A/71/398 Commission agreed in March 2016 to use this framework, which includes a total of 230 indicators, as a practical starting point. Mindful that the set of indicators may lack sound methodologies and significant country coverage, the Expert Group intends to regularly update and refine the indicators as they evolve and new forms of technology will allow for better and more complete data collection. 46. The Millennium Development Goals contained no targets or indicators relating to violence. By comparison, the 2030 Agenda contains several targets and indicators on the magnitude of the various forms of violence against women. 47. Gender-based violence is therefore acknowledged in the 2030 Agenda as a major obstacle to social and economic development and to the achievement of the Sustainable Development Goals. Indeed, violence against women undercuts sustainable development by obstructing women’s participation in development and undermining the goals of development. The integral connection between violenc e against women and development is therefore clearly made in the 2030 Agenda. 48. The implementation of the 2030 Agenda provides a new opportunity to accelerate progress in achieving gender equality, the empowerment of women and girls and the elimination of violence against women through, among other things, improving the collection of data on violence against women in general and femicide in particular. The collection of reliable and comparable data is needed to prevent such violence. Data requirements to effectively monitor the Goals for women and girls will be substantial and significant investments and capacity -building will have to be made to fill the data gaps that have been identified. 49. There is an opportunity to improve the data requirements of the Goals, which will also provide an impetus for increased cooperation among the relevant United Nations agencies, namely, the United Nations Entity for Gender Equality and the Empowerment of Women (UN-Women), the Office of the United Nations High Commissioner for Human Rights and UNODC, but also human rights mechanisms, such as the Special Rapporteur on violence against women, its causes and consequences, the Working Group on the issue of discrimination against women in law and in practice and the Committee on the Elimination of Discrimination against Women. 50. The Special Rapporteur believes that data on femicide should be seen as an important indicator for the elimination of violence against women. 51. The Under-Secretary-General and Executive Director powerfully said at the time of the adoption of the 2030 Agenda: of UN-Women Data on their own will not change lives, but we will not change lives without them. With the right metrics and illuminating information, we can inform policies, check on progress and hold leaders accountable if they fall behind on their commitments. We need 2030 to be the point when the lives of girls and women have been changed irreversibly, sustainably and substantively for the better. 52. The message of the 2030 Agenda of leaving no one behind is key to reaching out to the most marginalized women, including women who are victims or at risk of violence, including in its most extreme lethal form. 16/24 16-16456
