A/HRC/16/62 a certain point, while the legal gap concerning cross-border movements linked to environmental factors and climate was recognized, as stressed by the Office of the United Nations High Commissioner for Refugees and the International Organization for Migration. 52. Human rights mechanisms, including the treaty bodies, special procedures and the universal periodic review, were highlighted as an essential tool for early warning and facilitating the channelling of cooperation, therefore complementing the scientific calls to address the challenge of climate change. 53. The challenges of climate change to development and the threat to reverse the gains made towards the achievement of the Millennium Development Goals were highlighted, in particular with regard to Goal 1 on the eradication of extreme poverty and hunger and Goal 7 on environmental sustainability. 54. The right to education and the need for access to information, meaningful public participation, transparency and accountability were emphasized as a basis for the enjoyment of human rights, including the right to a sound environment or sustainable development. 55. The human rights-based approach calls for a focus on sound governance and accountability mechanisms, stressing both procedural and substantive rights. Accessible, transparent and effective accountability mechanisms should be in place, leading to effective remedies. The justiciability of economic, social and cultural rights was recalled, as was the fact that responsibility for achieving economic, social and cultural rights was not exclusively on the States concerned but also borne by non-State actors including the private sector, and other countries and the international community. 56. Transfer of technology, increased use of information and communication technologies, sharing and managing of knowledge, lessons learned and good practices, capacity-building and financial support can and must play a crucial role in addressing climate change, while promoting sustainable development and the achievement of human rights. 57. The current market approach to finding solutions to climate change was viewed as not wholly appropriate or fair, especially towards the countries or communities that are dealing already with the negative impacts of climate change. Nevertheless, with the appropriate safeguards, “green economy” instruments could be a potential tool to make economic actors aware of the environmental impact of their activities and of the services provided by the ecosystems with a view to ensuring better social returns and ecological benefits. 58. Some concerns were expressed with regard to market-based mechanisms for climate change, such as the REDD+ mechanism, which could be seen as a commoditization of forests, ineffective in preserving global forest stocks (as it would likely apply to only half of current forests) and lacking the effective involvement of indigenous peoples and local communities in REDD+ development. 59. There was a call for a national and global system allocating benefits and costs, ensuring that polluters pay and ensuring equity and non-discrimination. 17
