Water requirement for biorefinery to meet the renewable fuel standard in the contiguous United States
Renewable biofuel production requires a considerable amount of water for biofuel conversion. However, it is still unclear how much water is needed in the Contiguous United States (CONUS) to convert feedstocks to biofuels and the associated impacts on local water availabilities. This study addresses …

Climate policy and the airline industry : emissions trading and renewable jet fuel
… EU Emissions Trading Scheme and a hypothetical renewable jet fuel mandate on US airlines. I find that both the EU Scheme up until 2020 and a renewable jet fuel mandate of 1 bn gallons per year from 2018 to 2022 would have a small impact on US airlines and emissions, and operations would continue …
