A/HRC/29/28 address this gap, aimed at developing practical guidance and good practice models for public authorities to integrate human rights due diligence procedures and requirements when purchasing goods and services from the private sector.40 As emphasized at the 2014 corporate social responsibility round table discussions, collaboration is essential to reach a critical scale. Members of the United Nations system can play a role in supporting developments towards more State action and aligning multilateral frameworks for public procurement with the Guiding Principles. Among the opportunities with potential for contributing to reaching greater scale, both UNCITRAL guidance for procurement and infrastructure projects and WTO discussions on government procurement could and should make reference to the Guiding Principles and take note of emerging tools and good practices. C. Financial institutions 1. World Bank Group 43. In the financial sector, the World Bank and its private-sector lending arm, the International Finance Corporation, is another key player within the United Nations system for enabling alignment with the Guiding Principles. The Corporation has already incorporated elements of the Guiding Principles into its social and environmental sustainability framework, updated in 2012.41 The current review of the World Bank’s Environmental and Social Framework42 offers a further opportunity for integrating key elements of the Guiding Principles to prevent and mitigate the risk of adverse human rights impacts related to the Bank’s lending activities. 44. It was stressed in a joint open letter to the World Bank President by several special procedures mandate holders, including the Working Group, 43 that the Bank’s safeguard standards should be premised on a recognition of the central importance of respecting and promoting human rights in order to respond to the challenges of the twenty-first century. Moreover, it was stated that, consistent with international law, with its own obligations and with those of its member States, the Bank should acknowledge the relevance of human rights in its overall programme objectives and incorporate human rights due diligence into its risk management policies. Similar recommendations have been made with respect to regional and national financial institutions. 44 www.ohchr.org/Documents/Issues/Business/ForumSession3/ParallelEvents/ICAR_DIFI.pdf; and Institute for Human Rights and Business, State of Play (see footnote 41), chap. 6. 40 See International Corporate Accountability Roundtable (ICAR) and the Danish Institute for Human Rights, International Learning Lab: Procurement and Human Rights (2015, forthcoming); ICAR, “Turning a blind eye?
