LAHDEN KAUPUNKI

Their core work

The City of Lahti is a Finnish municipal authority that functions as a real-world implementation site and urban living lab for EU-funded research. In H2020, Lahti contributed city infrastructure, public health data, and resident populations to test nature-based solutions for urban wellbeing and citizen-driven climate mitigation strategies. Their practical value to research consortia is access to a real city environment where interventions can be deployed, measured, and scaled. Lahti has positioned itself as one of Finland's most active municipalities in green transition, making it a credible partner for projects that require on-the-ground urban testing rather than lab-based validation.

What they specialise in

How they've shifted over time

Lahti's earliest H2020 involvement centred on the physical and psychological dimensions of green urban space — using parks, routes, and nature exposure to improve mental health and resilience. By 2021, the focus had shifted toward the behavioural and data science side of climate action: modelling how individuals change lifestyle habits and tracking those changes through smartphone apps and citizen science frameworks. This is a clear move from passive infrastructure (green routes people walk) to active participation systems (apps that track and nudge behaviour). The trajectory suggests Lahti is building capacity at the intersection of urban governance and digital citizen engagement for the green transition.

Lahti is moving toward digital-physical hybrid interventions where city residents become active agents in climate mitigation, pointing toward future collaborations in smart city governance, participatory climate planning, and app-based public engagement.

How they like to work

Lahti participates exclusively as a consortium partner and has never taken a coordinating role, which is typical for municipal authorities that offer real-world implementation capacity rather than research leadership. Both projects placed them inside large multi-partner consortia, consistent with a city that opens its territory and resident base to research teams rather than driving the scientific agenda. Working with Lahti means gaining access to a cooperative municipal partner willing to mobilise residents, city spaces, and local government backing — but the scientific and coordination work will need to come from elsewhere in the consortium.

Despite only two projects, Lahti has reached 68 unique consortium partners across 25 countries, indicating participation in genuinely large international consortia rather than small bilateral collaborations. Their network is broad and European in character, without a visible geographic concentration beyond the Nordic region.

What sets them apart

Lahti is one of Finland's most publicly committed green transition cities, having declared a goal to be carbon-neutral well ahead of national targets — which gives it credibility as a pilot site that research consortia can point to as a serious policy environment. Unlike a university or research institute, Lahti brings administrative reach: the ability to communicate with thousands of residents, integrate interventions into city services, and provide political legitimacy to pilots. For projects that need a Nordic city partner combining environmental ambition with a manageable size for experimentation, Lahti is a well-matched choice.

Highlights from their portfolio

• GO GREEN ROUTES
  The largest investment in Lahti's H2020 portfolio at €505,000, this project tested nature-based urban solutions across multiple European cities, with Lahti serving as the Finnish pilot site for linking green infrastructure to measurable public health outcomes.
• CAMPAIGNers
  Technically ambitious for a municipal partner, this project connected Lahti residents to integrated assessment modelling and behavioural science tools — unusual territory for a city administration and a signal of Lahti's appetite for data-driven climate governance.
