Lahti, located in southern Finland, is the capital of the Päijänne Tavastia region and has over 110,000 inhabitants. Lahti experienced rapid growth and industrialisation after the Second Word War, presenting the city with economic opportunities alongside environmental challenges. Lahti has committed to overcoming these challenges and has shown vast improvements in a range of environmental areas, including sustainable land use and water management.


Nature & Biodiversity

Lahti has a rich history of nature conservation and encourages active participation from a range of stakeholders in its environmental programmes. Through initiatives such as the ‘outdoor kindergarten’ and ‘environmental grandparents’, Lahti is committed to engaging citizens of all ages in protecting their environment.

Air Quality

Lahti has a clear strategy for improving its air quality, focusing on reducing traffic in the city. Measures such as introducing pedestrianised zones, encouraging walking and cycling, and promoting electric vehicles will help Lahti achieve its air quality targets as well as improve its urban environment.


Lahti has demonstrated a commitment to public engagement in its water management. Collaborative action undertaken by residents, students and local companies was successful in restoring the water quality of Lake Vesijärvi, reversing the negative impacts of the city’s rapid industrial growth.

Lahti has also focused on improving its wastewater management, through investments in facilities, as well as storm water management, including the construction of wetlands and retention ponds to capture water from heavy rainfall and prevent flooding.
