What 'newer' Christmas traditions could be scrapped to help save the planet

Well, our Secret Santas used to be very amusing, with carefully chosen, appropriate and cheap presents. We were not amused when a senior manager decided of his own volition that we would instead donate to a charity of his choice, (particularly as many of us had already bought our witty, amusing and cheap presents.) and sent an envelope around for the £% donations. He also banned the sending of Christmas cards. Ignored.
You don't like them personally, therefore they must stop, under the pretence of Saving The Planet. Lot of that about at present.

We do a £1.00 present, does not break the bank, and is harmless fun.

I think the idea of controlling things like this are nonsense and often people have no idea of the impact on the environment is worse or better. Where is the evidence to show that experience gifts cause less damage to the environment than a candle say.

Christmas Boxes...given to children on Christmas Eve and stuffed with presents that they don’t need.

I agree, that's where these experience type gifts are good because they usually come with no waste. Hopefully they might take the place of the rubbish stuff.

Anything and everything made of or wrapped in Plastic.
