Nicola “Niki” Armacost has served as the mayor of Hastings-on-Hudson, New York, since 2019, and before that as trustee since 2009. As mayor, she has championed sustainability initiatives and built local resiliency to climate change. Under her leadership, Hastings is setting the pace for New York State’s Clean Energy Communities and Climate Smart Communities programs.
The municipality adopted the New York Stretch Energy Code; expanded financing for energy efficiency through Open C-PACE financing; passed a Low-Embodied Carbon Concrete Resolution; invested in EVs, alternative fuel infrastructure, and resiliency planning; promoted “buy local” initiatives; dedicated over 85 percent of municipal-owned open space as parkland; and supported local pollinator pathway initiatives.
Mayor Armacost is also the managing director of Arc Finance, whose mission is to link the fields of finance, energy, water, and sanitation. Arc’s financial institution partners have provided access to clean energy for over 4.5 million people in a range of countries, including Afghanistan, India, Nepal, Pakistan, the Philippines, Kenya, Uganda, Ghana, Nicaragua, and Haiti. Arc’s partners offer financing for distributed solar, rooftop solar, e-vehicles, as well as micro- and mini-grids. Previously, she worked at Women’s World Banking, a global microfinance network, and is an advisor to a number of companies focused on the off-grid energy space.
