Decorations add festive cheer at this time of year, but can also have a carbon footprint. This year why not try:
Re-use your Christmas tree - rather than purchasing a new tree, re-use the one from last year... or look after a real tree and reuse it every year!
Natural decorations - avoid plastic decorations or those covered in glitter. How about trying pine cone decorations, or hand made bunting?
Recyclable wrapping paper - brown paper makes for a lovely vintage look when used to wrap presents... plus it is recyclable.
