A/HRC/40/50 process will feed into the midterm evaluation of the Strategy, to be hosted by the Government of France in November 2019. 89. The Committee of Ministers of the Council of Europe adopted new standards on violence-related concerns, including in April 2018 on safeguarding the rights of children of imprisoned parents, and in July 2018 on the rights of the child in the digital environment. The latter set of standards promotes children’s empowerment and protection through the development of legislation and policies, the strengthening of national and international cooperation, and enhanced partnerships with key stakeholders. 90. Additional work was pursued on the rights of the child in migration, with special emphasis on age assessment and guardianship of unaccompanied and separated children. The Council of Europe prepared a handbook for professionals working with children affected by migration to help them communicate in a child-friendly way about children’s rights and the procedures affecting them, in accordance with the age, maturity, language, gender and culture of the child.23 91. The European Union has continued to promote important initiatives to prevent and address violence against children in both its internal and external action, including with respect to strengthening national child protection systems, enhancing child safeguarding standards, building the capacity of professionals, and supporting the delivery of integrated, multidisciplinary services to child victims of violence. 92. In December 2018, the President of the European Parliament appointed a new coordinator for children’s rights to ensure that the rights of the child were fully respected in European Union legislation and in other initiatives promoted by the Parliament. The coordinator will act as a focal point for engagement between the Parliament and other institutions and agencies involved with the development and implementation of European Union policy related to children’s rights, as well as with the United Nations system and civil society organizations. V. Children as agents of change 93. Partnering with children is a crucial dimension of the Special Representative’s mandate. Listening to children’s voices and experiences is critical to realizing the vision of the Convention on the Rights of the Child and the 2030 Agenda of a world free from fear and violence. 94. As the Ministerial Declaration from the 2018 high-level political forum on sustainable development noted, children are important agents of change and their meaningful participation is vital for the effective implementation and review of the 2030 Agenda. The 2019 forum theme of “empowering people” and the forum’s review of Sustainable Development Goal 16, alongside the thirtieth anniversary of the Convention on the Rights of the Child with its crucial attention to children’s agency and participation, will give children’s engagement and support for violence prevention and response initiatives a special relevance. 95. Violence was a top concern for the more than 800,000 children who participated in consultations informing the development of the 2030 Agenda. This priority was reconfirmed by an online opinion poll on migrant and refugee children, conducted by the Special Representative and UNICEF. Of more than 170,000 young people surveyed, a large percentage saw violence as a serious issue associated with children’s cross-border movements. Violence was identified as a key reason for children leaving their country, a major challenge faced during their journey and an ongoing problem when they arrived in destination countries. 23 14 See https://rm.coe.int/how-to-convey-child-friendly-information-to-children-in-migration-aha/1680902f91.
