Espoo, the second largest city in Finland, has embraced circular economy as an important means to achieve its ambitious sustainability targets: becoming carbon neutral by 2030 and pioneering the UN Sustainable Development Goals by 2025. This ambition was triggered after ranking number one in two sustainability benchmark studies of 145 European cities conducted by Tilburg University in 2016 and 2017. Espoo wanted to retain its position as one of Europe’s sustainability trailblazers and started to not only implement more sustainable projects, but to integrate sustainability as a core pillar of the city strategy, and created the cross-functional Sustainable Espoo programme for its coordination and monitoring. As part of this programme, several circular projects are being implemented to promote sustainable lifestyles, job creation and the growth of circular businesses. By signing the European Circular Cities declaration, Espoo commits to taking this job further and embedding circular economy across the organization and the city, together with all the stakeholders.
