In 2007, the United Nations initiated a multi‐year renovation of its New York City headquarters, the Capital Master Plan (CMP). The campus-wide renovation, the most extensive since the campus was built in the 1950s, meets LEED Gold criteria, with the Secretariat tower achieving LEED Platinum certification. However, the decision to retrofit rather than demolish the existing buildings arguably achieved the greatest sustainability results―avoiding waste, reusing materials, and keeping tons of carbon dioxide out of the atmosphere.

To better understand the quantity of these savings, Michael Adlerstein, the Assistant Secretary-General and Executive Director for the UN Capital Master Plan, led a study to assess the carbon-saving value of the structures that were retained. The results of this study not only shed light on the magnitude of the savings, but also highlight the value and urgency of building reuse and renovation in reducing global greenhouse gas emissions. Join us for a discussion with Michael Adlerstein, John Amatruda and Kris Baker on the findings from this groundbreaking study.
