The True Climate Cost of Halloween — And How We Can Solve It While Still Enjoying the Holiday

In the United States, Halloween rivals Christmas concerning money spent, time decorating, and, most importantly, waste created. In 2022, $10.6 billion was spent on Halloween by Americans. The average person spends about $100 on Halloween yearly, on candy, costumes, and decorations — and that number is increasing after the Covid-19 shutdown. This year, Halloween spending is expected to reach $12.2 billion, according to the National Retail Federation. However, the items bought for this holiday often become waste by November 1.

The Halloween waste leads to overcrowded landfills and increased methane production, a key contributor to climate change. Much of this waste comes from costumes. About 80 percent of costumes are made from cheap synthetic materials, including polyester. These materials are typically non-recyclable, and most costumes are discarded after just one use. The result? Costumes fill up landfills.

Quick calculations reveal the scope of the problem. 69 percent of the American population plans on wearing costumes this year — that is around 231 million costumes, based on census data from January 2023, 184 million of which cannot be recycled.

Halloween candy also has a large impact on climate change. The plastic waste from the candy becomes litter throughout streets and joins costumes in landfills. In addition, the production of chocolate has a profound environmental impact, especially from larger companies which are more common around Halloween. The chocolate industry is a large contributor to deforestation, causing both climate change and biodiversity loss. West Africa, which grows 70 percent of the world’s chocolate, has lost 80 percent of its forests since 1970. The rate of deforestation has only increased in the past decade. Companies also clear forests to plant palm trees in an effort to harvest palm oil, another popular ingredient in chocolate and other candies.

Costumes and candy are not alone. One billion pounds of pumpkins are grown annually in the United States, mostly harvested for Halloween and Thanksgiving. Almost all end up in a landfill.

So what can you do to help?

Despite Halloween’s environmental cost, we can still enjoy the costumed holiday — with a few modifications.


In order to reduce the environmental impact of your pumpkins, consider buying or picking pumpkins from local farms or growing your own pumpkins. The less distance a product has to travel, the lower its environmental impact. In addition, try carving pumpkins rather than painting them, since most paints make the pumpkin no longer compostable.

Using the entire pumpkin also helps minimize environmental waste. You can eat pumpkin seeds rather than throwing them away — roast them or make them into granola. You can also use the insides of pumpkins to make pumpkin pie or other sweet treats. When you’ve used all the parts of the pumpkin you can, compost the rest! They are 90 percent water, adding moisture to the soil and helping plants grow.


Another way you can be more sustainable on Halloween is by thrifting a costume or using what you already have to turn into a costume. Making your own costume would also reduce your environmental impact as you could choose sustainable materials to use. If buying a costume, buy items of clothing that you’ll wear again instead of only once. If you need to, you could even rent a more specific costume.


In terms of candy, buy organic alternatives to reduce your environmental impact this Halloween. If you cannot buy organic, check the ingredients on your candy to ensure they are sourced sustainably. Try to avoid candy with palm oil if you want to be more sustainable. You could also look into corporations that source cocoa ethically from small farmers. Other than ingredients, you can choose candy with paper instead of plastic packaging so wrappers are easier to recycle. Or, buy in bulk to reduce plastic packaging. You may even want to try and make your own candy or treats to hand out this Halloween.

Other things you can do include reusing or making decorations yourself, using reusable cups, plates, and utensils to reduce waste if throwing a party, and using household items for trick or treating such as pillowcases, buckets, and bags. These solutions aren’t perfect and leave a lot to be desired to improve Halloween’s environmental impact, but they provide a nice middle ground between enjoying the tradition and protecting the planet from our consumerism.
