I looked into the "green" aspects of artificial trees versus live trees, a few years ago...
As I started my research, I expected to find that artificial trees were more "green", and that live, fresh trees were more harmful to the environment... I already had several GORGEOUS artificial trees picked out, from which I was eager to select my future Christmas tree.
But as I looked further into it, I was astonished by what I found...
LIVE trees are actually "greener"...!!
The reason?
They're grown on "tree farms", and said "tree farms" offer GREAT shelter for wildlife. Plus, they're usually grown by small farmers- and it helps bring in extra income for the small farms, too...
The same can be said for small farms/ranches who allow you - for a fee - to go cut trees on their land.
If your town has an After-Christmas "tree recycling" program, it means that the used trees will become mulch - here in Denver, they use the mulch for city landscaping and especially use it for environment landscaping at the Zoo.
On the other hand, artificial trees tend to be cheaply built, and are often thrown away after a few years - thereby clogging the landfill/trash dumps with prickly plastic and wire non-bio-degradable crap...
BUUUUUUT....
There are "green" artificial trees out there, now. Made from recycled plastic bottles - they're a bit pricier, but often better-made, and therefore more likely to last you many, many years...
ON THE OTHER HAND.....

I LOVE living, green trees!! They smell SO GOOD!!!
Here are my tips for handling live trees - since that's what we get, every year:
First, buy a GOOD tree.
I've made the mistake in the past, of buying crappy trees from King Soopers - NEVER buy a tree from a grocery store chain!!
I found that Home Depot - in our area - carries the BEST trees - and they're priced about the same as the crappy trees from the Snoop - aka King Soopers...
Second, once you've picked out a good tree....
When you get it home, lay it down gently in your driveway and get a couple buckets of warm to very warm water. Add a few drops of liquid dish detergent to the water as you run it, then take the buckets out to the tree and douse the tree thoroughly.
This will help knock off any lingering beetles, spiders, bugs, and forest floor debris...
Use a couple more buckets of water to rinse the tree off, LEAVE THE TREE OUTSIDE TO DRIP-DRY - preferably upright, then go inside and prepare your tree stand. Do NOT put water into the stand until the tree is in position, but prep the tree stand before hauling the tree inside.
We lay down a plastic trash bag first, then newspaper, then place a cardboard box down before positioning the tree stand on top. The bag and newspapers underneath the tree stand will help to catch any extra water, if you happen to overfill the tree stand later on...
Now, as long as the tree is still outside at this point, cut off the bottom 4 inches to 6 inches of the trunk, and shape the very bottom of the tree if needed...
Bring the tree inside, position it in the tree stand and screw the metal screws into the tree; make sure that the tree is completely stable, then add HOT WATER to the tree-stand basin.
At this point, you can also mist - spray - the tree with cold water - this will close the tree's pores and help it retain water.
When you place the tree-skirt around the tree, keep the misting spray bottle, a flashlight and a long-spouted plant watering can next to the tree, so you can add water [nearly every day that the tree is up] - BUT CHECK THE WATER LEVEL FIRSTand ONLY add water- warm water - as needed, and mist the tree with cold water occasionally.
If you're going to have a party and you want the tree to smell especially nice, then mist it with very warm water just before the guests arrive. That OPENS the pores and causes the fresh, crisp pine-tree fragrance to out-gas from the tree...
If you buy the freshest tree available, have pre-washed the tree, keep the tree well-watered and misted, that will drastically reduce the loss of needles. Needle-loss is caused by an over-dried tree that was harvested too long before being sold.
Live trees are more work, but in my opinion, they are well worth it!
