Drawing on tested approaches across six European pilot cities. Each toolkit addresses a distinct challenge, from a comprehensive how-to guide for cities, creative commissioning for environmental monitoring and an adaptive co-governance model.
Urban ReLeaf’s toolkit is a complete “how-to” guide for cities facing challenges like heat stress, air pollution and greenspace management, that are seeking innovative ways to produce knowledge collaboratively.
By linking local action to EU and national policy ambitions, it charts practical pathways and acts as a catalyst for continued impact—guiding innovation, investment, and collaboration toward more participatory, inclusive, and resilient urban futures. In this vision, citizen observations, engagement, and citizen science become cornerstones of evidence-based urban governance, fully embedded in how cities learn, plan, and transform.

The Roadmap sets out an inspiring, forward-looking direction for how cities, communities, and institutions can embed and scale citizen observations and data in urban planning.

Urban ReLeaf Adaptive Co-Governance Model
A practical framework for cities and public authorities to embed citizen-powered science into inclusive urban greening. Built on insights from six pilot cities and the project’s Community of Practice, the model guides institutions through five iterative phases, from co-framing and visioning to adaptation and scaling. Its aim is to make citizen-generated data a trusted, lasting part of how cities plan for green, resilient, and equitable futures.
