Algae Biofarms Technology as a Powerful Tool for Decarbonization at Scale with Robert Politzer
Episode 213
Friday, 17 April, 2026
In this episode of CarbonSessions, we welcome Robert Politzer of Green Street Global for a fascinating conversation at the intersection of real estate, finance, energy, and the climate crisis.Robert explains why buildings account for roughly 40% of global carbon emissions and why commercial real estate is such a critical part of the climate equation. He also shares his long journey as a green building pioneer, from early LEED projects and solar initiatives in New York City to his current work on profitable decarbonization.The conversation then turns to a bold new frontier: algae biofarms. Robert makes the case that algae could become a game-changing solution for carbon removal, clean baseload power, shipping fuel, aviation fuel, cattle feed, and economic development. He describes this as the “dawning of the age of algae” and offers a hopeful vision of how this technology could help countries like Brazil, India, and the U.S. reduce emissions while strengthening their economies.In this episode, we discuss:Why Robert prefers the term climate crisis over climate changeWhy buildings and commercial real estate matter so much in decarbonizationHow Local Law 97 in New York City is reshaping building emissionsWhy profitable decarbonization is essential for business adoptionHow algae biofarms work and why they may outperform conventional carbon captureThe potential of algae-based oil for power generation, shipping, and aviation fuelThe value of algae byproducts like cattle feed, fish feed, and biochar fertilizerWhy Robert believes algae could become one of the most important climate solutions of our timeKey takeawayThere is still room for hope. While the climate crisis is real and urgent, transformative solutions are emerging, nd algae may become one of the most powerful tools we have for decarbonization at scale.About Robert PolitzerRobert Politzer is the founder of Green Street Global and a longtime green building pioneer working at the intersection of sustainability, commercial real estate, and climate solutions.📩 Contact: robert@greenstreetglobal.com 🔗 LinkedIn: Robert Politzer 🌐 Green Street Global / Myko Global----- Featuring Carbon Almanac Contributors Leekei Tang and Brian Tormey.Leekei is a fashion business founder, a business coach, an international development expert, and podcaster from Paris, France.
