Climate change is here and District residents are already feeling the effects of hotter summers and more extreme weather. The energy used in buildings accounts for 71 percent of the District of Columbia’s greenhouse gas emissions. For the District to reach its ambitious climate goals as stated in its sustainability plan, it must move quickly to significantly reduce emissions in order to become the “the healthiest, greenest, and most livable city in the nation by 2032.” Even though the Hub is operated independently of the District government, the Hub aims to fundamentally transform the definition of “business as usual” and to make the District a model for a sustainable, market-based approach to climate action by both supporting those who are new to concepts and principles of sustainable buildings and by encouraging the market leaders to continue to push harder and share their stories.
