New York Office


The Full Story


Starting out in 1998 by providing environmental remediation services, GreenStreet of New York Inc. grew into a General Contracting firm that specialized in high-performance green building. Some of GreenStreet’s most notable leading-edge construction and consulting projects included: the Mark Twain House Education & Visitors Center In Hartford, CT which was the first LEED Certified Museum in the US; the townhouse at 126 Ft. Greene Place in Brooklyn which was the first green townhouse project in NYC; Marmaduke Forster House which was the first LEED Certified Office building in Westchester County, NY and the Green Canteen restaurant in Brooklyn, which was the first LEED Certified restaurant in NYS. As the next step in our growth and evolution, we included commercial Real Estate Listings, Development and Consulting services for the past 5 years with a focus on high-performance and innovative projects. The model for our Smart Building Program was to apply it to our own development projects to optimize their energy and financial performance while offering the program on a consulting basis to other Developers.

In 2019, NYC passed Local Law 97, otherwise known as the Climate Mobilization Act, which established aggressive carbon emission reduction mandates with stiff fines for noncompliance. As the most aggressive Carbon Emission reduction Law in NYC’s history, we determined that nothing short of world-class, Global Real Estate Innovation Hubs were necessary to turn a massive legislative liability into a huge opportunity for Property Owners, Developers and Impact Investors. Thus GreenStreet NYC became GreenStreet Global, a network of Innovation Hubs with the singular mission of making it profitable to lower Co2 emissions from Commercial buildings.



GSG is building a network of Real Estate Innovation Hubs with a Mission of making it profitable to lower Carbon emissions from commercial buildings. Our Solution for fulfilling this Mission includes a vertically integrated process that begins with cost savings strategies and proceeds into zero-net cost Building Upgrades with 100% financing, where we lower Operating Costs and Carbon emissions while increasing the building's NOI and Valuation.  To fully monetize the profitability of our Upgrades, GSG provides Value Add Brokerage services in partnership with eXp Commercial where we sell the building at a higher valuation, then invest those Capital Gains into a new building through a 1031 Exchange and apply our Upgrade to the new building.  To enhance the effectiveness of our Upgrades, GSG is building the following capabilities:

  • Given the scope and complexity of building decarbonization, GSG is building an AI-driven proprietary App that will simplify, streamline and automate the entire process.  

  • GSG is growing a global Vendor Marketplace and virtual Vendor Tradeshow that will feature leading-edge Cleantech and Proptech firms from around the world that will allow for comprehensive turn-key solutions to full compliance with all Local, State and Federal Carbon emission reduction Laws.  

  • GSG continues to expand its extensive finance network that can provide 100% financing of all soft and hard costs which includes numerous green financing options including C-PACE financing and Green Bonds issued by Scandanavian Banks. 

  • And our ongoing Media Program will provide information and updates on Decarbonization Legal Mandates along with interviews with our Vendors and Case Studies that we will follow through their progress of completion.



The singular mission of GreenStreet Global is making it profitable to lower carbon emissions in commercial buildings.
