Science for change tools: the new methodological toolbox to create zero-waste collaborative workshops

Collaborative practices are more common every day in contexts where citizens of different backgrounds need to be involved in science and decision-making processes. These practices often translate into co-creation workshops, in which we find two main issues to address. First, the lack of an expert to guide the sessions and second, the quantity of consumable material that is used in these activities. In order to address these two issues, we have carried out an experimental study in 22 citizen science projects that has brought us to develop a sustainable toolbox for collaboration. This paper summarizes the experience of presenting and testing the toolbox with citizen science experts at the ECSA Conference 2024.
