Nature of Business, Financial Condition and Basis of Presentation	Nature of Business, Financial Condition and Basis of Presentation Nature of business. Gevo, Inc. (Nasdaq: GEVO) ("Gevo" or the "Company," which, unless otherwise indicated, refers to Gevo, Inc. and its subsidiaries), a Delaware corporation founded in 2005, is a growth-oriented company with the mission of solving greenhouse gas emissions for those sectors of the transportation industry that are not amenable to electrification or hydrogen. The Company is focused on transforming renewable energy into energy-dense liquid drop-in hydrocarbons that can be used as renewable fuels, such as sustainable aviation fuel ("SAF") and other fuels and chemicals, with the potential to achieve a “net-zero” greenhouse gas ("GHG") footprint. The Company uses the Argonne National Laboratory’s GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) model (the "GREET Model") to measure, predict and verify GHG emissions across the life-cycle of its products. The “net-zero” concept means Gevo expects that by using sustainably grown feedstock (i.e., low till, no-till and dry corn cultivation), renewable and substantially decarbonized energy sources, drop-in hydrocarbon fuels can be produced that have a net-zero, full life cycle footprint measured from the capture of renewable carbon through the burning of the fuel. Gevo's primary market focus, given current demand and growing customer interest, is SAF. The Company believes it also has commercial opportunities for other renewable hydrocarbon products, such as (i) hydrocarbons for gasoline blendstocks and diesel fuel, (ii) plastics, materials and other chemicals, and (iii) renewable natural gas (“RNG”). Net-Zero Projects In early 2021, we announced the concept of “Net-Zero Projects” as a series of planned facilities to produce energy dense liquid hydrocarbons using renewable energy and our proprietary technology. The concept of a Net-Zero Project is to convert renewable energy (e.g., photosynthetic, wind, RNG, biogas) from a variety of sources into energy dense liquid hydrocarbons that, when burned in traditional engines, have the potential to achieve net-zero GHG emissions across the whole lifecycle of the liquid fuel: from the way carbon is captured from the atmosphere, processed to make liquid fuel products, and burnt as a fuel for cars, planes, trucks and ships. Our initial Net-Zero Project, Net-Zero 1 (“NZ1"), is located in Lake Preston, South Dakota, and is being currently designed to produce approximately 62 million gallons per year ("MGPY") of total hydrocarbon volumes, including 55 MGPY of SAF. Along with the hydrocarbons, NZ1 is being currently designed to produce approximately 475 million pounds per year of high-value protein products for use in the food chain and more than 30 million pounds per year of corn oil. Our products will be produced in three steps; the first step is milling the corn and the production of protein, oil, and carbohydrates, the second step produces alcohols using fermentation and the third step is the conversion of the alcohols into hydrocarbons. Renewable Natural Gas Projects Gevo's RNG project in Northwest Iowa ("NW Iowa RNG") is owned by Gevo NW Iowa RNG, LLC, and produces RNG captured from dairy cow manure. The manure is supplied by three local dairies that have over 20,000 milking cows in total with additional milking cows expected pursuant to agreements executed during the second quarter of 2022. Animal manure can be digested anaerobically to produce biogas, which is then upgraded to pipeline quality gas referred to as RNG. Gevo NW Iowa RNG, LLC sells the produced RNG to the California market through an agreement with BP Canada Energy Marketing Corp. and BP Products North America Inc. (collectively, "BP"). Luverne Facility Gevo's development plant in Luverne, Minnesota (the "Luverne Facility") was originally constructed in 1998 and is located on approximately 55 acres of land, which contains approximately 50,000 square feet of building space. Gevo may use the Luverne Facility in the future to prove our processes, process concepts, unit operations and for other purposes in order to optimize feedstocks and the processes used for producing hydrocarbons from alcohols. Currently, the activities at the Luverne Facility are minimized to care and maintenance, as the Company has shifted focus to the Net-Zero Projects. Basis of presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) along with the instructions to Form 10-Q and Article 10 of Regulation S-X assuming the Company will continue as a going concern. Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. These statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows of the Company as of, and for the nine months ended, September 30, 2022, and are not necessarily indicative of the results to be expected for the full year. These statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included under the heading “Financial Statements and Supplementary Data” in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The financial statements at December 31, 2021, have been derived from the audited financial statements as of that date. For further information, refer to our audited financial statements and notes thereto included for the year ended December 31, 2021 (the "2021 Annual Report"). Environmental Attribute Inventory. The Company generates D3 RINs Renewable Identification Numbers ("RINs") and Low Carbon Fuel Standard ("LCFS") credits (collectively, "environmental attributes") through the production of RNG used for transportation purposes as prescribed under the Renewable Fuels Standard program ("RFS"). The Company considers environmental attributes to be a distinguishable product that is generated as an integral component of the production process of RNG as the environmental attributes that are generated can be separated from the underlying commodity and may be sold independently from the RNG produced. As such, the Company considers environmental attributes to be a co-product of the production of RNG and accordingly allocates the costs of production based on the relative sales value of all revenue items for the NW Iowa RNG operations. Revenue is recognized on these environmental attributes when there is an agreement in place to monetize the credits at an agreed upon price with a customer based upon defined third party market prices and a transfer of control has occurred. Reclassifications. The Company reclassified certain prior period amounts to conform to the current period presentation. The reclassifications included the categorization of depreciation and amortization on the Consolidated Statements of Operations and had no impact on total revenues, total cost of goods sold, total operating expenses, net loss or stockholders' equity for any period.
