Bryan and his wife, Lisa, operate a grain and livestock farm which includes 1,800 acres of tillable land and a 2,400 head beef cattle feedlot in Scott County, Iowa, USA. The Sievers are enthusiastic environmental stewards of the land that has been in the family for over 150 years. They have been actively involved in implementing many conservation practices on their farm. In 2022, the Sievers planted thirty-seven acres of perennial prairie on their farm that will enhance the sustainability of their farming operations while providing multiple ecosystem services to the surrounding community. In 2013, they commissioned their 1.0 MW combined heat and power (CHP) anaerobic digester system. This biomethane and renewable energy system processes all of the beef cattle manure plus additional sources of food waste and biomass from winter-hardy cover crops and native perennial prairies. They return all of the rich, pathogen-free, and nutrient-dense soil amendments produced by their digesters to their farmland in the form of nitrogen, phosphorus, potassium, sulfur, and organic matter. In 2022, Bryan and Lisa partnered with Roeslein Renewables (https://roesleinalternativeenergy.com/) to form a new company called Horizon II.  This new company produces renewable natural gas, from state-of-the art technology, which is injected into a pipeline for use as liquid transportation fuel. The injection of renewable natural gas into the national pipeline grid is the first of its kind in the United States from beef cattle manure. In February 2025, Roeslein Renewables, a leader in alternative energy and conservation, and Horizon II were awarded ISCC PLUS and ISCC EU certifications for biomass feedstocks used in renewable natural gas (RNG) production. This is the first ISCC certification for biomass-based crop residues, including cover crops, processed for clean-burning RNG.

In October 2022, RAE, Sievers Family Farms, and thirteen partners were awarded an $80 million grant from the USDA’s Partnerships for Climate-Smart Commodities program. Bryan served as Director for this innovative five-year program for the first two and a half years (until April 2025). Here is a link to the USDA web site that describes the grant titled Horizon II: A Climate-Smart Future for Corn, Soybean, Livestock, and Renewable Natural Gas Production: https://www.usda.gov/climate-solutions/climate-smart-commodities/projects.​​​​​​​  Here is a link to Horizon II’s website called Prairie Prophets: https://prairieprophets.com/.

In March 2022, Bryan was chosen to become Director of Government Relations for Roeslein Alternative Energy and currently serves in that capacity. Bryan received his degree in Agricultural Business in 1982 from Iowa State University. His past experiences include being a 3-year letterman on the Iowa State University baseball team, leadership roles in the Iowa Farm Bureau, a graduate of Leadership Iowa, serving two terms in the Iowa Legislature (one term in the Iowa House and one term in the Iowa Senate) and served as Chair of the Iowa Economic Development Authority’s Biomass Conversion committee.  He currently serves as Vice-Chair on the American Biogas Council (ABC) Board of Directors. Bryan co-chairs the Agriculture Committee and Policy Committee for the ABC. Bryan also served on Iowa Governor Kim Reynolds’ Carbon Sequestration Task Force. He also serves as Co-Chair of the Iowa Smart Agriculture initiative. Bryan and Lisa have two children and six grandchildren.

Veronica serves as Director of Environmental Science for Clean Fuels Alliance America, where she leads the advancement of education and research on the climate and public health benefits of biobased diesel and sustainable aviation fuels. In this role, Veronica educates relevant stakeholders on the environmental benefits of clean fuels and works with industry to identify and execute on relevant research needs. This work ensures feedstock and producer members’ products are accurately assessed for their climate benefits and are appropriately accounted for in reporting by end users and policymakers.

Before joining Clean Fuels, Veronica served as Director of Environmental Affairs at Airlines for America, where she assisted in environmental advocacy activities relating to aircraft and airline operations. She was previously a Research Associate at ICF, where she supported the Climate Change and Stratospheric Ozone Protection Divisions for the U.S. Environmental Protection Agency.
