christmas

When a Christmas tree ends up in a landfill it decomposes and produces methane, a potent greenhouse gas.

Methane's bad news for our climate. But here's the good news -- instead of sending your old tree to the local dump, there are more sustainable ways to dispose of it now that Christmas is over.

It's the same every year - each time Christmas comes around, your shelves become littered with cards featuring bedraggled robins and mawkish fireside scenes until they go into the recycling bin. But not this year, because we've cooked up something a little bit different.
