Preliminary Comments on Lark et al. 2022 RFS Study
This memorandum provides Net Gain’s preliminary observations regarding Environmental Outcomes of the US Renewable Fuel Standard published by Lark et al. (2022). The work described in this paper appears to be the...
Current Methods for LCA of Low-Carbon Transportation Fuels in the United States (2022)
Greenhouse gas (GHG) emissions drive climate change. In the United States, transportation is the largest source of GHG emissions. Petroleum products account for about 90 percent of U.S. transportation fuels, with biofuels,...
Environmental Outcomes of the US Renewable Fuel Standard: Lark Study
The Renewable Fuel Standard (RFS) specifies the use of biofuels in the United States and thereby guides nearly half of all global biofuel production, yet outcomes of this keystone climate and environmental...
Comments to EPA on 2020-2022 RFS Rule: Stillwater
1 2022 Potential Ethanol Production EIA lists the U.S. ethanol nameplate production capacity for 2020 at 17.38 billion gallons per year. How much of this ethanol production capacity can be used is...
Review of GHG Emissions of Corn Ethanol under the EPA RFS2
Twelve years of experience and improved analysis methods have provided new insight into the life cycle greenhouse gas (GHG) emissions from corn ethanol. This study reviews the key factors that affect the...
Analysis of EPA’s Proposed Rulemaking for 2020, 2021, and 2022 RVOs
This memorandum provides Net Gain’s comments and observations regarding selected technical issues associated with EPA’s Proposed Rule for the Renewable Fuel Standard (RFS) Program Rules for 2020, 2021, and 2022 Renewable Volume...
Assessment of a Reduction in the RVP of Conventional Gasoline in the Summer
The Renewable Fuels Association (RFA) retained MathPro Inc. to conduct a first-order analysis to estimate the additional costs that would be incurred by U.S. refiners if the RVP of conventional gasoline blendstock...
Analysis of Ethanol-Compatible Fleet for Calendar Year 2022
This study evaluates the size of the market that can consume E15 (a mixture of 15% ethanol and 85% gasoline (by volume) in calendar year 2022 in the U.S. The study computes...
Emissions Impacts of the Elimination of the 1-psi RVP Waiver for E10
The U.S. EPA Motor Vehicle Emission Simulator (MOVES) 3.0 model has been used to estimate the impact on air emissions from on-road gasoline/ethanol-powered vehicles if the 1-psi Reid vapor pressure (RVP) waiver...
Study on Economic Impact of Nationwide E15 Use
One of the most significant challenges and opportunities for the ethanol industry lies in expanding demand by increasing use of higher blend levels. Most of the motor gasoline used in the U.S....
