Episode notes

Climate models are so important because climate itself is a complex phenomenon, and one that is inherently about the things that we don't know. So much of our current forecasts and models that exist for other types of risks are in need of upgrade or amendment when thinking about climate. And that's really where models come in to give us some of those insights to help us also deal with those uncertainties that I mentioned.

The U.N. climate conference known as COP27 kicks off next week. Adaptation to a changing climate will be an important part of the talks.

In this episode of the ESG Insider podcast, we look at how companies and investors are using climate modeling to measure and manage the future financial impacts of climate hazards such as wildfires, drought and flooding. According to a new S&P Global Sustainable1 dataset, 92% of S&P Global 1200 companies will have at least one asset highly exposed to physical hazards by the 2050s under a business-as-usual high-emissions scenario.

We speak to David Carlin from U.N. Environment Programme’s Financial Initiative, where he leads the Task Force on Climate-Related Financial Disclosures (TCFD) program for banks and investors.

We also talk with our colleague Steven Bullock, Global Head of ESG Innovation and Solutions at S&P Global Sustainable1, who says the increasing demand for climate data created with the help of climate models reflects the growing recognition that ESG is a driver of corporate business value and financial risk.

And we hear from Alban Pyanet, partner at consultancy Oliver Wyman, about how climate modeling helps financial institutions manage climate risk.
