If you buy a cut tree, skip the shiny "icicles" so it can be mulched and composted after the holidays. 

If you decorate with lights, choose LEDs and turn them off before you go to bed.

Plan meals using more local ingredients. 

Wrap gifts with plain paper neither shiny nor plasticized, so it can be recycled.  Better, wrap in reusable fabric, such as a bandana, towel, etc.

If you receive a gift that replaces a current possession, ensure that someone else can use it.
