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.
Projects (7 of 15)
Research
Published research in journals from Nature, Science, and PNAS to field journals across several disciplines—all focused, in one form or another, on the space from climate risk to climate tech, with finance and policy as the fundamental drivers. Plus: current working papers.
Teaching
I (co-)teach Business and Climate Change, the most popular elective at Columbia Business School taken by 500 of 800 MBAs each year. I also teach Climate Policy, Climate Risk, and a travel course on Green Industrial Policy in Europe. (All are offered in the spring term, and most open via regular cross-registration channels.)
Columns
My monthly, globally syndicated column for Project Syndicate, translated into a dozen languages, and my earlier bi-weekly Risky Climate column for Bloomberg Green.
Geoengineering: The Gamble
"An important read." (The Sunday Times) — "A stark warning." (The Guardian)
Climate Shock
Read the NYT op-ed, the infamous pop quiz, our Salon feature, or Foreign Affairs and Atlantic essays. Watch the TEDx talk: “From Climate Shock to Geoengineering.”
Climate Knowledge Initiative
Columbia Business School initiative with the mission to conduct rigorous techno-economic analyses and turn them into actionable, business-relevant insights.
Audio & Video
Audio and video of radio and TV appearances, recorded talks, and other clips.
