Sustainable Helsinki

What does it really mean to be a sustainable city? For Helsinki, it means designing life to support life—both human and natural.

Here, sustainability is in the water, the air, the way we move, eat, rest, and relate. 70% of the city is forests and sea. Education is free, the tap water is some of the cleanest in the world, and public transport takes you from downtown to nature in minutes. Sustainability is about equality, cycling, and yes—even sauna.

Because sustaining life doesn’t just mean avoiding harm. It means actively creating the conditions for people, communities, and ecosystems to thrive.

The world’s most sustainable destination

Helsinki has been named the #1 sustainable city destination in the world by the Global Destination Sustainability Index for three years running (2024, 2025 and 2026!). The GDS-Index uses 76 indicators that evaluate destinations’ sustainability performance across four key areas: Destination Management, Supplier, Social, and Environmental.

Sustain your connection to nature

With 23,000 acres of parks and forests per 100,000 residents, Helsinki blends urban life with nature in a way few cities can. Add the sea, the archipelago of 300+ islands, and the change of seasons, and it is easy to understand why this is a city destination where you can remember that you – we, all of us – are in fact nature. Spot birds at Vanhankaupunginlahti. Pick berries in Keskuspuisto. Stargaze from a frozen sea. Hike, swim, bike, breathe.

Sustain yourself

Let sauna be your guide. In Finland, it’s more than tradition—it’s therapy, connection, pause. It slows time, evens the playing field, and softens the edges of modern life. There’s a reason the happiest country in the world is full of saunas. Sit on the laude. Feel the löyly. Close your eyes and let the steam carry you back to yourself.
