A/HRC/34/27 the most marginalized children and those at greatest risk of being left behind are reached. In accordance with the obligations of States under international law, the protection of children’s rights must take precedence in respect of all aspects of national planning, implementation and the monitoring and review process for the 2030 Agenda for Sustainable Development. 65. A universal, integrated approach is needed to implement the 2030 Agenda in a manner consistent with human rights, including the rights of the child, recognizing the relevance of each of its 17 Goals to all children in all countries. Specific approaches and measures are needed in this respect throughout the implementation, monitoring and review processes of the 2030 Agenda. The starting point for the protection and realization of children’s rights is to ensure that no implementation activities are undertaken that would risk undermining their rights, including as a result of unintended consequences. 66. Delivering on the pledge that no one will be left behind and those furthest behind will be reached first is central to the realization of children’s rights. It requires placing the elimination of discrimination and reduction of inequalities at the forefront of efforts to implement the 2030 Agenda alongside the prioritization of implementation efforts to reach those children at greatest risk of being excluded first. 67. Children’s rights must also be integrated as a core consideration in all programmes, policies and frameworks aimed at achieving the 2030 Agenda and not as an afterthought. States must foster supportive environments in this regard by ensuring that legislation, policies and measures to promote equality and nondiscrimination are in place, in accordance with international human rights. 68. Furthermore, specific child rights obligations pertaining to financing, national planning and the monitoring and review process must be respected and fulfilled. This requires adequate financing and investment in children, prioritizing those in situations of greatest vulnerability and marginalization; participation throughout the implementation and follow-up and review processes, with effective measures to bring about accountability; and a human rights approach to data and monitoring, including through transparency and quality disaggregated data to reflect the situation of all children, particularly those who are too often uncounted, yet also at greatest risk of being left behind. 18
