A/HRC/34/27 54. When identifying the most marginalized communities and groups of children to provide inputs to the follow-up and review of the implementation of the 2030 Agenda, States and other relevant actors should be aware of the difficulties and risks in identifying these groups, including their wish in many cases to remain unidentified by the State, and the protection risks they may face. In this regard, it is important to make use of the principle of self-identification and to employ inclusive definitions of these individuals and groups. 20 C. Strengthening accountability through input from existing rights monitoring mechanisms 55. It is vital that the follow-up and review process for the 2030 Agenda integrates the wealth of information already generated at national and international levels on human rights, including on the situation of children in especially vulnerable circumstances. This requires the consideration of information from national institutions and public oversight monitoring bodies, and information at the global level from United Nations human rights monitoring mechanisms to inform the annual reviews taking place under the high-level political forum on sustainable development. 56. At the level of national reviews, States should establish participatory processes or mechanisms whereby they can benefit from the input of parliaments, national human rights institutions, labour inspectorates, children’s ombudspersons and ombudspersons for persons with disabilities, among others.21 57. Particular attention should be paid to the integration of information from specific accountability mechanisms and initiatives tracking the protection and promotion of children’s rights. One important initiative is the global study on the situation of children deprived of their liberty, which will review the circumstances of children in detention worldwide and provide recommendations on their protection. In addition, the recently launched Every Woman Every Child’s independent accountability panel will provide the high-level political forum with important in-depth information on the health and rights of women, children and adolescents. Its work will be complemented by that of the High-level Working Group for the health and human rights of women, children and adolescents. D. Ensuring the accountability of all actors involved in partnerships for implementation of the 2030 Agenda 58. Diverse forms of partnerships will be central to delivering on the 2030 Agenda and will be a cornerstone for the realization of child rights in its implementation. Multisectoral partnerships, involving all relevant actors, are important for enabling collective action, commitment and funding for particular issues and are thus needed to accelerate progress in the implementation of the 2030 Agenda. Innovative financing solutions and partnerships with the private sector are also being expanded to deliver on the commitments in the 2030 Agenda. In this context, States are under an obligation to ensure that all actors involved in implementation initiatives, including the private sector, respect human rights, including the rights of the child. All actors involved should also be accountable under the follow-up and review processes at all levels. 20 21 OHCHR, “A human rights-based approach to data: leaving no one behind in the 2030 Development Agenda” (2016).
