Since the first CLF Regional Hub launched in Vancouver, Canada the fall of 2019, new Hubs have flowered around the world. Hubs are are convened by groups of CLF Community members to help interested professionals share best practices, discuss solutions, and spread the word about embodied carbon. Hubs initially arose without any particular guidance or strategic planning. However, this spontaneous growth was driven by a deep sense of urgency, and a profound desire to collaborate across our industry. By the spring of 2021, Regional Hubs had been initiated in 29 cities across the globe, from Boston to Bengaluru, from Omaha to Ottawa. In a sign of the potential for Hubs to accelerate change, Mayor of Pittsburgh recently signed an Executive Order for the City of Pittsburgh to develop a unified City-led deconstruction policy and establish a City-led pilot program utilizing deconstruction methods on City-owned condemned properties.
