The future of climate finance
The trend is clear. So are the challenges. One key task is to de-risk capital investments to lower costs. This is where public climate finance must play its most critical role – not as charity, but as leverage.
I’m a climate economist at Columbia Business School and author of six books, including Climate Shock and Geoengineering: the Gamble. Here you find my research, teaching, writing, speaking, and current preoccupations squarely focused on climate risks and solutions.
