The United Nations calls its 17 Sustainable Development Goals "the blueprint to achieve a better and more sustainable future for all." With a target of achieving them by 2030, the goals are all interconnected and address the global challenges we face.

Goal 5 is "Gender Equality." As the UN puts it: "Gender equality is not only a fundamental human right, but a necessary foundation for a peaceful, prosperous and sustainable world."
