The D4 RIN is the tradable compliance certificate for the biomass-based diesel mandate in the Renewable Fuel Standard (RFS). Understanding the price dynamics of the D4 RIN is important for understanding the RFS because its price sets a ceiling on the ethanol RIN (D6) and because some observers...

Biofuels could provide up to 27% of total transport fuel worldwide by 2050. The use of transport fuels from biomass, when produced sustainably, can help cut petroleum use and reduce CO2 emissions in the transport sector, especially in heavy transport. Sustainable biofuel technologies, in...

In the absence of strong government policies, the IEA projects that the worldwide use of oil in transport will nearly double between 2000 and 2030, leading to a similar increase in greenhouse gas emissions. Bio fuels, such as ethanol, bio diesel, and other liquid and gaseous fuels, could offer...

Increased global demand for biofuels is placing increased pressure on agricultural systems at a time when traditional sources of yield improvements have been mostly exhausted, generating concerns about the future of food prices. This paper estimates the impact of global adoption of genetically...

Biofuel production is being promoted through various policies such as mandates and tax credits. This paper uses a dynamic, spatial, multi-market equilibrium model, Biofuel and Environmental Policy Analysis Model (BEPAM), to estimate the effects of these policies on cropland allocation, food and...

This paper estimates household preferences for ethanol as a gasoline substitute. I develop a theoretical model linking the shape of the ethanol demand curve to the distribution of price ratios at which individual households switch fuels. I estimate the model using data from many retail fueling...

We present a new framework to identify demand and supply elasticities of agricultural commodities using yield shocks - deviations from a time trend of output per area, which are predominantly caused by weather fluctuations. Demand is identified using current-period shocks that give rise to...

The history of innovation in the chemical industry offers many insights for accelerating energy innovation. In this chapter, we begin by laying out the early history of the chemical industry for an overview of the role innovation has played in its development. We then explore three noteworthy...
