The Carrefour mondial de l’accordéon has had a sustainable development policy since 2015. Several concrete actions have been carried out since then in the different editions. Here are some measures taken for 2022:

• Installation of a water fountain on the exterior site of the Accordion Museum. A fountain will also be installed by the City of Montmagny near Place Montel; 
• Consignment beer glasses will be available at event bars; 
• Acceleration of efforts to recycle materials and compost on sites;
• 90% of goods and services are purchased in the City of Montmagny or from local suppliers.

Single-use plastic (straws, glasses, water bottles) will be phased out gradually in 2022 and 2023, then completely banned in 2024.
