John Stewart

John Stewart is a senior leadership gifts officer at WBUR, Boston’s NPR, where one of his leading responsibilities is resourcing WBUR’s climate and environmental reporting locally and nationally. Since joining staff, he’s completed a certificate in applied sustainability through MET’s Urban Affairs program and is currently pursuing a MA in earth and environment. Some of his research interests include the tensions between affordable housing, migration, and climate policy at the city-level, as well as the relationship between rising authoritarianism, disinformation and climate progress.

Prior to WBUR, after being trained in grassroots organizing at Green Corps, John worked for more than a decade as a grassroots organizer, campaign director, and resource mobilizer for Corporate Accountability, a global human rights and environmental organization based in Boston. There, he worked on advancing the human right to water, a global public health treaty on tobacco control, and supported the launch of an initiative to protect the UNFCCC from the undue influence of the fossil fuel industry.

In his spare time, he’s wrangling his two young children with his wife Miriam in Roslindale, listening to podcasts, appreciating good storytelling, or connecting with family in his native Texas. Recently he started healing his relationship with piano and wrote about it for WBUR’s Cognoscenti Ideas page: https://www.wbur.org/cognoscenti/2025/06/13/piano-lessons-fatherhood-fathers-day-john-stewart
