How Does AAG Screen its Investments?
By Antoinette WinklerPrins, AAG Council Treasurer
This is the fifth of a short series of perspectives by 2024-2026 Council Treasurer Antoinette WinklerPrins — a series designed to help illuminate some of the financial challenges a professional organization such as the AAG faces. In this column, she offers perspectives on the financial aspects of running the AAG Annual Meeting. Read previous columns.
Many nonprofit organizations care about where and how they invest the funds they have available for investment. Most organizations work with financial advisors and use mutual funds as a way of obtaining strong and consistent returns on their investment decisions. While it is a core obligation of the AAG to invest in such a way that it can support its programming and awards, nonprofit organizations also usually have strong missions, and usually seek to align their investment portfolio with their mission. One method of doing so is to use investment “screens,” a device that permits the investor to identify stocks that align with their core mission, and more importantly, to exclude investments that do not.
To manage its modest endowment, the AAG uses exclusively socially responsible screens known as ESG filters. ESG stands for “Environment, Social and Governance” and means that these screens select for investments in corporations that demonstrate concern about environmental issues, social justice, and ethical and transparent governance, and excludes investments in the fossil fuel industry, arms manufacturing, or occupied territories. This way the AAG investment portfolio aligns with AAG’s mission. The AAG has been 100% ESG invested since June 2022, working with its bank, Truist, through its Envestment PMC investment platform. This platform uses ESG screens from Morningstar Sustainalytics, which has conducted monitoring and research into ESG investing for more than 30 years. Clients such as the AAG select screens they wish to have applied to screen investments.
Truist offers a variety of different ESG screens, from which a maximum of three can be selected at any given time. In coordination with the AAG Finance Committee, the AAG Executive Director selected screens that screen out investments in fossil fuels and seek out the best-in-class choices for the environment. AAG also has chosen as its third screen, one that focuses on social justice, including attention to human rights and occupied territories around the world. We feel that these screens reflect the values of the organization, and all of AAG’s investments are now automatically pushed through these screens to generate a portfolio to ensure consistency with these values.
The AAG is constantly seeking to balance its needs for investment success while underscoring the desire to invest in ways that match its members’ values. By selecting screens that square with our mission, we can assure our members that we lead with our values in our investment portfolio. As part of the work of the Finance Committee, which I chair as AAG Treasurer, there is periodic review of the selected screens to ensure that they are functioning as intended.

Mirembe Ddumba is a junior studying Economics at Penn State University. She first became interested in geography during a Spring 2025 economic geography course, where she saw how maps and data could explain not just where things happen, but why communities grow and change the way they do. Using ArcGIS, she looked at how AI and shifts in different industries affect where people live and work, and realized that a map can sometimes tell a story better than pages of numbers. That interest led her to a Paragon Policy Fellowship, where she co-authored Charleston’s 2025–2027 flood-resilience plan and presented ideas to city leaders. She also co-created EcoGrow, a solar-powered smart farm with AI forecasting that won first place in a campus innovation challenge.
Samra McCullin is a fourth-year student at George Mason University majoring in Geography with a minor in GIS. Samra’s first introduction to the discipline was a human geography class that she took in high school, where she found passion in the intersection of social, environmental, and physical sciences. In her undergraduate coursework she is constantly surprised at how she is able to exercise both her creative and analytical strengths. The freedom of a multidisciplinary major has allowed her to explore many subgenres within geography, her favorites being tourism, transportation, and sustainable development. Following graduation in the spring, Samra intends to pursue her masters in Geographic and Cartographic Sciences, working towards a professional career in digital cartography. Samra feels lucky to have found geography as a career path so early into her academic journey and hopes that through her work as a Communities Support Intern for the AAG, she can help more people find purpose and belonging within the discipline.
