Sustainability is a major trend across the global events industry—and in Helsinki, it’s already a way of life. Many of the city’s most beloved public events are organised with responsibility at heart, combining unforgettable experiences with climate-conscious planning.

Helsinki Events Foundation leads the way by producing high-impact, low-footprint festivals that celebrate food, light, art, music, and community. These events are free and inclusive, welcoming locals and visitors alike, while paying attention to everything from waste reduction and energy use to accessibility and local partnerships.

From cosy winter markets to dazzling summer celebrations, there’s a sustainable event for every season.
