Addressing today’s increasingly complex challenges, cities are testing and adopting new, transversal and collaborative governance practices building on citizen engagement and co-creation as well as working together across administrative borders. The growing importance of urban governance in achieving EU policy objectives is also acknowledged by the urban dimension of cohesion policy and the urban agenda for the EU. We work closely with the main EU institutions and advisory bodies, as well as with policy research organisations and other networks to strengthen multilevel governance when developing and implementing EU policies.
