Lahti is Finland’s leading environmental city and one of Europe’s pioneers of sustainable development
Our story as an environmental city began with the restoration of Lake Vesijärvi in the 1970s. Since then, we have implemented numerous small and large environmental actions and emerged as one of Europe’s most progressive environmental cities. Our work continues with new and bold initiatives in close collaboration with universities, businesses and residents.
Lahti had the honour of being the European Green Capital in 2021. We are also proud participants in the EU Cities Mission, where we are one of a hundred European climate-neutral and smart cities. Our goal is to become the first of Finland’s major cities to achieve climate neutrality.
Story of Lahti
City of Makers
It all started with cleaning up Lake Vesijärvi, and it has progressed to personal carbon trading today with a carbon-neutral daily life in the future. We have discovered solutions for environmental challenges and made Lahti a leading environmental city and the European Green Capital together.
As most Europeans live in cities the size of Lahti, we set an excellent example to an enormous number of people.

Translating the silent dialogue of nature
Ahti Pulli is writing his master's thesis in ecology and evolutionary biology on the diversity of meadow ecosystems. Pulli started his degree course amid the coronavirus pandemic when birds became a source of comfort for him and gave him an escape from a life of isolation. Pulli hopes that urban planners, in particular, will discover his thesis when it is published next spring.
