Chief Sustainability Officer

Matt O’Malley serves as the first-ever Chief Sustainability Officer at Vicinity, where he leads the company’s ambitious decarbonization strategy and oversees its transition to carbon-free operations. He joined Vicinity in January 2022, following over a decade of public service on the Boston City Council, where he served as President Pro Tempore.

During his 11-year tenure on the Council, Matt was a driving force behind some of Boston’s most impactful environmental policies. He championed bold net-zero carbon building standards, expanded community choice energy, eliminated gas leaks and single-use plastic bags, and introduced curbside composting to divert organics from landfills. He also authored the landmark Building Energy Reporting and Disclosure Ordinance (BERDO), which has required large buildings to report their energy and water usage since 2013 and now empowers the city to set individual carbon targets. A testament to his popularity and effectiveness, he earned more votes than any district city councilor in Boston’s history.

With more than 18 years of leadership across public, private, and advocacy sectors, Matt is widely regarded as a visionary in environmental policy and climate action. He holds a bachelor’s degree in Political Science and English from The George Washington University.

Matt continues to shape sustainable development and climate solutions through his roles on the Boston Planning and Development Agency Board, as Chair of the Environmental League of Massachusetts Board, and as a Trustee of the Boston Latin School Association. A dedicated community member and avid runner, he has completed the Boston Marathon in support of organizations including Habitat for Humanity Greater Boston, Project Hope, and the Dana-Farber Cancer Institute. He lives in West Roxbury with his wife, Kathryn, and their daughter, Margot.
