European Paper Bag Day is observed worldwide every October 18 to encourage the use of paper bags instead of single-use plastic bags, which are significant pollutants. Launched in 2018 by The Paper Bag platform, it aims to promote the benefits of paper packaging and is supported by organizations such as EUROSAC and CEPI Eurokraft. Events associated with this day include public awareness campaigns, recycling projects, and outdoor activities that advocate for environmentally-friendly lifestyles. Countries that have participated in European Paper Bag Day include Austria, Belgium, the Czech Republic, Finland, France, Italy, Russia, Spain, and the United Kingdom. Participants are encouraged to use paper bags and share their commitment on social media with the hashtag #EuropeanPaperBagDay. The observance highlights the sustainability of paper bags, which are made from renewable materials, reusable, and recyclable, in contrast to the environmental impact of plastic bags.
