The Circular Economy Platform for European Priorities Strategic Agenda (CICERONE) is a project that aims to build a joint platform and strategic agenda for making circular economy research and innovation programs more efficient. CICERONE works in close cooperation with a variety of practitioners including government bodies, research & technology organisations, civil society, industry, innovative SMEs, startups, cities and investors. The goal is to enhance alignment between EU member states on where research and innovation efforts should be focused to accelerate the transition to a circular economy. The objectives and innovation fields are categorized under 12 areas (8 themes, 4 challenges). All 24 stakeholders of the consortium are invited to share their point of view and knowledge to challenge or enrich them through an open consultation from June to October 2019. This consultation is thought in 3 phases: a first conversation on objectives and innovation fields open to the 24 partners in June 2019, an open consultation to all EU stakeholders from June to August 2019, and an evaluation phase of innovation fields open to the 24 partners in September 2019. This document presents the means deployed for this consultation engagement strategy.
