I freeze my food before the expiry date instead of throwing it away.
I use all my leftovers to prepare a weekly meal.
I choose a fridge and a washing machine A+++

I regularly defrost my freezer (every 6 months).
I drink local (or even Brussels) beer.
I have my mobile phone repaired rather than discarded.
I avoid air conditioning as much as possible (if I am too hot I hang a damp sheet on my window to cool the room. If that's not enough, then I prefer the fan.)
