The sustainability report outlines our city’s progress from ecological, social, and economic sustainability perspectives. Sustainability is a principle that applies to all activities of the City of Lahti.

The UNESCO-designated Salpausselkä Geopark, situated in the Lahti region in southern Finland, tells the story of Finland’s best-known geological entity. The First and Second Salpausselkä are unique ice-marginal formations laid down by ancient meltwater streams at the end of the Ice Age.

We promote health and environmental well-being with the same actions. Nature Step to Health Programme is a Lahti Regional Health and Environment Programme for 2022–2032. The 10-year programme integrates the health and environmental goals of the region of Päijät-Häme in southern Finland.

Lahti aims to achieve carbon neutrality as the first major city in Finland, years ahead of the national target. Climate work will increasingly be carried out in collaboration with other cities as part of the EU’s Cities Mission.

Lahti was awarded the EU Mission Label and signed a climate agreement with the European Commission in 2024. Lahti was selected to be among the one hundred climate-neutral and smart cities participating in the EU Mission.

Many people are still learning about nature positivity. In short, it means producing more benefits for nature than harm. Currently, human activity is harming nature beyond its capacity to endure.

Lahti is emerging as Finland’s leading electric mobility hub, advancing climate goals and creating new business opportunities. The Lahti Region Electric Mobility Cluster (Lahti GEM) serves as a collaborative platform for businesses, research institutions, and municipalities to develop green electrification technologies.

Seven green renovation projects by Lahden Talot set an example for the rest of the country. With the world’s building stocks ageing, the innovative operating model also has international potential.

We develop new solutions in collaboration with businesses and other partners.
