A/HRC/33/31 advice in order to contribute to the discussion on the implementation and realization of the right to development and on relevant implications of the 2030 Agenda.37 49. These recommendations point to the future direction of the work of the Working Group and their implementation may contribute to making that work less politicized and more attuned to the ongoing intergovernmental process for the implementation of the Sustainable Development Goals. IV. Conclusions and recommendations 50. The 2030 Agenda for Sustainable Development can be considered an eminent international development policy and action agenda for the realization of the right to development. It is informed by and grounded in the right to development; indeed the right to development and, by extension, all human rights are at the heart of the 2030 Agenda. 51. The 2030 Agenda must be implemented in line with international law, including international human rights law. All human rights, including the right to development, must guide the implementation process at all levels. 52. Operationalizing the commitment to leave no one behind demands a coherent and integrated United Nations system-wide approach. All United Nations system policies and programmes relating to the implementation of the 2030 Agenda should therefore be explicitly anchored in and aligned with all human rights, including the right to development. Human rights principles and standards, including those of the right to development, should be increasingly integrated into finance, trade and investment policies in support of the Sustainable Development Goals. 53. The follow-up and review of the implementation of the Goals provide a solid basis for assessing the progressive realization of the right to development. Devising indicators to measure and serve as a tool for achieving the Goals, in particular the collection and disaggregation of data, must be based on human rights principles and standards. 54. Assessment of the progress in the implementation of the 2030 Agenda can provide complementary information to the human rights mechanisms, including the Working Group on the Right to Development, for their assessment of progress in the realization of human rights, including the right to development. At the same time, recommendations made by the Working Group and other human rights mechanisms can provide useful information for the Financing for Development follow-up and for the High-level Political Forum assessment of progress in the implementation of the 2030 Agenda. 55. The Guiding Principles on Business and Human Rights and the principles for responsible contracts38 provide a solid basis for framing and directing private-sector engagement in the implementation of the 2030 Agenda and the Addis Ababa Action Agenda. 56. Efforts of civil society and national human rights institutions aimed at ensuring that all human rights, including the right to development, are respected in the implementation of the 2030 Agenda should be encouraged and supported. 37 38 See A/HRC/33/45.
