PSLifestyle

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 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, included 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 project is funded by the EU’s Horizon 2020 program, which supports innovations that offer impactful solutions.

The project began in autumn 2021 and ended in September 2025.

Almost 70 percent of Europe’s climate emissions can be traced back to people’s everyday lives – how we eat, live, travel, and consume. The PSLifestyle project aims to bridge the gap between people’s climate awareness and concrete actions by providing an inspiring and practical tool for adopting sustainable lifestyles.

PSLifestyle aims to develop a locally customizable online service in eight EU countries (including Finland, Estonia, Germany, Greece, Italy, Portugal, Slovenia, and Turkey) that individuals can use to create their own plans for living within the 1.5-degree climate target.
