I drink local (or even Brussels) beer.
I replace my bulbs with LEDs or compact fluorescents
I choose a green electricity supplier.
I buy fruits and vegetables in bulk and without packaging.
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.)
I make my own Christmas decorations (origami, cotton, cut-outs) rather than buy them and I choose LED Christmas lights.

I set my fridge at 4° and my freezer at -18° to keep my food in optimal condition.
I introduce one meat-free day a week.
