I borrow my books from the library or my toys from the toy library instead of buying them.
I place heat-reflecting panels behind my radiators.
I take the train to the airport instead of being dropped off by car
I have my mobile phone repaired rather than discarded.
I insulate the hot water pipes with foam tubes.
I drink local (or even Brussels) beer.
I set my fridge at 4° and my freezer at -18° to keep my food in optimal condition.
I wrap my gifts in beautiful fabrics instead of paper packaging.
I turn off the heating when I ventilate the rooms/rooms.
Be careful to open the windows wide for 5 minutes instead of tilt and turn window all day long!
I introduce one meat-free day a week.
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 take my used batteries and electronic products to the waste collection centre or to specialised shops.
I opt for local tourism on a small scale, with locals or camping.
I prefer to buy a wooden or second-hand toy rather than a plastic one.
I use all my leftovers to prepare a weekly meal.
