Sustainable development objectives have been at the heart of European policy for a long time, firmly anchored in the European Treaties [1] and mainstreamed in key cross-cutting projects, sectoral policies and initiatives. The 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs), adopted by the United Nations (UN) in September 2015, have given a new impetus to global efforts for achieving sustainable development. The EU, in coordination with its Member States, is committed to support the implementation of the 2030 Agenda and to strive towards a sustainable future for all. The EU's answer to the 2030 Agenda is outlined in the 22 November 2016 European Commission's Communication Next steps for a sustainable European future - European action for sustainability".
