Columbia University Sustainable Finance Seminars

 

SIRI leads the monthly (online and in-person) Columbia University Sustainable Finance Seminar. The working group sessions will focus on the identified pathways to consensus (including but not limited to system-level investing, fiduciary duty, and intergenerational equity) to drive forward the rewiring of the source code of capitalism and foster ecosystem-building. By doing so, SIRI provides an important institutional platform that brings together and fosters dialogue among a variety of key players from the public and private sectors, policy, and academia. 

Following each seminar, a report summarizing the key insights and discussion points will be drafted and shared with participants. These reports will also be posted on this webpage accessible to companies, investors, and educators around the world.

Please join us for these monthly discussions and participate in the Columbia University Sustainable Finance Seminars.

Co-Chairs: Caroline Flammer and Bob Massie

Taking Externalities into Account: Assumptions, Limitations, Pathways, and Integrating Opportunities

We are honored to be joined by two distinguished speakers:

Jeremy Nicholls, co-founder and former CEO of Social Value International, a global leader in advancing the measurement and integration of social and environmental value. 

James ('Jim') Hawley, co-founder and CEO of the Externality Investment Research Network (EIRN) and author of Moving Beyond Modern Portfolio Theory, who has been at the forefront of rethinking how externalities affect whole-portfolio outcomes, fiduciary duty, and system-level risk.

They will share insights into the assumptions and limitations of current approaches, outline suggested pathways for incorporating externalities, and discuss opportunities arising from these pathways.
