What if decarbonizing a building didn’t cost money, but increased NOI, raised asset value, and reduced operating expenses, while staying compliant with the next wave of carbon laws?
And what if the fuel replacing petroleum isn’t solar or wind, but algae oil that can plug into existing global infrastructure?

Commercial real estate is entering a new era where carbon is no longer a philosophy, it’s a financial liability. In this episode, Robert Politzer, Founder and CEO of Green Street Global, breaks down how property owners can turn decarbonization mandates into a profit engine.

We cover Robert’s 28-year journey from pioneering green building projects in NYC to building a platform that combines cost-savings audits, vetted vendor marketplaces, and curated financing to deliver building upgrades with zero net cost. Then we go deeper into the idea that blew our minds, algae biofarms producing crude algae oil that can power generators, create renewable aviation and shipping fuels, and use existing petroleum infrastructure.

If you’re an owner, operator, investor, or developer trying to understand where regulation, NOI, and climate tech are headed, this one will sharpen your edge.

Robert Politzer is the Founder and CEO of Green Street Global, a climate tech company helping commercial property owners decarbonize buildings while cutting operating costs, increasing NOI, and improving asset value, often with no out-of-pocket cost. He has been a pioneer in green building for nearly three decades, founded one of New York City’s early green building firms, and has chaired multiple sustainability initiatives including the New York State Sustainable Business Task Force and the Manhattan Chamber of Commerce Green Buildings Committee. Today, Robert is building an AI-powered platform he calls DeCarb IQ, and exploring algae-based fuels as a major driver of scalable, profitable decarbonization.
