineken ad is very funny, it stereotypes women and men; and at the end, it shows Heineken "serving the planet".

First of all, it bothed me that this ad stereotypes women as big consumerist! there are four white women, probably in their thirties; we see that these women are more excited to see the closet than to see the rest of the house! In addition, we see that it's full of clothes even though the closet it's huge! the screamed for around 6 seconds and then we hear men screaming. The ad makes fun of women because women tend to scream and are louder than men. But in this case, men are so excited that they scream louder and longer. Anyways, we see they are screaming because his closet is a huge fridge full Heineken beers, like it was possible to have a closet of full of Heinekens. Again, four white men.

After they scream, we see "Heineken, Serving the planet" Well, I would like to know why they display that last sentence. Are they serving the planet by giving huge closets or free houses? or does it mean that they recycle? or does it mean that they help the planet by providing beer? It doesn't make any sense. What do you guys think about this?
