Green Impact Exchange Appoints Maria Mahl as Chief Product Officer
Mark Segal
December 3, 2025
Sustainable investing-focused capital market exchange Green Impact Exchange (GIX) announced today the appointment of Maria Mahl as Chief Product Officer, responsible for leading the execution of GIX’s recently announced product roadmap.
Founded in 2022 by former NYSE executives, including CEO Daniel Labovitz, former head of regulatory policy at the NYSE, and Chief Operating Officer Charles Dolan, former Executive Floor Governor at the NYSE, GIX aims to be the first national securities exchange in the U.S. dedicated to the emerging global green economy, listing companies that make binding commitments to set, implement, measure, and achieve sustainability goals, and to provide investors with transparency about their progress.
The new appointment follows the approval earlier this year by the U.S. Securities and Exchange Commission (SEC) of Green Impact Exchange’s application for registration as a national securities exchange, enabling the GIX to launch as the first sustainability-focused stock market in the U.S. The company aims to launch its traditional listings exchange in mid-2026.
Mahl joins GIX from sustainability data and technology company ESG Book, where she served as Partner and Head of ESG Solutions USA. Prior to joining ESG Book, she held leadership roles at Arabesque AI Asset Management and the Clinton Global Initiative.
Dan Labovitz, CEO of GIX, said:
“Maria’s appointment is a significant win for GIX. She brings not only an intricate knowledge of the climate transition and sustainable finance space, but also the entrepreneurial drive of someone who has successfully navigated the journey from seed stage to IPO. Her deep technical background in AI and data standards ensures our products will meet investors’ rigorous demands. With Maria spearheading our product roadmap, GIX is ready to redefine how markets allocate capital toward sustainability.”
In her new role, Mahl will oversee GIX’s planned product suite which includes regulated exchange-traded products for carbon credits, a digital platform integrating blockchain-enabled tokenized assets into traditional market structures, a green economy index licensed to asset managers and ETF issuers, and a listing tier for shares of companies demonstrating material environmental commitments.
Mahl said:
“The sustainable finance ecosystem is entering a defining era, with $30 trillion of capital poised to reshape the global economy. GIX is the only exchange built from the ground up to ensure that this capital is deployed with integrity, transparency, and impact. Having built data and technology platforms that bridge the gap between regulatory standards and commercial viability, I see GIX as having the necessary infrastructure to scale this market. I am thrilled to lead GIX’s product strategy to bring groundbreaking sustainability-focused solutions—from carbon credit instruments to tokenized assets—into mainstream markets. Together, we will empower investors and companies to drive the growth of the green economy.”
