The PSLifestyle project began in October 2021 under the EU’s Horizon 2020 programme, with the aim of bridging the gap between climate awareness and everyday action. Its mission is to support citizens in adopting more sustainable and circular lifestyles through a free, engaging digital tool: the Lifestyle Test.

Developed by a European consortium led by the Finnish Innovation Fund Sitra, the project has unfolded in three stages. In the first phase, Living Labs were launched in eight pilot countries - Finland, Estonia, Germany, Greece, Italy, Portugal, Slovenia, and Turkey - where citizens helped co-create and refine the Lifestyle Test. The second phase expanded outreach and user engagement through Stakeholder Workshops and other key activities in partner countries. The final phase, running through 2024 and 2025, includes strategic scaling and stakeholder consultation, with notable expansions to Poland and Norway thanks to the launch of the EU-version of the Lifestyle Test - where the app saw rapid uptake, including 20,000 Norwegian users in its first month.

The Lifestyle Test app empowers users to understand their environmental footprint and create tailored sustainability action plans in areas like food, mobility, housing, and goods consumption. Many of the recommended actions reflect circular economy principles such as reuse, repair, and waste prevention. Since its public launch in September 2023, over 440,000 users have taken the test, with strong behavioural impact shown through high levels of personal action planning.

The app has gained wide recognition, including endorsement by the President of Slovenia Nataša Pirc Musar, a feature in a BBC Storyworks video series, inclusion in IKEA Poland’s sustainability communications. It is now available in 10 countries and continues to expand.

Although the PSLifestyle project will officially conclude in September 2025, the Lifestyle Test will continue to grow, helping individuals across Europe and beyond embrace more sustainable living—backed by data, policy relevance, and real-world impact.

The project's final conference, called From Data to Action: Empowering Policies for Sustainable Choices, takes place in Brussels on 13th May, where we will reflect on the project’s achievements and explore how the Lifestyle Test can continue to advance Europe’s sustainability goals. The event will also feature a high-level EU workshop that aims to foster a targeted dialogue between key actors (policymakers, researchers, industries, and civil society) on sustainable behaviours, their implications for policy and practice and scaling PSL insights and tools in Europe.

As well as the Lifestyle Test's success in helping individuals to make changes toward a more sustainable lifestyle, another key output of the project is the huge dataset collected by the app, which offers opportunities to policymakers, governments, industries and researchers to enact real change on a structural level.
