At Science For Change we address social, environmental and health challenges through citizen science, participatory strategies and co-creation. We are an innovative company expert in collaborative research, evidence-informed policies and quality scientific communication. SfC specializes in developing user-centered, basing the services and products on citizen science. It focuses on the methodology quadruple helix model, where stakeholders such as policymakers, industries, academia, NGOs and communities are involved in all steps of the process. SfC empowers communities using a bottom-up approach to co-design local solutions adapted to each case, while promoting the participation of citizens in decision-making processes that affect their quality of life. SfC has been created for the exploitation of results of the EU H2020 project D-NOSES (Distributed Network for Odour Sensing, Empowerment and Sustainability) with the aim of co-design alternative solutions to odour pollution using citizen science.
