Chevron Renewable Energy Group (REG)

The roots of Chevron Renewable Energy Group go back more than two decades to when the company operated under the umbrella of West Central Cooperative in Ralston, Iowa. Chevron REG’s history parallels that of the biodiesel industry as a whole: when they made their first batch of biodiesel in 1996, the industry was still in its early stages, a niche market with a potential few foresaw. While Chevron REG’s leaders grew the company carefully and consistently by finding opportunity within challenges, they also advocated for the biodiesel industry as a whole, often working with competitors for the greater good. Today, Chevron REG is the largest biodiesel producer by volume in the United States — as well as a producer and supplier of many other products — and continues to contribute resources and leadership to biofuel advocacy groups worldwide.
