Aemetis, Inc

Aemetis, Inc. is a renewable fuels and renewable natural gas company headquartered in Cupertino, California, founded in 2006. It operates production assets that convert agricultural inputs and wastes into low- and negative-carbon transportation fuels and related co-products. The company’s current operating segments include a California ethanol plant in Keyes, California, a California dairy renewable natural gas (RNG) business that sells RNG and associated environmental credits, and an India biodiesel business centered on the Kakinada plant. Its economics are closely tied to commodity spreads (feedstocks vs. fuel prices) and to policy-driven credit markets such as LCFS credits and D3 RINs.
