As much as I adore Halloween with every fibre of my being, it’s not an eco-friendly holiday. With so much cheap, over-processed single-use items plaguing the season, we need to think of ways to have an eco-friendly Halloween.
An estimated 2000 tonnes of waste will be generated from Halloween costumes alone this year. There’s so much single use waste from costumes, to candy, and cheap decorations, and there’s no need for it. We can make the most of spooky season without contributing to plastic pollution and the climate crisis. Here’s how to be eco-friendly this Halloween:
How To Have An Eco-Friendly Halloween
1. Green Costumes

Halloween is probably the biggest night for single-use costumes. I love good Halloween costumes as much as the next person, but buying an outfit and wearing it for a few hours once is not sustainable. The environmental impact that goes into making just one outfit isn’t nothing, so at least get the wear from your wardrobe!
I’m not saying you can’t dress up. I start thinking about my costume very early in the year, I’m just suggesting to be more considerate with it. Most single-use Halloween costumes are so cheap and flimsy they don’t even look that good!
Wear Outfits You Already Own
I always try to use things I already own as part of my Halloween costume.
When I was Veronica from Heathers I didn’t need to buy a single thing because all the clothes were either mine or my sisters! When I was Wednesday Addams I wore all my own clothes too.
Smart Accessories

For other costumes I bought accessories to accompany things I already own, like buying the wig and bullet belt for Black Widow, and the wig, gloves, feather boa, and cigarette holder for Cruella. When I buy new things I always get something I feel can be used for another costume down the line or I’ll actually wear again. Last year I was Esmerelda, and only had to buy the corset and skirt, which I would actually wear in my day-to-day life.
Shop Secondhand
This year, I only bought secondhand; I got the red blazer on Depop, and I’ll pick up a sword in a charity shop. Everything else was something I already owned, the shirt for Elizabeth and Esmerelda are the same!
Instead of buying a new costume, shop second-hand, have a look at what you have, or borrow something.
2. Low-Waste Candy

Unfortunately most wrappers from sweets aren’t recyclable. If you stop and look at the waste that washes up on the beach, a lot of the single-use plastic is decades old. Halloween candy is no different, the fact that these companies make new packaging for Halloween is a waste of plastic.
I’m not saying the solution is to hand out loose fruit, because the kids will throw it back at your house. I think the solution is to track down sweets in sustainable packaging – which is few and far between right now.
Chocolate brands like Seed & Bean and Vego’s white chocolate bar have biodegradable packing. They also have the added bonus of no palm-oil. You could make chocolate apples with these!
3. DIY Or Buy Eco-friendly Decorations

I love seeing Halloween stuff in stores. Usually I buy at least one thing a year, but I only buy good quality things I love. I actually keep a few Halloween things in my room all year. A lot of decorations are low quality and won’t make it until the next Halloween. Get things you can reuse the next year. Have a look in charity shops first for new decorations.
The greenest thing you can buy, is nothing, but I don’t want to be the Grinch of Halloween. You can shop sustainably, but before buying something ask yourself a few questions for your eco-friendly Halloween:
- Do I need this?
- Do we have enough decorations?
- Will it last a few Halloweens?
- Is this an impulse buy?
The most important decoration, after all, is the pumpkin, which is already biodegradable.
Better again, DIY some decorations, Pinterest is a goldmine for these kinds of projects.
4. Reuse What You Can

This leads on from my point about getting good quality decorations or DIYing them for your green Halloween. Reuse what you can!
There’s a lot of throwaway culture surrounding Halloween; when I was a kid I rewore the same costume for years on end because my family didn’t see the point in being something new every year.
For some reason, we always got new trick or treating bags. Trick or Treating bags are often so low-quality they only last the one Halloween. One year mine broke, and some kid just followed me, eating the trail of my sweets. It makes much more sense to buy a good quality bag, like a canvas tote bag, to be used for many Halloweens to come.
Even if you’re not going to be the same character every Halloween, keep your costumes to mix and match! For example, a Daenerys wig could be braided for an Elsa costume, my Esmerelda corset would work for a pirate-look!
Are you planing on having an eco-friendly Halloween? If so, what green practices are you adopting? Check out my guide on upcycling a Jack-o-lantern.

I don’t really do Halloween costumes because my clothes are so out there and unique that it’s like Halloween every day for me. One other thing I thought about for environmentally friendly Halloween costumes that anyone can do without buying anything is Disneybounding, where you wear outfits inspired by Disney characters colour schemes. Like for a Winnie the Pooh Disneybound wear yellow and red and for Piglet wear pink. This could work well in a friends group.
I love your style! The Disneybounding thing is a really good idea, I never thought of it!
Thanks Aisling!
I love this! I haven’t seen anyone go over how to be green this Halloween yet. I always do DIY costumes with clothes I already have, I think its funner and more of a challenge (and they look better than store bought that way). I also get a few things each year; usually ceramics or investments. Now times have changed it is a bit strange seeing so many throw-away plastic masks and things of that nature. Pumpkins really are the best Halloween decorations for their eco friendly nature! (I especially like going to pumpkin patches; seems extra authentic that way!) Great post and tips 🙂
Great post and probably something not many people think about when it comes to Halloween celebrations. I don’t ever do anything for Halloween, so that’s good in that I’m not adding to the damage! x
I agree to buy something that lasts for years – after all, it is only used once a year. Why not display it over and over? We do that with Christmas decorations!
I loved the idea behind this post! I’ve been doing my best to be greener this year but I never thought about the big holidays! Thanks for the tips! x

yes! im always on the look out for more long term decorations that i can enjoy year round, theres some fab stuff but on closer inspection im always put off when it looks cheap
We try and DIY for Hallowe’en as much as possible – pumpkin carving and making our own sweets. But I do know what you mean, the majority of crap that’s pushed at us for what’s essentially one night is dreadful! Great eco-tips here 🙂 Lisa x
Loved this post! I always try and reuse or repurpose costumes – and I agree with the point about wrappers being tough to find eco-friendly alternatives, but avoiding palm oil is a good start!

Such a great post! I love Halloween, but always feel a bit strange about all the plastic decorations etc.. It’s definitely a good idea to buy something that’ll last, rather than some single-use poorly made decorations 🙂 I’m going as Kiki from Kiki’s Delivery services this year – just a black dress, some red shoes and a red bow, super easy c:
That’s a great costume!
This is a great post and a topic I haven’t seen discussed before. We love Halloween in my family and try to get costumes we will reuse, or use items already in our wardrobes. One thing I have tried before is making our own chocolates or cupcakes, which is a great alternative to anything store bought. The kids loved them. 😊
That’s exactly my thoughts for this Halloween. Thanks for the post.
