We are NGOs, social enterprises, intermediaries, funders and other social change innovators, collaborating in this urgent moment to achieve the Sustainable Development Goals (SDGs). We live in a unique era of human progress. Extreme poverty, malnutrition, violence, and infectious disease have plummeted, while life expectancy, literacy rates, and electricity access have soared. Yet, severe inequalities in income, health, education, and representation disadvantage billions around the world. Meanwhile, humanity’s growing ecological footprint is threatening many of the natural systems we all depend on—such as climate, oceans, land, biodiversity, and fresh water—which are nearing irreversible tipping points. These crises often intersect, creating conditions ripe for instability and conflict.
