Meet Tom Vilsack

As former U.S. Secretary of Agriculture and a longtime champion for rural America and renewable fuels, Tom Vilsack will share insights on the foundation that helped pave the way for today’s 45Z opportunities. His keynote, “Building the 45Z Foundation,” will explore the policies, partnerships, and long-term vision behind climate-smart agriculture, low-carbon fuels, and the growing role farmers play in the future of energy.

Currently serving as CEO of the World Food Prize Foundation, Vilsack previously served 12 years as U.S. Secretary of Agriculture and eight years as Governor of Iowa. Throughout his public service career, he helped position Iowa and the United States as leaders in biofuels, renewable energy, climate-smart commodities, and rural economic development. His leadership at USDA focused on creating new market opportunities for farmers through renewable fuel production, environmental markets, exports, and bio-based manufacturing — many of the same conversations shaping the future of Carbon Intensity and 45Z today.
