The Sustainable Development Goals were signed by 193 countries at the UN summit on Friday night. The event included speeches from Pope Francis and Malala Yousafzai, the Pakistani teenager who became a Nobel laureate after surviving a Taliban attack, and a performance by the pop star Shakira.
The 17 goals apply to all countries, rich and poor, and include 169 action targets that aim to tackle poverty, climate change and inequality for all people around the world.
They come at the end of more than three years of negotiations between countries.
