The transition to a circular economy is an urgent necessity to foster resilient, sustainable economic growth while reducing resource dependency. This session will examine how by harmonizing a range of existing circular economy guidelines, we can enhance clarity and consistency to facilitate scalable private investments. The harmonization aims to eliminate confusion, support alignment, and empower financiers to better recognize opportunities, track market trends, and catalyze investment growth. Additionally, this session will bring together key stakeholders in the development community to collectively unlock private investment toward a thriving circular economy.
