According to the United Nations, the world needs an extra $4 trillion every year to tackle some of the world's biggest challenges - ending poverty and hunger, fighting climate change, and reducing inequality.
These are part of 17 goals agreed by nearly every country, called the Sustainable Development Goals (SDGs). The plan is to hit these targets by 2030.
But we're falling behind. One big reason? There just isn't enough consistent funding to make real progress.
That's why world leaders, economists, and other decision-makers are meeting at the end of this month in Sevilla, Spain, for a major event called the Fourth International Conference on Financing for Development. It's being called a "once-in-a-decade opportunity" to rethink how the world pays for sustainable development.
