It thus provides a means for the collective voice of European science to be heard. EASAC was founded in 2001 at the Royal Swedish Academy of Sciences. Its mission reflects the view of academies that science is central to many aspects of modern life and that an appreciation of the scientific dimension is a pre-requisite to wise policy-making. This view already underpins the work of many academies at national level. With the growing importance of the European Union as an arena for policy, academies recognise that the scope of their advisory functions needs to extend beyond the national to cover also the European level. Here it is often the case that a trans-European grouping can be more effective than a body from a single country. The academies of Europe have therefore formed EASAC so that they can speak with a common voice with the goal of building science into policy at EU level. Through EASAC, the academies work together to provide independent, expert, evidence-based advice about the scientific aspects of public policy to those who make or influence policy within the European institutions. Drawing on the memberships and networks of the academies, EASAC accesses the best of European science in carrying out its work. Its views are vigorously independent of commercial or political bias, and it is open and transparent in its processes. EASAC aims to deliver advice that is comprehensible, relevant and timely. EASAC covers all scientific and technical disciplines, and its experts are drawn from all the countries of the European Union. It is funded by the member academies and by contracts with interested bodies. The expert members of EASAC’s working groups give their time free of charge. EASAC has no commercial or business sponsors. EASAC’s activities include substantive studies of the scientific aspects of policy issues, reviews and advice about specific policy documents, workshops aimed at identifying current scientific thinking about major policy issues or at briefing policy-makers, and short, timely statements on topical subjects. The EASAC Council has 29 individual members – highly experienced scientists nominated one each by the national science academies of EU Member States, by the Academia Europaea and by ALLEA. The national science academies of Norway, Switzerland and the United Kingdom are also represented. The Council is supported by a professional Secretariat based at the Leopoldina, the German National Academy of Sciences, in Halle (Saale) and by a Brussels Office at the Royal Academies for Science and the Arts of Belgium. The Council agrees the initiation of projects, appoints members of working groups, reviews drafts and approves reports for publication.

It is not a problem that EASAC’s Environment Programme covers all aspects of individual stakeholders can solve on their own, and the environment (terrestrial, freshwater and marine) the motives and actions of individual stakeholders are as well as associated issues such as resource use not currently aligned with the overall objective of a and productivity. As the issue of the use of plastics more circular use for packaging plastics. In this report in packaging has rocketed up the political agenda, we examine the issues from a systems perspective and triggered in part by the graphic scenes of marine life highlight these potential conflicts so that they can be affected in television programmes such as The Blue better understood and addressed. Planet, the European Commission has responded with several measures to encourage the packaging industry Our Expert Group, supported by EASAC’s to evolve to a more circular framework.

It is questionable whether producers of plastic provided a solid foundation for this investigation into raw materials can continue to see their business model the role of packaging plastics in the circular economy. as based on ‘business as usual’ with annual growth rates of several per cent; it should help if packaging The current dominantly linear system leads to extensive manufacturers can simplify their current complex leakage into the environment by plastics that persist mixtures to become easier to recycle; retailers can for hundreds or thousands of years.
