Biography

Maria Lettini is the Chief Executive Officer of the US Sustainable Investment Forum. She joined US SIF in May of 2023 and brought with her notable capital markets experience. She is an innovative leader within the field of sustainability and finance and is recognized for building meaningful partnerships across the value chain of global institutional investors, corporates, policymakers, multi-national organizations, and other related stakeholders to address some of the world’s most critical, and financially material, environmental, social challenges. 

Most recently, Maria led the FAIRR Initiative. During her six years at FAIRR, she and her team ambitiously drove the narrative around the risks and opportunities in the global protein supply chain with the aim of directing capital towards a more sustainable and equitable food system. Under her tenure, the FAIRR investor network grew to over $70 trillion in combined assets and FAIRR’s expert research on climate, biodiversity, anti-microbial resistance, and other risks reframed the narrative on animal agriculture and sustainable protein.  

Prior to joining FAIRR, Maria worked for the UN-supported Principles for Responsible Investment (PRI) where she cultivated and expanded the global investor network, managing the PRI’s Signatory Relations strategy and raising awareness of material ESG issues with institutional investors across the world.  

Maria started her career in global finance and capital markets, working at both J.P. Morgan and Deutsche Bank. She has served on the Sustainability Accounting Standard Board Standards Advisory Group. She is also a member of the Intentional Endowment Network’s (IEN) Steering Committee. 

Maria is based in Washington DC but has lived and worked in San Francisco, New York, Madrid and London. She holds a MA (Distinction) in Environment, Politics and Globalization from King’s College London and a BA in International Business, Latin American Studies and Spanish from San Diego State University.
