Mark Kresowik

Mark Kresowik managed federal and international policy for the Carbon-Free Buildings program at RMI. The Carbon-Free Buildings program is ending reliance on fossil fuels to power and construct our built environment. In that role, Mark centered the leadership of those who most struggle to afford energy and housing in our communities, and advocated for quality, family-supporting labor for workers.


Mark came to RMI after nearly 15 years at the Sierra Club. Mark was one of the first staff members of the Sierra Club’s Beyond Coal Campaign, helping end the rush to build new coal plants, ramp up clean energy, support transition for workers and communities, and cut pollution and power generation from coal in half. Mark co-led Sierra Club’s national equitable building electrification and electric vehicle charging infrastructure campaigns, and managed staff and teams throughout the Northeast, mid-Atlantic, and Appalachian regions. He led Sierra Club’s engagement with the Federal Energy Regulatory Commission, regional electric market operators, the Regional Greenhouse Gas Initiative, and the Transportation and Climate Initiative.

Mark has previously served as an interim executive director of Iowa Interfaith Power & Light and on the boards of RENEW Northeast, the Sustainable FERC Project, and the Center for Global and Regional Environmental Research.
