A/HRC/33/31 advocated for data disaggregation in line with the recognized grounds of discrimination, to capture progress in combatting inequalities, inequities and discrimination. OHCHR published the guidance note to data collection and disaggregation entitled “A human rightsbased approach to data: leaving no one behind in the 2030 Agenda”.25 28. OHCHR organized the signing ceremony for the Geneva Pledge for Human Rights in Climate Action, which was hosted by the Permanent Mission of Costa Rica to the United Nations Office and other international organizations in Geneva. The pledge calls for meaningful collaboration among national representatives in the human rights and climate change processes to inform climate action. OHCHR engaged in the negotiations of the twenty-first session of the Conference of the Parties to the United Nations Framework Convention on Climate Change, held in Paris in December 2015. OHCHR advocated the most ambitious climate mitigation target possible, demanded accelerated and equitable climate action and called for all such action to respect and protect human rights, including the right to development. The OHCHR “Key messages on human rights and climate change” (see annex II) served as the basis for this advocacy. 29. The High Commissioner issued an op-ed and press releases and called for, inter alia, limiting warming to no more than 1.5°C above pre-industrial levels, improved international cooperation to address climate change and the inclusion of strong human rights language in the operative part of the Paris Agreement. OHCHR submitted a paper entitled “Understanding human rights and climate change”26 to the twenty-first session of the Conference of the Parties in Paris, supported several special procedure mandate holders in their engagement in the negotiations, participated in multiple side events and organized a press conference on human rights and climate change during Human Rights Day. During the twenty-ninth session of the Human Rights Council, OHCHR organized a panel discussion on the impacts of climate change on the enjoyment of the right to health. Panellists, including the Director General of the World Health Organization and the Special Rapporteur on the right of everyone to the enjoyment of the highest attainable standard of physical and mental health, emphasized the need for a rights-based approach to climate action.27 30. As a result of this and other advocacy, the Paris Agreement is the first multilateral climate agreement of its kind to include explicit reference to human rights. The Agreement also contains the ambitious objective of limiting warming to below 2°C and pursuing efforts to bring it to 1.5°C. Other positive elements include references to the principle of common but differentiated responsibility and equity, commitments on climate finance, a new transparency framework, a mechanism for monitoring and ratcheting up climate commitments, strengthened cooperation on loss and damages and special provisions for least developed countries and small island developing States as well as vulnerable groups, gender equality and women’s empowerment.
