Tara Brown
Jack Henry Associates, Senior Director of Corporate Responsibility
“Berry Impact Consulting has helped turn our long-term sustainability goals into a practical, department-level roadmap. He’s moved us away from broad corporate targets toward a model of real accountability, giving our individual teams clear annual milestones to hit. By quantifying the financial risks associated with our footprint and providing a data-backed menu of mitigation options, he’s given us the tools we need to make informed, budget-conscious decisions about our climate impact.”

Senior Director
“Working with Berry Impact Consulting and Carter has been a truly positive experience. His creative problem-solving and analytical thinking helped us see new ways to understand the impact of sustainability professionals. He took the time to deeply understand our needs and challenges and developed an approach that was well aligned with our goals. I’ve especially valued working with him as a thought partner. One chance conversation with him helped me gain the confidence to take on an ambitious research project we ultimately collaborated on, as he helped me see that a complex question about program impact I wanted to answer was, in fact, possible to tackle. Carter also engages with warmth and eagerness, which made the entire process honest, collaborative, and productive. I highly recommend Berry Impact Consulting to anyone looking for a consultant who feels like a genuine partner.”

Impact Advantage, Head of Impact
“I felt fortunate to work with Berry Impact Consulting during an influx of research and impact valuation work at our agency. From our first discussion, it was clear he deeply understood our clients’ needs and brought the technical expertise and strategic mindset to recommend thoughtful approaches, outline trade offs, and guide collaborative decisions. Carter has a rare combination of skills—technical depth, clarity, reliability, and strategic insight. He consistently delivered high quality outputs on time or ahead of schedule, engaging at exactly the right level of detail. His leadership in developing the first value factors for environmental impact pathways for IFVI (now part of Capitals Coalition) reflects his strong position in the impact valuation field. Working with Carter has been a joy. I highly recommend him to anyone seeking confident direction and high quality sustainability or impact assessment work. ”
