Cremation uses fossil fuels, and emits carbon dioxide and toxic particulates into the atmosphere. About about 1.6 million people are cremated in the United States each year. Human composting is a more eco-friendly funeral option than cremation because it saves one metric ton of carbon dioxide from entering the atmosphere for every person who chooses it.
Each person who chooses human composting prevents the emissions equivalent of over 40 propane tanks. Conventional burial also creates emissions from the manufacture and transport of headstones, caskets, and grave liners, and requires ongoing upkeep of cemeteries.
