Developing countries face the dual challenge of meeting rapidly growing energy demand while also scaling clean energy to avoid dramatic increases in carbon emissions. But financing all of those clean energy projects can be tough.

Emerging and developing economies need clean energy investments. Researchers estimate that they will need anywhere between $1-2 trillion per year for the next 30 years to reach net-zero emissions by 2050.

Most of that capital will need to come from the private sector. Multilateral development banks are working to fill the gap and catalyze private finance. But they still have to work through unique financial, policy, and technical challenges in emerging and developing economies.

So what are these barriers? And how do we overcome them to mobilize more capital for clean energy projects across the developing world?

This week, we’re re-running host Jason Bordoff’s interview with Mafalda Duarte. Mafalda is the CEO of Climate Investment Funds, one of the most ambitious efforts to finance clean energy projects in developing and middle-income countries. 

In September, Jason and Mafalda discussed opportunities for financing the clean energy transition in emerging economies—including an ambitious new effort to phase out coal in parts of Africa and Asia.
