Are you looking to have a green-themed Halloween costume? Maybe want to make some Halloween crafts with the environment in mind? We’ve got you covered – because why not dress up for Halloween and simultaneously raise awareness to current and worsening environmental issues?!


Below we have given you a few great costume ideas that will surely be conversation starters at any party you go to (be it in person, or remote).


With all of these ideas, we (of course) suggest rummaging at a clothes swap, visiting your local thrift store or asking a friend for clothing supplies – don’t buy new for Halloween!


😱. But first, here are a few scaaaaaryyy Halloween statistics ….

Halloween Costume Idea: Greenwashing

Refers to fashion companies claiming that their products are environmentally friendly, when often they are not.

For this costume you need to dress head to toe in green and attach labels to yourself that say things like, “Eco-friendly” and “Made from 3% recycled materials.”


Make a washing machine costume out of old cardboard boxes and paint it green! – No green paint? Ask a friend, post on your community Facebook or visit your local dump (where old paint cans are usually redistributed to the community).


Dress up as Rising Sea Levels!

 … an increase in the level of the world’s oceans due to the effects of global warming.

Cut out several pieces of paper and write the word ‘Sea’ on them (or the letter C if you like a good pun), dress completely in blue, then attach the individual pieces of paper to your clothing beginning at the bottom of your pants, all the way to the top of your shirt. Make sure to have most of them concentrated around your neckline.

Use scrap paper that’s due for recycling!


The Great Pacific Garbage Patch:

Sadly a relatively unknown issue outwith ‘green circles: ‘The Great Pacific Garbage Patch’ is sure to a conversation starter! Incase you don’t know, it’s a collection of marine debris in the North Pacific Ocean. It’s a really great point to raise as it will naturally bring up plastic waste and the unnecessary purchasing of single-use products.

Dress in blue from head to toe, then safety pin plastic bottles, knives, forks,  straws and other garbage that can be found in the sea. Cut all of them and stick them all over your outfit, with the majority of the cutouts concentrated in one area to create the garbage patch. A great combo of a Halloween costume and a Halloween craft in one for you crafty folks!

An Endangered Species!

Sadly, there are too many to choose from. The WWF keep an accurate, up-to-date list based on severity of endangerement for inspiration.

Easy to actualize costumes that suit this topic would be:

Sunda Tiger;
… or a Hawksbill Turtle. 

Another endangered specie (and an RAOG fave!) would be the pangolin. We recently wrote a blog about the plight of the pangolin with help from Random Acts of Green business member, Fanimal. You can see it here.

If you do dress as an endangered species, bring 3 facts about the animal, and one way in which your party pals can help them.

We’ll get to the Halloween Crafts soon! but first, another Halloween costume idea – Forest Fires

Forest fires were a hot headline in 2021, with wildfires ablaze in many parts of the world leading to loss of land, lives and habitats.

Talk to your friends, family and coworkers about forest fires and the reasons for them through a thought provoking, colourful costume!

Make a cone shape out of an old cardboard box, or envelope then paint it green. This will be your hat – aka a tree top!

Dress in reds, oranges and yellows. Tear up old bits of clothing and attach them to yourself like licking flames (don’t worry! You can use them as cleaning rags after).

Two more ideas as submit by our community members last year:

A big thank you to our Green Ambassador: Meghan Walsh from Kingston, Ontario who shared this wonderful, DIY dress that represents Climate Change and to our Green Spotted Volunteer, Eileen who went as a Blue Box Recycling Bin!!

👻 Now for some fun Halloween Crafts! 👻

🦇 As we mentioned in our infographic: pumpkins usually go to waste over the Halloween season. Don’t contribute to the 17% of food that’s wasted globally each year (UN). Instead, decorate your porch with a series of old jars. Pop a tealight in your jars, then cut out spooky halloween shapes and faces to stick on the front.

🦇 Take white (or black, grey and orange) cleaning cloths and make little ghosts like the above. This is a great waste free halloween craft and they’re super easy to make and a really fun family activity plus – no waste! (purplepumpkin blog pic.)

🦇  If you’re a fan of the macabre – Use old cardboard boxes to make gravestones. Paint punny names and dates on the front (The Simpsons are sure to provide you with great inspo!), then rake leaves into mounds in front of them! If you want to be super fancy Instructables has a fantastic blog here which shows you how to make 3d gravestones!

🦇  String up a giant cobweb (or two!) in your front windows. You can always use the yarn afterwards.

🦇  Paint some fall leaves with little bat eyes and fangs – a great halloween craft that’s fun for the whole family! (goodhousekeeping pic.)
