ESG & Sustainable Investing Editor
Fiona Walsh is a Chartered Financial Analyst with a SASB FSA (Fundamentals of Sustainability Accounting) credential and 10 years analyzing ESG funds, impact investments, and sustainable portfolios. She was an ESG research analyst at MSCI for five years, where she rated thousands of companies on environmental, social, and governance metrics. Fiona later joined US SIF (Forum for Sustainable and Responsible Investment) as a policy research director. Her work helps investors align returns with values without sacrificing performance.
Rating thousands of companies at MSCI taught Fiona how inconsistent ESG scoring can be between providers — the same company can rank in the top decile on one ESG scale and the bottom half on another, depending on methodology. She uses that experience to help MONEYlume readers look past a single ESG label and check what a fund is actually screening for before assuming it matches their values.
Her policy work at US SIF focused on shareholder advocacy and proxy voting trends, giving her visibility into how asset managers use — or don't use — their voting power on climate and governance resolutions. Fiona now writes about expense ratios, greenwashing red flags, and how to compare sustainable fund options against their conventional benchmarks on a level, after-fee basis.
