Carter Berry, Ph.D.
Founder & Principal Strategist
I'm an environmental scientist and sustainability strategist who works at the intersection of business, nature, and community. For over a decade, I've helped organizations understand their relationships with the planet, translate environmental impacts into business strategy, and build the case for why people and nature aren't just "nice to have", they're essential.
Before starting Berry Impact Consulting, I was the Environmental Impact Manager at the International Foundation for Valuing Impacts (IFVI), where I developed and deployed frameworks that quantify environmental costs in the language of currency and worked with organizations worldwide to implement them. I've worked with multinational companies, global consultants, data providers, and nonprofits to advance how we measure and act on impact analysis.
Previously, I spent a decade as a research scientist leading climate and nature research and mentoring emerging scientists. My interdisciplinary work integrated ecology, engineering, economics, and data science, resulting in more than 40 peer-reviewed publications.
I'm also committed to local action. I've led my city's Sustainability Advisory Committee, championed solar energy campaigns, volunteered in my community, and mentored students. While the scale of impact happens globally, each change happens locally by individuals showing up and helping out.
Education: Ph.D. Biology, Wake Forest University. B.S. Biology, B.A. Psychology, Minor in Chemistry, UNC Chapel Hill.
Marc Rosenfield
Sustainability Consultant
I'm a researcher, ecologist, and environmental scientist who turns complex environmental data into actionable results. Rigorous scientific analysis is challenging, but implementation is even harder; my skillset sits at the intersection of both.
Before joining Berry Consulting, I was the Environmental Impact Associate at IFVI and Environmental Technical Manager at Capitals Coalition. There I focused on methodology development for their Impact Accounting Standards. I used my quantitative, modeling, and report writing skills to develop impact standards for greenhouse gas emissions, water consumption, water pollution, waste, land use, and air pollution.
I built a varied occupational history before coming to the Impact Accounting world. I worked in carbon accounting for Nature-Based Solutions projects across the Americas, Africa, and Asia. I also had an extended academic history in the field of ecology, with 8 peer-reviewed publications in community ecology, botany, and biogeochemistry. Along with my ecological research, I developed low-cost CO2 flux sensors that were distributed across Washington D.C. to understand changes in carbon emissions in the city during COVID shutdowns, with notable deployments at the United States Capitol Building, U.S. Arboretum, Smithsonian Castle, Anacostia Museum, and more.
Outside my consulting work, I am an avid hiker and musician.
Education: M.S. Biology, The George Washington University. B.S. Environmental Science and Policy, Chapman University, with a Minor in Violin Performance.
