The aim of the project is to organize a conference “The sustainable transition to a low carbon, climate-resilient circular economy: Creating the knowledge base, CE2019” in cooperation with the Finnish government. The CE2019 conference will be part of The Sustainable Days 30.9.-1.10.2019, Presidency Event Finland that will be organized partly jointly and partly in parallel with two conferences that are: Sustainable and smart manufacture (MF) and Sustainable innovation (SI). The event is planned as a flagship event during the Presidency of the Finland of the Council of the European Union on 30 September to 1 October 2019. The opening sessions on the first day of the two-day The Sustainable Days 30.9.-1.10.2019 will be organised jointly by the three separate conferences, while the second day programs are conference-specific, taking place in parallel and in the same venue. The second day will end to a joint adjourn, that summarises and concludes the main findings and messages of the opening session and the three conferences, as well as draft key messages and recommendations for future actions on sustainable transitioning towards low carbon, climate-resilient circular economy in the European Union. Organising the three conferences jointly and in parallel is expected to bring several benefits, in particular as regards the visibility, spreading the information and invitations, management of the events, as well as the impact, networking, and sharing of knowledge and resulting in common learning. The CE 2019 conference will be addressing the state-of the art of science in circular economy. The aim is the identification of policy options and priorities via review and assessment of developments, and sharing of information and comparison of points of views; and efficient networking of various stakeholders and support to their activities, e.g. natural scientists, social scientists, businesses, investors, local authorities, environmental organisations, museums and schools.
